A dock mates Cal 29's cockpit drain consists of a rubber plug in the stern. I was at the helm and he remarked that there was some water in the cockpit, and we should drain it when we were no longer under sail. I reached down with my bare foot and took the plug out, assuming that surely it was designed to drain while underway. He informed me that, in fact, I was letting the bay into the boat! I asked him what would happen if the boat got popped. He said that he has been in fairly large seas and has never been pooped. The boat has a large cockpit. I have always heard good things about Cal's and was impressed with the way the boat sailed. It felt much larger than it's 29 feet. For the life of me, I can't figure out way Cal would have used this method to drain a large cockpit. I mean, sure, you have have only one thru hull, but one good following wave would turn the large cockpit into a giant Jacuzzi! Can anyone enlighten me as to Cal's strategy?
