Re: Cockpit Drains
1) Good question. Normally it's a good idea to have seacocks on any thru-hull penetration - but in the case of cockpit drains that are always left open, what are they for? You might argue that the boat hasn't sunk for 32 years now, so the design isn't all that bad. I guess the answer is that you should have seacocks, but they wouldn't be top of my list of things to do....
2) As pointed out in Coles & Bruce "Heavy Weather Sailing", the real equation here is how much weight of water is in a fully flooded cockpit, how that relates to the boat's overall buoyancy (how will the boat sail with a flooded cockpit), AND how quickly the cockpit drains itself.
