I've got this report from Tayana for the Vancouver 460 Pilot
but don't know how good it is.

I have another idea.

Since this boat has a 325-gallon fuel tank and a 240-gallon
water tank and the inclining experiment was done with all
tanks half full, would I be able to significantly improve on
the stability if I fill up all the tanks for my offshore cruising ?

I can install a watermaker and solar panels so I won't have to
draw too much water and fuel from these tanks.
