New stability curve is available for SINGLE keel BS36 in file section.
AVS=180 deg, Max. Dynamic Heeling Angle ~120 deg.
Based on 3D model. It still not perfect, but more accurate than last one (includes clarifications from Brent for foot well, cabin, pilothouse) and LEAD ballast.
Please note: this model has STEEL mast and boom.
REPLY FROM BRENT:
Up until 1984 , we used to cut a 5 1/2 inch sheer in the bulwark plate on the 36. Then I found out that the factory edge makes a good looking sheer , sio started using the factory edge. Some boats are still done with the cut sheer , as some prefer the more traditional sheer , even if it means giving up that much more interior space.
The stabilty curves posted are for the boat with the cut sheer, with about 5 1/2 inches less freeboard amidships. A stability curve with the new factory edge sheer will show a much higher ultimate stability angle. Raising the buoyancy of the cabin , wheelhouse( about ten thosand pounds of buoyancy) as well as the decks, will make a huge increase in ultimate stability.
