OPERATIONS MANUAL for LUNASEA Bayliner 4588 Familiarize yourself with the various systems outlined in this manual. This boat has many features that are designed for comfort, convenience and safety. Proper use and thoughtful care will ensure your trip will be safe and relaxing. Important points: 1. Monitor your use of electricity carefully. LUNASEA has a great number of electrical circuits and devices both AC & DC. Care should be taken not to exceed the boat's limit to provide electrical power. 2. The propane tank for the Bar B Q should be stored on the top deck in it s container and not in the lazarette or on back deck. Propane gas is heavier than air and will accumulate in the lowest point of the boat if the valve is not closed tightly or if the tank develops a leak. If in doubt ventilate the engine room using the blower system ASAP and before starting the engines. I. Pre-Start Check List Before you operate the vessel for the day, do an inspection of the mechanical systems and the engine room. Any problem is much easier to fix while securely tied up at a dock, or even at anchor, than it is adrift mid-channel somewhere. A. MAIN ENGINES 1. Turn on engine room light - breaker on 12 volt panel Pilot House. 2. Grab a flashlight and enter engine room via hatch that is under the stairs that proceed down from galley. 3. Check oil level in main engines. Dipsticks are down low near center of engines facing centerline of boat. Do not use the upper dipsticks which are for a road vehicle usage. 4. Check fresh water coolant level. This must be done by opening hatches in main salon. 5. Check for water in bilge, general condition of belts, hoses and fuel lines. 6. Check sea strainers in aft part of engine room for obvious obstructions. NOTE: When sea strainers are obstructed or in case of engine overheating or lack of raw water coming from exhaust, shut down engine immediately. Then close through hull for engine raw water intake, and disassemble sea strainer and clean basket. Re-assemble sea strainer, open through hull and restart engine. Check immediately for water flow out of exhaust. Make sure raw water system has picked up a prime. If not, close through hull and open top of sea strainer and fill to brim with water. Reassemble sea strainer, open through hull, restart engine and check for raw water flow. 7. Check transmission fluid levels. Take care in reinserting dipsticks. 8. Exit engine room and secure hatch. 9. Turn off engine room lights. B. GENERATOR This should be checked each time prior to running. 1. Open up center lazarette. 2. Open sound shield. 3. Check oil - dipstick is down low on engine, starboard side. 4. Check fresh water coolant in cockpit locker, port side. 5. Check sea strainer for obvious obstructions. (See A. Main Engines above) 6. Re-attach sound shield and close lazarette. C. BATTERIES Check water level in starting battery located in port lazerette, house battery located in starboard lazerette, generator battery located in starboard lazerette and the dinghy battery located under the helm seat at least once per week. The electrolyte fluid should be well above the battery plates and preferably up to ring. Fill with distilled water located in starboard lazerette. The inverter batteries are located aft of the holding tank and outside of the starboard engine.
II. Starting Main Engines After your engine room check, you are ready to start main engines. 1. Turn on the Mathers electronic control ciruit breakers in the Salon Starboard aft cabinet. There will be a Chirping warning tone until one of the four sets of controls is selected as the active set. Choose the control set at the Pilot house or Flybridge where ignition keys will be used. 2. Turn on main engine ignition breakers at top of 12-volt panel in Pilot House. 3. Preheat engine on initial start. To use preheater, turn key to on and depress preheat button. When light goes out, turn key to right to start. 4. Make sure gear shift at the selected station is in neutral. Engines will not start unless gear shift is in neutral and Mathers control unit has power and is slected (red light on). 5. Turn key to right. Engine should start and alarms should stop after several seconds. Observe readings on tachometer, voltmeter gauge, and oil pressure. Engine temperature should rise slowly. 6. Start each engine independently and monitor each set of gauges. Start the starboard engine first. 7. Observe the exhaust from each engine and make sure that raw water is coming from exhaust. If not, shut down engine and determine reason why not. If raw water strainer is obstructed, clean as described above under A. Main Engines. Is through hull valve open? Is raw water pump working? 8. When underway do not increase RPMs above 1000 rpm until engine temp has risen to 150 degrees. III. Engine Shutdown 1. IMPORTANT: DO NOT TURN OFF KEY TO SHUT DOWN ENGINES. This will result in damage to alternators. 