SeaBoater Yacht Hull Building Technologies The SeaBoater is a shipyard that builds semi-custom or custom yachts, and our superior fiberglass hulls are not the typical "serialized" fiberglass hulls built by other shipyards that have yacht models available on the market. The superiority of fiberglass over aluminum and steel hulls is demonstrated with our specialized SeaBoater hull building. SeaBoater uses a special composite fiberglass hull structure, building it with a combination composite of multi-axial and uni-directional fibers. Building it in this way with fiberglass for the yacht hulls makes it close to steel in strength, but it is much lighter than a comparable steel vessel. Additionally, SeaBoater uses one of the great advantages of GRP, which is that the thickness and strengthening can be concentrated exactly where it is required by locally increasing the thickness in specific areas, something that cannot be easily done with steel. Fiberglass hulls built in this way can absorb the highest impact by cushioning loadings on the hull structure, so the advantage of steel in strength is effectively neutralized. As we see it, using pure fiberglass material combined with our specialized way of hull building creates a superior product, making our fiberglass yacht hulls even stronger than other hulls of aluminum and steel. However, we are aware of all uses for additional carbon hull reinforcements. Pure carbon fiber yacht construction is technically not a problem for our shipyard, but this technology is still extremely costly. The SeaBoater has its own way of yacht building, following classic fiberglass and epoxy resin technology, but with additional carbon hull reinforcement solutions. One or both solutions below depend on the models and the specific requirements of the client. We are mostly using these additional carbon hull reinforcement solutions: 1. Carbon Fiber Taped Reinforced Hull Areas Carbon Fiber Tape is used to improve tensile, compressive strength and stiffness in one direction, while adding minimum thickness and weight. Reinforcing tape with fiber bundles held in place by an epoxy filled thread is used for easy handling and wet out. This is not a costly solution, but makes a great additional fiberglass reinforcement of the hull areas on all connection places and other required locations. The whole hull of the SeaBoater 78.7 Kiteboat is reinforced in this way with Carbon Fiber Tape. 2. Carbon Nanotube (CNT) technologies Carbon Nanotube (CNT) technologies improve the properties of fiberglass composite yachtbuilding materials. Carbon Nanotubes are eco-friendly, anti-fouling, thermal protected and mechanical reinforcements. And on top of it all, they are very cost effective, so that the boat will not have the high hull building costs as associated with pure carbon hull production. It is pretty
clear that the hull will not have the lightness of pure carbon boats, but we have taken cost effectiveness one step further by making a stronger fiberglass hull that can be compared with metal boats and is a lot lighter than metal boats. This is our favorite yacht hull building technology. Carbon nano-composite materials offer top-quality effectiveness even above conventional composites, and together with aluminum and steel, they make a superior product, and you can see the statistics below. CNT vs. Composites*: Higher impact resistance compared to conventional composites as shown below: +50% Flexural Modulus +42% Glc Strain Energy Release +28% Compression Strength +20% Tensile Strength +18% Tensile Modulus +18% Flexural Strength +17% Compression Modulus CNT vs. Aluminum*: +66% lighter than aluminum 8x stronger than aluminum Other*: +25% greater Shear Strength than Welding (Repairs are simple as fiberglass, but with the advantage of up to a 25% greater shear strength than welding.)
SeaBoater 787 Kiteboat Profile Features SAFETY AND STRUCTURAL FEATURES 1. Carbon Fiber Tape Reinforced Hull Areas Carbon Fiber Tape is used to improve tensile, compressive strength and stiffness in one direction, while adding minimum thickness and weight. Reinforcing tape with fiber bundles held in place by an epoxy fill thread for easy handling and wet out. This is not a costly solution, but makes a great additional fiberglass reinforcement of the hull areas on all connection places and other required places. The whole hull of the SeaBoater 787 Kiteboat is reinforced in this way with Carbon Fiber Tape. 2. Reinforced Impact Areas Reinforced Impact Areas are in three areas of the hull, where damage most usually comes from floating or underwater objects. These types of areas are heavily and additionally laminated, above and beyond regular laminates, using added layers of fiberglass and Carbon Fiber Tape for support, thereby reducing damage in case there is an impact. 3. Watertight Collision Bulkhead The Watertight Collision Bulkhead is a vertical bulkhead extended up from the bottom of the hull. The Collision Bulkhead is a heavily bonded bulkhead with a watertight department that helps to contain seawater within it, in case of damage to the bow. Additionally, the Seboater 787 Kiteboat has a collision bulkhead with two fully watertight bulkheads. 4. Double Bottom with Watertight Bulkheads Watertight Bulkheads and Integral Tanks share the yacht bottom, which is divided into a number of watertight compartments, to increase the watertight integrity of the yacht and to create "the double bottom" effect. This significantly helps to avoid the breakthrough of water due to damage in the ship s hull. In addition, it helps in increasing the transverse strength of the ship which helps in reducing raking. 5. Full Double Hull Solution A double hull is a yacht hull design and construction method where the bottom and sides of the yacht have two complete layers of watertight hull surface, and the SeaBoater 787 Kiteboat will use this safety construction solution. The space between the two hulls is used for high quality sound and temperature isolation. 6. Propeller Skegs The rudders additional safety are realized through propeller skegs isolated from the hull by extra laminates that protect rudders in case of any collisions with floating objects or other underwater items. Additionally, propeller skegs are designed for bearing grounding loads on shore.
