Just curious: for those of you who keep your boats in the water, do you close the raw water intake seacocks when leaving the boat for a few days, or leave them open?

Always leave mine open. HVAC runs when I am away from the boat.

This is a no-brainer- CLOSED!
It's just not worth the potential consequences if a problem develops.

I close the mains and genny, but leave the a/c open -enabling the a/c to operate in the "dehumidify mode".
I inspect that hose frequently.

The only one I have is to supply water for the head to flush and it's a pain to get at, so I just leave it closed and we use water from the sink to flush...I also have insurance, but why put in a claim if you can avoid it?...

I leave mine open. The least of my worries is the boat sinking at the dock while I'm not there. That's what insurance is for (although I check the hoses and clamps to be sure of good condition). It's the boat sinking while I'm on it half way to Block Island that I worry about and I would have the seacocks open then anyway.

2 for mains, 1 for genset, 2 for water intake for heads and 2 for discharge.
Heck, I forgot the 1 for the A/C.

Interesting mix of 'open' and 'closed', mostly 'open' by the looks of things.

I have had my boat for only one season so I was interested in learning what others do. I kept the seacocks open all last season, then closed them after winterizing the engines. I opened them again after recommissioning in the spring and they've stayed that way (except while the sea strainers were being rebuilt).

The consensus seems to be to keep a close eye on hoses and clamps (to which I will add: sea strainer gaskets).

Thanks for all the responses.

Closed - when we bought the boat made sure all were easily accessable.

Two types of boaters - those who leave seacocks open and have not had a boat sink at the dock . . . yet! and those who close them. Why take the chance for such a simple thing?

if properly installed and inspected, hoses dont' fail! they will if they chaff against something. every hose should be double clamped but even if both clamps failed, hoses don't come off that easily off the barb! anyone who had to pull an air con pump for instance knows it's not that easy to get the hose off.

i am a lot more concerned about some "technician" having replaced a fitting with brass instead of bronze than a hose failing... or raw water hoses chaffing on the engine on a sterndrive (no sea cocks), or that wonderful mercruiser design where a bellows failure will sink the boat!

it all depends on the boat and how you use it. on a small boat with only a couple of seacocks in one spot that you use every 3 weeks, sure... why take a chance. On a larger boat with seacocks in different locations which you use every week, i woudn't worry.

Keep in mind that exercising the seacocks regularly will prevent them from becoming frozen open. This is yet another reason I close mine when leaving the boat for more than a day.

A dockmate had his boat go down from a failed intake hose a couple years ago. I learned a valuable lesson after seeing the mess it created. Closing them is very cheap insurance- even if they're difficult to reach (like mine). With poor access I can close 'em all in less then 1 minute. That's time well spent in my book.
As a reminder to myself I keep a note next to my ignition swithes "SEACOCKS CLOSED". Works every time!

I close it when leaving the boat. I'm embarrased to admit that I accidentally closed it when launching the boat this year. I had just rebuilt the raw water pump too. The impeller blew apart in about 15 seconds and the belt squealed to a halt. I was lucky enough to find another rebuild kit local but I paid through the nose for it.

I keep them closed when off the boat.

For those that can't reach the seacocks easily, a boat hook works well to reach them.

All open but the Purasan discharge. All hoses replaced in 2007 and doulble clamped. Pascal is correct try and pull off an AC hose or sanitation hose and you will find out they don't exactly slip off. As far as chaffing anywhere I thought there was the remote possibility of that happeneing a second split hose was placed overtop of the primary. I do excersize the seacocks 2 or 3 times a season or if servicing strainers.

"A dockmate had his boat go down from a failed intake hose a couple years ago"

what was the cause, how old was the hose, was there any sign of chaffing? Marine hose dont' just fail...

as others mentioned sea cocks need to be exercised monthly... i usually do a monthly round testing all sea cocks, bilge pumps, high water alarms and cleaning the strainers. it's a good habit to get into.

I keep the engine and AC seacocks open, the head (raw water) seacock closed.

The AC runs in dehumidify mode (or heat in the winter) and the engine intake is short and the engine end is above the waterline.

I operate the seacocks every now and then.

i leave mine open, however this might not be a good example for everyone to follow as my boat is behind my house and i check it every morning. if my boat were in a marina and i did'nt see it every day, i would leave them closed.

Don't know for sure but the boat in question was 'well used' and had been recently purchased. The new owner was an experienced boat owner but one of those guys who doesn't do regular PVM, and only fixes things after they break.
I suspect the offending intake hose was in poor shape BUT if he had been in the habit of closing the seacocks, his boat wouldn't have found the bottom in the slip.