2. Allow engines to idle for at least 5 minutes after running at planing speeds and high RPMs. This allows turbocharger to cool down and prevents damage. Typically this time fits well with mooring or anchoring. 3. Depress engine shut-off switch (button) until engine completely dies and alarms sound. 4. Turn off key. Repeat for other engine. When done, switch off ignition circuit breaker on 12 volt panel. 5. The engine can also be stopped by manually pushing in the fuel shut off solenoid located on the upper port side of each engine just aft of the mid point of the engine. IV. Electrical System This yacht has a vast array of electrical circuits and devices. The electrical system is generally divided into two subsystems: 110 volt AC and 12 volt DC. This vessel's potential to consume electricity exceeds its capacity to provide it or to make it. When any electrical device or circuit is not needed, be sure the device and the circuit is turned off. 110 VOLT SYSTEM 110 Volt electricity is used to run TV/VCR, Stereo, electric heat, microwave, wall outlets, battery chargers etc. 1. The 110 Volt system breakers are on the left-hand side, or forward half of the electrical panel console on the starboard side of the pilothouse. 2. 110 Volt power can be obtained from three sources: a) shore power b) generator c) inverter A. SHORE POWER Three shore power inlets are on the starboard side above the rail on the side of the pilot house. Each inlet is for a 30 amp cord. Typically, one 30 amp cord will be used. If there is a second and third 30 amp outlet available, the second and third power cords can be used. Normally only one outlet will be available so for convenience you can use one or both of the 30 amp Y pigtails. This allows you to energize any 110 volt circuit for convenience but
the sum of the current draws (each line has its own ammeter) can not exceed 30 amps or the circuit breaker on the dock will trip off. The forward most inlet corresponds to line #1 at the top of the 110V panel in the console. Line #2 corresponds to the center inlet, line #3 to the aft most inlet. If one 30 amp source is used, all three rows of 110 circuits can be used by using one or both of the Y connectors to connect line #1 with line #2 and/or with line #3 etc. You may also use 2 of the 50 foot 30 amp cords and one Y and connect them to either 2 dockside 30 amp outlets or to one 50 amp outlet which may sometimes be available using the reverse Y 50 amp to 2-30 amp connectors pigtail. 1. Before plugging into shore power make sure all 110 volt circuit breakers are turned off. 2. Turn upper inverter/off/shore-gen switch to shore/gen and the lower shore/off /ship switch to off or to Shore. 3. Plug in as described. 4. If Polarity light flashes, unplug and notify dockmaster. 5. Switch on loads as needed but be sure not to exceed ampere loads. NOTE: You cannot use all 110 circuits and electrical items with only one 30 amp inlet source. It will pop the circuit breaker. If you use electric heat, you cannot add the electric water heater, microwave, etc. Priority should always be given to the battery charger breaker that charges the engine, house and generator batteries and the inverter charger breaker which charges the inverter batteries. B. GENERATOR When shore power is unavailable, ample 110 volt power can be provided by the generator. 1. To start generator, turn off all 110 volt breakers and be sure upper inverter/off/shore-gen switch is turned to shore/gen. Turn lower Dockside/off/generator selector switch to off. 2. Depress pre-heat switch next to generator start switch for 10-15 seconds. 3. While still holding pre-heat switch on, turn generator start switch to start and hold until generator starts running. NOTE: The boat needs to be relatively quiet to hear this. 4. When generator begins to run, release the start switch which will turn to run but continue holding the preheat switch on for 5 seconds (the pre heat switch also holds in the fuel solenoid until the alternator produces enough power to energize the solenoid and overrides the low oil pressure shut off). 5. Leave generator switch on run and switch lower selector switch to "generator". 6. Check oil pressure gauge, voltmeter and rising temperature gauge. Observe exhaust at port side of the transom under the swimstep, to be sure raw coolant water is coming through. If not, shut down generator and follow steps outlined for lack of outflow for main engines outlined above in A. Main Engines. 7. The line breaker for the generator is on the left hand end (forward) of the electrical panel console. 8. Allow generator temperature to warm up to at least 140 degrees before switching on any loads. 9. Turn the lower selector switch to generator and slowly begin to switch on desired 110 volt circuits. 10. Never run generator for less than 30 minutes. It is best to run it for an hour at a time or more. 11. Do not let the generator run without load, preferably at least half load. Leave chargers, water heater, refrigerator, ice maker, even cabin heat operating to maintain load. An unloaded generator can cause engine and injector problems. 12. To turn off generator, reverse start-up process by switching off all 110 volt circuits first. After removing all loads, allow generator to cool down by running unloaded for 3 to 5 minutes. After cool down, turn generator start switch to off and wait until you hear the generator shut down. C. INVERTER
