Extended Comments
White Pine is another cruiser with a workboat heritage. In general her hull is a "built down" Maine Lobsterboat. But I've made some changes, and the reason is weight
LCG in a traditional lobsterboat is just aft of amidships (station 5). This is achieved by pushing the engine forward of station 5 to balance fishing gear and fuel aft. So the hull is shaped with the LCB just aft of station 5. Great! she floats level and on her lines at rest with a given load. But the less than optimum LCB is a compromise to deal with great variations in loading and speed.
White Pine will never see such variations in load so we know her speed within a small range. From full to empty tanks is a difference of lbs, or about knots. Her S/L of 2.5 (FNV=1.7) at 15 knots dictates an ideal LCB of station 5.7. This works out perfectly with her arrangement. There is plenty of room under the deckhouse sole to center engine and tanks about the LCB. So as tanks go from full to empty LCG will remain the same. With this arrangement I can relax about weights, (all the major ones are in the middle of the boat), and be pretty sure White Pine will be a successful design.
