Val will likely negate any free surface effect by the increase to four tanks versus two. But the idea that a stiffer boat is inherently more desirable than a more tender boat is not necessarily vaild.
True, and generally, she's a bit "rolly" already, but my idea, in addition to getting the ton of water down low, is to convert an existing SS tank below the engine (formerly a holding tank, and now clean and empty) into a third diesel day tank, post filtering. This will give me 40% more fuel, plus considerable range on "non-suspect fuel" should water or really fouled fuel get into my main keel tanks (50 gal. x 2). I am thinking this will get all the weight where I want it and will solve some fuel management problems as well.
Fishing boats and ships have provisions for winging out tankage, thus raising the CG, for different loading conditions, particularly light ship conditions. Tankage so poisitioned increases the vessels moment of inertia and results in a better more comfortable ride. In fishing vessels it compensates for the catch stowed low in the hold.
My steel boat is vaguely trawler-like to begin with, but I don't anticipate adding radically to the weight even when fully provisioned. I will have 600 pounds of batteries, true, but they are practically AT the CG, and so shouldn't affect pitching much...wetted surface, maybe!