110 volt power can be provided by the inverter which uses 12 volt battery power to make 110 volt AC current. 110 volt power is very limited with the inverter because it comes from a limited source. The inverter supplies 110 volt power to the center bank (line 2) of circuit breakers on the 110 volt panel only, except that no power is provided to the electric range. This covers all the 110 volt plugs, ights,refrigerator etc. You cannot run space heaters, microwave, hair dryers, TV/VCR at the same time or for any length of time. Do not run high resistance loads such as space heaters, water heater or stove with inverter power. It will drain the batteries very quickly. The inverter's best use is to provide light, intermittent 110 volt power during an evening to save the generator from constant short start-ups and shut downs. When the boat is on shore power or has the generator running, turn on the 110 volt inverter charger switch, as the inverter becomes a battery charger for the inverter batteries. The inverter batteries are 4-6 volt (2 in parallel and they both are in series with the other 2) gel deep cycle golf cart batteries which are charged directly by the port engine alternator. The inverter is located under the center starboard salon settee cushion. The top left (forward) button is the on/off switch. If the inverter detects a fault, it will trip off. Press the on/off switch twice to turn off and back on again to re-start inverter. 1. The remote switch and indicator panel for the inverter is located on the right hand (aft) inside wall of the electrical panel console. 2. Before switching the upper selector switch to inverter, turn off all 110 volt circuit breakers. 3. Turn the upper switch marked inverter/off/shore-gen to inverter. 4. The inverter only provides 110 volt power when a load is applied, so you can test its operation by turning on the 110 volt table light in the salon. When there is no shore power source and the generator is not running, turn inverter off when 110 volt power is not needed. This should be done at night while at anchor, etc. When using the inverter alone for 110 volt power, make sure the battery charger breakers are off on the 110 volt panel. 5. Before starting generator or plugging into shore power make sure upper inverter switch is turned to off or shore/gen. E. ELECTRIC WATER HEATER Electric water heater runs off of 110 volt system. It should be used only on shore power or with the generator in operation.. The circuit breaker is on the 110 volt panel. EXTREMELY IMPORTANT: Do not use the electric water heater if the water tanks are very low or if they run dry. The electric element will burn up if the tank has no water. F. 12 VOLT SYSTEM The 12 volt system runs the electrical systems necessary to operate the vessel. Bilge pumps, water pump, electric toilets, navigation lights, house lights, electronics, etc. are 12 volt systems. The 12 volt circuit breakers are located on the right-hand (aft most) half of the electrical panel console in pilothouse. Use only the circuits needed while keeping the others off. There are sufficient lights and other 12 volt devices to drain the house batteries of power if they were all left on during a long evening. Be careful to not leave the normally off switches turned on, such as the engine room lights, search light, wash down pump, etc. Also leave the normally on switches turned on such as the head blower (vent) and the shower sump pump (also drains aft head sink). The starboard engine alternator charges the house or accessory battery which is located in the starboard lazerette. There is an isolator eliminator which allows this alternator/battery system and the 110 volt charger to maintain the starter battery s charge. G. BATTERY SWITCHES The battery switch box is located in the main salon in the cabinet just to starboard of the entry door. You may leave these switches on unless the boat is going to be left unattended and without shore power. Each switch is marked as to which battery bank it corresponds to. The crossover switch is used to jump the engine starting batteries with the house battery. Leave this switch off unless the starting batteries have insufficient power to crank the engines. Do not switch the crossover switch in either direction when the engines are running as you can blow a diode and damage charging system. Wait until you turn off engines the next time and turn switch them. The three automatic bilge pumps are powered even if the main switches are turned off.
