Food for Thought
Yes, I am also appalled at Bob's reaction to my answer. But I consider myself a rather accurate information giver. And it's not my demeanor to mislead anybody. So I 'googled' for ABYC standards regarding cockpit drains and this is what I found in an article written for Chesapeake Bay Magazine in January of 2003. The answer is not definitive regarding ABYC standards since the standards may only be voluntary and not regulatory. And this may not be authoratative, but it is printed in a reputable magazine. Again, IT IS ONLY AN OPINION. I have witheld the author's name so that he will not be maligned by individuals on this board. ...Cockpit Drains:"What, you ask, can possibly go wrong with cockpit drains? The water disappears and everybody’s happy, right? Maybe. Let’s say your boat was built in 1980. Chances are the cockpit drain hoses are original, meaning the safety of you and your vessel hinges on a 23-year-old piece of hose.First you should visually inspect the entire system, from cockpit drain to discharge through-hull, noting any leaks, splits or cracks in the hose or fittings. Is the hose double clamped with stainless steel clamps at both ends, and are seacocks used? The answer to both questions should be yes. Some boatbuilders, if they think the discharges are high enough above the waterline, omit seacocks on discharge through-hulls. You should verify that these remain well above the water all the time (whether heeling or planing, for instance), and install seacocks if you have any doubts. Inspect all hoses carefully for signs of deterioration, kinks or chafing. In colder climes look for hoses to be split or pushed off hose barbs, which can be caused by expansion and contraction during the freeze and thaw cycles. Heat and vibration can generate similar problems."...Now, I ask, would I put my integrity in jeopardy with bad information? It seems logical to me to use seacocks where they will do some good. There have been some good points made here on this post that show the pros and cons of having seacocks on cockpit drains. But, let me say that the answer could swing both ways and that it becomes an individual decision to put them on, or open them, or leave them closed. But, my feeling is that ANY thru-hull, either above or especially if it is below (or could go below from weight, etc.) the water line, should have a seacock.If any newbie is reading this thread, then he/she has something to base their decision upon. I also feel, that in the future, if I answer a question, I don't have to document the reason I responded as I did. BTW, the boat that I said could have sunk was a classic 1978 Pearson 35. Wether the PO put seacocks onto the cockpit drains, or not, I don't know. But the seacock/thru-hulls were located where the could not easily be visually checked. But they were accessible by any human being and could have/should have been checked - but hadn't been in a long while.
