Taipan 28 - How well offshore?
So the numbers for the Taipan 28 are more like 3600 lbs. ballast and 7900 displacement? Wow.
My gut reaction is Jeff''s concern about low density ballast is well taken. If you''re carrying almost half your displacement as ballast relatively close to the bottom of the hull, it will get you a certain amount of stability, but a much better and stiffer design would put a bulb of lead (weighing, say, a ton, or about 40 percent less than your cast iron ballast) at the end of a 6 foot keel, giving you the same or lower center of gravity, and giving your hull much more freeboard and reserve buoyancy due to the reduced displacement. The Cadet design would be great for getting into the shallows here on the Chesapeake bay while still having decent stability and righting moment, but it seems the lower, lighter ballast might be better suited for serious ocean sailing.