EXTREMELY IMPORTANT: Make sure inverter switch and battery charger breaker are off before crossover switch is turned on. If both are on when crossover switch is turned on, it will destroy the inverter. V. Marine Heads and Holding Tank This vessel has two heads, each with an electric vacuflush toilet. It has one holding tank. A. VACUFLUSH TOILETS It is critical that every member of the crew be informed regarding the proper use of marine Vacuflush toilets. NEVER dispose of paper towels, tampons, Kleenex, sanitary napkins, household toilet tissue, undigested food, etc., in the marine toilets. In the event of seasickness, DO NOT USE THE MARINE TOILETS. The valves, bellows, openings and pumps are extremely small and will clog very easily. A clogged toilet can be very expensive to repair, leave a huge mess and potentially ruin a vacation. Keep toilet lid closed when not in use to avoid inadvertently dropping or knocking something into toilet. 1. To operate electric toilets, make sure breaker is on at 12 volt panel in pilothouse. 2. As the Vacuflush system uses fresh water to flush, the fresh (potable) water pump breaker switch must be turned on at the panel, there must be fresh water in the tank(s) and one water tank selector valve must be open. 3. Also each Head is fused next to the head with 10 amp fuse. A rhythmic pump sound will be heard which should last for about one minute this is the diaphragm (bellows) pump building a vacuum in the accumulator tank. If the toilet is already at a vacuum there will be no sound. 4. If the bowl is dry, you can add a slight amount of water to the bowl by gently raising the flush foot pedal (on left side of toilet). 5. When finished, quickly and gently depress foot pedal and hold open for 2 to 3 seconds and then release. The vacuum will evacuate the bowl (with the woosh sound like an airplane toilet) and fresh water will slightly fill bowl. 6. The diaphragm pump will continue pumping for about one minute. 7. The Vacuflush system only uses about a pint of fresh water per flush and extends the effective capacity of the holding tank compared to a conventional macerator pump marine toilet. Without sea water in the waste system also reduces or eliminates odors, which come primarily from the marine matter drawn in by the head pump. B. Y - VALVES This vessel has no Y Valves and all head discharge goes to the holding tank. BE SURE you are familiar with applicable laws concerning use of holding tanks and dumping of sewage overboard. Generally you must use the pump-out stations at marinas in the U.S. but can pump overboard in Canada outside of restricted areas. It is common courtesy to not use the overboard discharge in marinas. You will also cause an odor which you are most likely to smell more than others. The best practical solution in Canada is to use the macerator discharge pump when you are under way in deep water away from other boats, homes or fishing areas/shellfish beds. C. HOLDING TANK The holding tank is located under aft head vanity, starboard side. IMPORTANT: You must be mindful of the extent of your crew's use of the holding tank. Do not rely only on the holding tank warning light located forward of the Starboard Pilot house door - the light comes on when the tank is nearly totally full. You can monitor the tank level in the aft head Tank Level Indicator with quarter tank calibration points. NEVER overfill the holding tank. It is possible to break a hose, clog a vent, or burst the tank if it is used when it is full. The result is an indescribable catastrophe and a costly repair bill. The Tank Level Meter is on the aft head electrical circuit which must be on to operate. Pumping out the holding tank is done one of two ways. 1. There is a deck pump out fitting on the starboard side deck, for use with marina pump out stations. Ask the marina staff for instructions about their procedures. 2. The contents of the holding tank can be pumped overboard with the macerator discharge pump in appropriate areas. In Canada where this is the only option, it is smart to periodically pump out the holding tank when cruising slowly in deep water away from shore or aquaculture farms.
