Re: Closing seacocks

I once worked on a boat, which had the head sink drain led thru a slightly flattened ss tube , under the head seat, into the head bowl. One thru hull eliminated. There are many such innovative options , Finding them is great sport.

Re: Closing seacocks

Let's see... 4 bathrooms at 4 seacocks each, galley sink, washdown pump, engine, crew's quarters toilet (uninstalled), crew's quarter's sink, prop shaft. That's 22 below the waterline.

3 bilge pump outlets, engine exhaust, swim platform locker.. those are above the water line.

Many of the inlets are verticle and at or near the water line at the top of the seacocks.

I'm putting a bilge-on alarm on the onboard webcam. So at least I'll get an email every time the bilge pump goes on. (I actually brought the webcam home tonight to bring it to a tech store for the right plug for the alarm connection.) I have a driod, so I usually see emails pretty quickly.

Re: Closing seacocks

Yes. always, except the sink and cockpit drain. Both hard to get to both are above waterline. The boat next to me would have had a sad day tomorrow if we hadn't opened his engine compartment while looking at the the zincs he lost after 3 weeks in the water. I noticed his bilge pump was cycling, all afternoon. Hose was fine, engine was leaking, small plastic plug was broken off below the o ring. He was not connected to shore power so batteries only. 2 very expensive engines, batteries and an expensive generator down there. He never closed the seacock before, had to pry it shut with a wrench.

EDIT: After Brent's comment one thing about my head finally(sort of) makes sense. The previous owner observed the sink drain hose runs to the deck, and nowhere else. The rubber hose is just the right length to drain into the head, so long as you are willing to hang onto it. The SS tube makes more sense, I'll try that when I get to fixing the head.
