IIRC, the regs about the washboards are based on the assumption that the
cockpit does *not* clear. I think there were some [monohull] incidents
where cockpit drains were blocked by ropes or loose items of clothing or
somesuch. So I think you'd have to establish a completely different
principle before your calculations could be considered, which sounds
like an uphill task. JMHO.

Perhaps another approach is to buy a light airs sail. Then you can
rename your current one as the heavy weather jib! And the lightweight
sail could be useful, if you have some way to fly it.
