Engineers such as Ivan and my mate would shake their heads in horror and the latter has done so before. Used to precise tolerances, they believe in designing the whole kaboodle from the start and once that’s done, it’s not altered nor interfered with.
I, on the other hand, always design choice into the plan. Some things, e.g. CLR, CB, overall buoyancy, sail spread, hull section shape – these are non-negotiable but even here I an “cheat” at will. A full length keel, longitudinally, buys a hell of a lot of room to move with placement of masts and sail, within tolerances of course.
With that elongated lateral resistance, then as long as the CE of the sail ends up slightly behind the CLR, the actual sail plan can be to my heart’s desire. Not only that but limitations can actually be designed to work for you.
For example, upwind, it is not at all efficient and results in drag if there’s more than one mast.…