1. Depress the macerator switch near bottom of 12-volt panel to run discharge pump, switch is spring loaded and must be held in to operate the macerator pumo. 3. Listen carefully to the sound of the pump's operation, when pitch of motor changes or goes high discontinue operation. You may also observe the effluent discharging from the overboard discharge port on the starboard side just aft of the pilothouse. When the effluent stops, turn off the pump. 4. NEVER run pump for lengthy periods or when holding tank is empty to prevent pump burnout. 5. When finished pumping, clean any waste that may have splashed on the starboard side of boat around pump outlet using washdown hose or old deck brush and plenty of seawater. A full tank can be pumped out is approximately 3 minutes. VI. Anchor Windlass and Davit System The anchor windlass and davit motors use a large amount of electrical power. It is always best to have the starboard engine running (at about 800 to 900 RPM) when operating the windlass or the dinghy davit. Also check voltmeter to be sure alternator is charging batteries. If not, start the generator if not on shore power and use battery charger. The switch for the windlass is located on inside, left-hand (forward) wall of electrical panel console in the pilothouse. The breaker for the windlass and the davit is on the bottom left (starboard) side of the main switch panel in the salon, port of the cockpit door. A. WINDLASS AND ANCHOR 1. Turn on windlass switch in pilothouse. 2. Always use proper anchoring procedures when anchoring. 3. Bring boat to complete stop before lowering anchor. 4. Pay out sufficient scope before setting anchor. The chain has a white mark every 10 feet and a red mark every 50 feet. 5. Monitor vessel's position periodically after setting anchor to see that anchor remains set. This is important if it becomes windy or there is a current. 6. Always start starboard or both main engines before you begin to weigh anchor. 7. Do not use windlass to pull boat toward anchor, use the engines to advance boat and use windlass only when chain is near vertical. 8. While bringing in chain, operate windlass slowly and watch that chain doesn t bind against hawspipe where chain goes into chain locker. Keep fingers and toes away from windlass and chain when operating or whenever switch is turned on. Have all others (especially children) keep clear of windlass and switches to avoid inadvertantly stepping on switches or risk of injury from windlass. 9. Care should be taken that anchor does not swing into bow and that anchor arm is guided over pulpit rollers. 10. Wash off any mud or debris. Use the yellow chain brush, the old deck brush or the washdown pump. 11. When finished with windlass, turn off breaker at panel. B. DAVIT SYSTEM 1. Locate davit remote control and cable in cabinet below electrical panel in pilothouse and plug into outlet next to davit on flybridge. Make it it fits snugly. 2. Make sure dinghy bridle is securely fastened to dinghy. Do not add any gear to dinghy, wait until it is in the water. It could add too much weight or unbalance the load. 3. Operate davit motor with remote but do not provide too much slack in cable, or it will come off pulley in davit arm. If it does come off, DO NOT OPERATE, place cable back on pulley (se below). Attach hook to bridle. Put lower drain plug in thru hull. 4. IMPORTANT: It is best to use two people to lower dinghy -one person on flybridge and one ready to move along portside decks to guide dinghy safely past salon windows into the water. 5. Be sure to handle the bow and stern lines simultaneously on the dinghy to keep it straight. Life jackets for the operators are a good idea.
