Re: Closing seacocks

I close my 3 seacocks every time I leave the boat (usually for a week). There are still a number of thru-hulls w/o seacocks: rudder stuffing box, shaft stuffing box, two cockpit scuppers, knotmeter wheel. I would imagine a good drip would sink most boats in a week.

Re: Closing seacocks

I close all seacocks, except the 2 cockpit drains, when I leave the boat unattended. To avoid the possibility of starting the engine without raw water open, I leave the key looped on the raw water seacock.

Re: Closing seacocks

I close all except the two cockpit drain valves (need to stay open to drain rain water).

I also have this remote monitor which will call my cell phone for high bilge water or low battery voltage. The company has been bought by Mcdermott Light and Signal. Gives me peace of mind if away from boat. Figure if I get high water alarm I can get to boat and solve problem before she sinks.
Boatsense Solutions
The unit is now monitored by:
Marine Navigation Lights by McDermott
Contact Mcdermott Light if you are interested in purchasing.

This unit has multiple normal open or normal closed contacts- you can wire these as an intruder alarm, smoke alarm, low temp, high temp or whatever you like. The unit will text message of the abnormal condition.

Re: Closing seacocks

I don't close mine during the sailing season.

I'm on the boat most of the day almost every day. I carefully inspect the hoses and cycle the valves quarterly. That's working for me.
If it don't need to be below waterline eliminate it, if it does, then locate near a hatch so you can close it.

Re: Closing seacocks

A friends Hunter has the best seacock setup I've seen. The head, galley and engine are all clustered around the companionway so under the galley sole is a pit with all the seacocks, strainer etc. clustered in one place, labelled, plugs wired to each and everything right at hand - very slick.

Re: Closing seacocks

I close all 6 every time I leave the boat--even if it's for just a couple hours.

Re: Closing seacocks

I close them all except the cockpit drains, bilge pumps and the exhaust valve (above waterline). Like others have said we leave the ignition key on the raw water inlet valve.

Re: Closing seacocks

I closed all 7 every time I left the boat if I wanted peace of mind ashore. I replaced the cockpit drain thru-hulls, seacocks and hoses when I bought the boat knowing that they would always remain open. I usually closed the engine, head intake & discharge if not being used when ON the boat. Why not? The alternative could really suck.
