Appendix Table A: All boats tested with hull type and locations. August testing periods were in the upper 70 to 80 F range. September testing had lower air temperatures. Table B: There was a wide range of compartment surface temperatures before testing began. Temperatures were very high on sunny days with warm temperatures, sometimes reaching 120 F. Shaded parts of the compartments had lower temperatures and accounted for the large range of temperatures possible in a single compartment (Crestliner 1650 FishHawk 77 to 120 F). Table C: Livewell, anchor, and center compartment temperatures were measured and the times were quantified for the length of time that temperatures were above 110 F. These compartments were generally small in size and reached the target temperatures, especially the livewells. Only the Crownline 242 did not register any time above 110, but this compartment had a large anchor and rope present. However, the sensors did register temperatures of 109 with an input temperature of 112.9 (Figure D). A slightly higher input temperature (+1-2 ) may have resulted in hitting the target temperature. During testing of the Four Winns 248 Vista, water drained too quickly to submerge three of the sensors (NW on Figure C). Table D: Maximum temperature reached in livewell, anchor, and center compartments were mostly above 110 F. Inflow temperature ranged between 111.5 and 113.7 F. Average input temperature on the Tracker Targa V165 was lowest in the LW2 test at only 111.6. Table E: There was a large number of bilge and other types of open compartments tested. These ranged greatly in size and configuration, which played a role in the heating capacity. Most boats reached the 110 F target for some amount of time, but only a subset maintained the temperature for 5 minutes. Compartment temperature (Table F) may have been maintained for longer time periods if the tests had been extended to a longer time period. Table F: Temperatures were lower in some of the bilge compartments because of the presence of water in the compartment or because of the size of the compartment. Most sensors recored temperatures greater than 100 F. Figures A to C: Compartment location, number, and size varied by boat type, size, and use. Sensor locations are shown and were placed in the corners of the compartments. Boats are listed in the order they were tested. Figure D: These figures show the same information as Table D. Average inflow temperature was near the maximum recorded temperature for the sensors. The Four Winns 248 Vista did not have water touching three of the four sensors because of the draining of the compartment. Figure E: These figures show the same information as Table F. Smaller boats (A) had inflow temperatures rise to nearer to sensor temperatures than in larger boats (B). Figure F and G: Livewells, even when not reaching the temperature for 5 minutes, all showed trends of increasing temperature to 110 F. The sensors had a shared pattern of dropping as the hot water cooled when touching the compartment, then increasing as the hot water warmed the compartment. Inflow temperature showed some variation during the tests and the average temperature of the inflow was related to the ability to warm the compartments to the target temperature. 1
Figure: H and I: Anchor compartments had a large range of measured temperatures. Some compartments, like the Four Winns 248 Vista, had drains in the compartment, so water did not fill the compartment and three sensors were not submerged. Center compartments in the Boston Whalers were large but reached 110 F in the 22 ft boat. Figure J and K: Bilge sensor temperatures for boats less than 17 ft showed a trend of increase to near or above 110 F. The fluctuations in the inflow temperature from the Glastron was due to changes in water pressure, which caused fluctuations in temperature. The average inflow was in the target range. Figure L and M: Bilge sensor temperature in large boats did not reach the target temperature as often as the smaller boats. The sensors did show temperature increases in the compartments, but more time or higher temperature would help reach the target. Temperatures plateaued at a few degrees below the input temperature, so an increase of 1-2 F could increase the sensor temperature by a similar margin. The Carver had water in the bilge compartment, but was still able to raise the temperature of the compartment to near the target temperature. Some sensors, such as the Monarch Little Giant sensors B and C, were dewatered when the bilge pump ran. Figure N: We tested the difference in bilge compartment temperatures between hull type for boats on trailers (left) and in water (right). There were not significant differences between the bilge sensor temperature measurements when compared by hull type for each location separately (ANOVA). Figure O: We tested the difference in bilge temperature based on location of the boat. There was a significantly lower bilge temperature for boats that were in the water, compared to boats on trailers (ANOVA p=0.0048). Boats in water were also larger than boats on trailers, which would have also have larger compartments. Figure P and Q: Inflow and outflow temperatures were similar in livewells, anchor, and center compartments. When there was a lag in the increase of the outflow temperature, there was no outflow until the compartment had filled to a specific level in the compartment. Figure R: Timing of bilge pump cycles influenced the outflow temperature in the smaller boats. Figure S and T: Large boats had fluctuations in the outflow temperature due to the turning on and off of the bilge pump. The increasing temperature of the outflow is shown in the graphs when the pump is running. 2