6. If cable slackens too much (i.e.: after lowering dinghy), it can come off pulley at top of boom. Do not operate with cable off pulley. The operation will be more difficult under load. The cable will fray, weaken and break. To re-position cable on pulley, simply unload and slacken cable and then slip cable over pulley. 7. To lower dinghy, first raise it slightly to clear mounting blocks. Push davit arm and dinghy out over side of boat and as you do, rotate dinghy so that bow points aft. Lower dinghy carefully to avoid contact with the boat - especially the salon windows. 8. Raise the dinghy in the reverse order. The bow of dinghy should be just aft of the flybridge seat. Fasten the 2 straps and bow shackle before moving boat. C. DINGHY USE 40 HP Mercury & AB 12 ft RIB w/console 1. When starting, open vent in fuel tank and pump fuel line bulb until firm. 2. Make sure shift lever is in neutral when starting. You do not need to raise the fast idle lever. 3. Press key in toward console to choke engine. 4. IMPORTANT: This is a 4 stroke engine. DO NOT MIX GASOLINE WITH 2 CYCLE OIL. Like any 4 stroke engine check the oil level with the dipstick located at the aft stbd side just above where the housing joins the lower section. 5. Verify cooling water is coming out of stbd aft side while operating. 6. If battery is run down, you can trickle charge it in place using the long white and black leads attaching them to the house battery bank. Or you can remove and charge on shore. There also is a small trickle charger in the salon settee. VII. Propane Bar B Q 1. The propane tank is located behind flybridge settee. 2. The Bar B Q is located in the port lazerette. Place it in the 2 mounting holes in the port side of the aft rail. 3. Connect hose to tank. Turn on tank valve and light Bar B Q. NOTE: Propane gas is heavier than air. Make sure tank valve is shut off after use of propane. It is very important to check bilges and lazarettes and run blower as needed after propane use and prior to starting engines. It is wise to never leave the tank in the cockpit in case a leak develops. Place and secure the tank on swimstep when anchored or docked. Place tank in container on flybridge when underway. VIII. Use of Autopilot (and knotmeter, depth sounder and wind speed) WARNING: IF AUTOPILOT IS ENGAGED, HELMSMAN SHOULD NEVER LEAVE HELM STATION WHEN THE BOAT IS UNDERWAY, VIGILANCE MUST BE MAINTAINED REGARDING THE CONDITION OF THE SEA AHEAD. Collision with floating debris can cause damage to the boat's hull, props, shafts and rudders as well as endanger the crew. 1. The Autopilot as well as the interconnected depth sounder, knot meter/log and wind speed indicator are turned on with a single circuit breaker labeled Autopilot in the main 12 volt panel in pilot house. 2. The Autopilot will be in Standby mode. The rudder indicator and the other electronics which are connected will all be operative. 3. The simplest operation is to bring boat onto your desired heading and then press the right red button marked Auto. This will maintain your heading in nearly any conditions except you may want to steer manually in heavy seas. 4. To take boat off Autopilot press the left red button marked Standby. 5. In view of the above warning, always keep your eyes looking ahead but the autopilot does allow you to concentrate on the sea conditions and allows you to pay less time watching your heading. 6. It is wise to practice using the Autopilot in calm sea conditions prior to using it extensively. 7. Practice turning the wheel to avoid objects so that you have the feeling of the boat s response. You can manually override the system to avoid objects by continuously turning the wheel and this is often the fastest way to turn the boat in an emergency. 8. To make a turn over 20 degrees, it is best to disengage the auto pilot and steer to the desired course manually. Otherwise, push the 10 degree turn button twice only, wait until the turn is nearly complete and push 10 degrees twice more etc.
IX. Use of GPS and Chart Plotter The GPS/CHART PLOTTER is considered a navigational aid. Feel free to use it but do not rely on it. The compass, charts, dividers, etc., are considered navigational tools. You must be continuously aware of your approximate position, course and speed using the navigational tools. Electrical problems can render electronic navigational aids unreliable or inoperable. See the manuals for all the capabilities of the various systems. C-Map chart cartridges for probably anywhere you would want to go are in the Pilothouse drawer and over the settee. Never set any portable electronic items such as radios near the magnetic compass. X. Engine Synchronizer Operation underway is simpler when using the engine synchronizer. Like the autopilot, the engine synchronizer allows the operator to concentrate on the water ahead and not on balancing the engines. The Auto-sync unit is easy to operate. It is always powered when engines are operating. Turn Auto sync switch off (at either helm station), light goes out. Bring boat up to operating speed with port engine (slave or follower) up to 100 RPM higher than starboard engine (leader or master). DO NOT push slave throttle all the way forward (as common with a different brand of synchronizer), always move the throttle together. Turn switch on and light will