7. Rudders Additional Safety Both rudders stuffing boxes are at the same time watertight in the Rudder Department. This helps prevent seawater from getting into the hull in case of damage to the rudder stuffing box. Moreover, these full carbon rudders are on shafts twice the size of Lloyd s rule requirements. Additionally, we are using dual hydraulic systems, each one completely independent from the other. 8. Fully protected "Kort nozzle" propellers The benefits of Kort Nozzles are well known for towing vessels like tugs and fishing boats. However, considerable improvements in the overall efficiency of the propeller at low speeds (below ten knots) are great solution for electric engines of low power like we use for the SeaBoater 787 Kiteboat. Bollard pull on a tug fitted with a Kort nozzle may be up to 30% higher in some situations than the bollard pull on a similar tug with a traditional open propeller. Additionally, the propeller shell protects the propeller from ropes in the sea and similar underwater potential dangers. Over-sized prop shafts additionally increase the safety of the whole propeller system. 9. Integral Additional Strength Tank System The tanks, as opposed to simply being dropped into position, are heavily laminated inside the hull. The baffles, lids, stringers, and carbon reinforcement lamination all together interact to form a rock solid structure to distribute sea loads over the large area. It has two main benefits: First, it is possible to have tremendous quantities of liquid carried low into the hull, exactly where it is needed to increase stability. Second, the integral tanks produce an additional safety element in collisions because of the double-bottom hull effect. 10. Dual Fresh Water System The Dual Fresh Water System is two entirely independent fresh water source systems. Each system has its own water tank, filter, vent, and pickup. If any toxic contamination takes place, or any transport problem happens in one system, then a turn of the valves puts the second system on line promptly. 11. Plumbing Many vessels are featured with plenty of hull holes. Every pump, sink or salt water user seems to have its own hole in the bottom of the boat hull. Every one of these holes can produce a leaking and in a worst case scenario sink the boat. We are reducing below the waterline most of these holes in the hull, and those that really must be in place are protected with a water tight bulkhead (engine room and forepeak). These holes are in the form of added standpipes, to reduce the chance of an accidental failing. Regarding the head exhausts and the forepeak salt water source, the standpipes end over the waterline. The other exhausts bilge pumps, sump pumps and sinks are over the waterline.
SEAWORTHY FEATURES 1. Kite sail generator room The SeaBoater 787 Kiteboat uses kites and wind energy as its main propulsion power. Large kites can have the towing power equivalent to a 6,800 HP engine! When the boat cannot or does not wish to use kite towing power from the bigger kite, then it can apply to a smaller kite solution for producing electricity for the electric engine only. Here in the bow, below the deck, is the generator room with a generator connected to the kite. 2. Seaworthy Stability Characteristics Great stability characteristics are created by the revolutionary hull design; the width of the hull like the catamaran is combined with controlled monohull stability, which results in creating a comfortable motion on the sea and a high ultimate stability for safety. Extreme weather survival capability and high ultimate stability of yacht is the final result of the SeaBoater 787 Kiteboat hull design. 3. Skegs ahead rudders The skeg protects the prop and rudder from most underwater objects, but it really helps to balance the bow too. The big rudder and skeg operate to reduce prop "walk" in reverse too. Commonly, when it is most necessary in heavy seas or for docking maneuvers, effective turning movements can be produced by a well-planned and built rudder/skeg combination. 4. Active Stabilizers We are using 12-square-foot foils; these are almost three times bigger than standard conventional usage requirements. The leading qualification to use over-sized stabilizer actuators was to handle damaging weather in a turbulent and dangerous breaking sea. Calculations show that a two to three percent drag punishment happens, because of these oversized fins. However, when they start to operate, the drag punishment disappears and, in a way, they may be more effective compared to smaller fins in larger waves. Additionally, there are stabilizer actuators in watertight coffer dams. 5. Bow boat control panel The bow boat control panel is a smart feature to help manage the boat in ports, unfamiliar waters, through the night or in any hard-to-maneuver conditions. 6. Yacht boarding platform The SeaBoater 787 Kiteboat has one of the best yacht boarding platforms ever seen in yacht construction. At the same time, there exists side by side the best combination for safety and pleasure features. You can see here the main points of these features:
- A safe and easy way for recovery of a man overboard situation. It is also designed to be self-rescuing in that scenario. - Enormous protection against seas and winter from the left and right sides. - A flat and big stable platform from which to step directly into a dinghy safely and a ladder lay-up of the dinghy into a storage place with "hand-hold" distance. - Comfort features include a beach on the ship for swimming, showering, or scuba diving, which are both safe and pleasant. PLEASURE AND COMFORT FEATURES Extreme weather survival capability of the yacht, with pleasure and comfort at the same time, is one of the main targets of the SeaBoater 787 Kiteboat construction. 1. More living space The SeaBoater 787 Kiteboat has more living space than monohulls and catamarans of the same type. To eat, sleep, and live far more comfortably than a catamaran looks impossible, but it is a true fact here, because the SeaBoater 787 Kiteboat does not have a hole in between the hulls, but the boat still has the width of a catamaran. 2. Dinghy storage and engine room The launching and retrieval of dinghies are an easy and reliable task on the yacht with a boarding platform like the SeaBoater 787 Kiteboat. There are two dinghy storage and engine rooms, which are more efficient and best for safety features on top of it all. 3. Higher hull edges The hull edges are 120 cm high. These higher hull edges make the boat a lot safer and practically eliminate man-over-board issues. Additionally, the yacht is more protected in high waves and rough weather conditions. 4. Large battery bank The battery bank is the heart of the DC system. The size of the battery bank is the choice of the client. There exists space for a large battery bank, which can increase comfortable living conditions on the yacht. 5. Alternate energy needs (solar panels) Alternate energy needs are available with a significant number of solar panels for use on the wide roof as a possibility. This is an optional solution.
