Re: Cockpit drain question
I think that before reengineering the cockpit drains, I would fill the cockpit with water and see how long it takes to drain. If that is more than 4 to 5 minutes, and you are going off shore then "more better" might be in order.
Westerlys are pretty robust boats built for the harsh conditions around England and one would hope that they have addressed this issue adequately.
During hurricane briefings here, the marina superintendent recommends that all transom aperatures be plugged with nerf balls as boats tied to piers will take waves washing upon their transoms and that sea water will be forced into any exhausts, vents etc., so adding a drain to the transom might be problematic.