come on. Port engine will slowly come within 10 RPM of Starboard engine. You can adjust throttles up and down through a full range of cruising. Move throttles together when adjusting more than 100 RPM. If only one throttle is adjusted more than about 100 RPM, the synchronization will end and the engines will adjust to the RPM at which each throttle is positioned. XI. Diesel Space Heat This system provides heat any time you feel like it without running the generator or taxing limited shorepower. With the usually cool sea water temperature, it is often pleasant to even just take the chill off in the evening or morning. You may leave it off when you have adequate shorepower or running the generator and need little or no space heat. Important: The diesel heater is connected directly to the house battery. NEVER disconnect the power to the heater when diesel heater is operating. Turning off the heater in mid-cycle can result in damage to the diesel heater or start a fire. 1. The thermostat in the salon controls all air outlets. There is also an on/off lever under the thermostat itself, move lever to the left to turn on. 2. Some registers have an air damper to control heat in the area. 3. Suggested settings are to have the thermostat set at 70 degrees and adjust the dampers to make their areas comfortable. XI. VHF Radio There are 2 VHF radios. The main radio is a Standard full function radio in the pilothouse console. It has all the features including dual watch etc. It also is connected to the boat s GPS and is able to continuously broadcast the boat s lat/lon when the DISTRESS button is activated. The distress button is located under a clear flap on the face of the radio. Obviously, do not activate the distress feature except in an emergency. There is a Standard VHF radio in the enclosed locker on the flybridge port side. Channel 16 as it is constantly monitored by the US Coast Guard, Canadian Coast Guard and often by commercial rescue towboat operators. Citizens Band radios are also located in the pilothouse and on the bridge for non essential communications. XI. General Vessel Operation Always operate the vessel from the helm station that provides sufficient visibility given your course, speed and sea conditions. During docking maneuvers (that may require backing), always operate from flybridge as there is no visibility astern from the pilot house. There are two Mathers controls in the cockpit for close quarter docking, backing up, and fishing. It is best to center the rudder and use only the shifters/engines to maneuver the boat backwards or at very slow speeds. It is extremely important that the trim tabs be in the full up position (bow-up) whenever the boat is maneuvered for docking. Make certain throttles are all the way down and engines are at idle whenever you shift in or out of gears. Failure to do so can result in engine or transmission damage.
When planning a day's passage, it is good to have an alternative plan in the event of inclement weather, crew preference, etc. It is a good idea to refuel before the tanks reach 1/4 full. One reason is so that you are not searching for fuel with dangerously low tanks. Another reason is to prevent any sediments that may be in fuel tanks from entering fuel lines and prematurely clogging the fuel filters. Tank Capacity and other useful Facts 1. The fuel tanks are 500 gallons total, 250 on each side. The usable capacity according to Bayliner is 444 gallons total after allowance for pickup height and tank angle. The fuel consumption is about 0.8 nm per gallon at cruising speed of 15 to 18 knots but appreciably more at hull speed ie 8 knots. Allowing for refueling with a 25% reserve, this allows a comfortable range of about 250 nm. I have done 290 nm (and was sweating about refueling) at which point both gauges read 0.10 tank. I added 376 gallons which is about 0.85 of tank capacity and very little reserve. A useful check on fuel consumption is to record, from the Tridata unit in the pilothouse, the miles travelled between refuelings. You can plan your trip and fuel stops from the distance traveled and the fuel gauge. The Tridata trip display goes to zero when the autopilot switch on the 12 volt panel is switched off. 2. There are 2 water tanks located under the master stateroom bunk and filled from the 2 fillers on the port bow. The gauge on the main control panel operates when the tank monitor 12 volt switch is on and the toggle switch is toggled to #1 for the forward tank and to #2 for the aft tank. There are 2 selector valves located to port of the hot water tank to select either or both tanks. It is wise to draw down one tank at a time so you don t run out of water all at once. I prefer to draw down the aft tank first. If you use the Washer/Dryer expect to consume about 50 gallons for each load for the wash and rinse cycles. Unless both tanks are full, it is best to open both tank valves for the washer/dryer or you may run out of water using only one tank. 3. The holding tank is covered above and holds about 60 gallons. Don t ever let it fill to capacity.. Leave Tank Monitor 12 V switch on and keep an eye open for a lighted Red indicator light on Tank Monitor display. For more exact tank level, check the tank level gauge in the aft head by pushing the button. Enjoy your cruising on the LUNASEA. 4/22/2005
