Seacocks

Do you close all your seacocks every time you leave your boat? KJ

No...but my seacocks, clamps and hoses are only 2 years old....I got rid of 5 seacocks and now just have 4.....

Even IF a hose totally separated from the seacock...it would take many hours before it became critical and started covering any significant system.... because even 1/2 my bilge pumping capacity would slow the accumulation down to several hundred gallons an hour. My boat could easily take on 1000 gallons before I would be really nervous.

I usually worry more about forgetting to turn the fresh water off than the seacocks/hoses.

It's a good idea to close the, it keeps the operating smoothly and you always know the work. I always close them off when I leave, naturally if I leave the sir com on I leave that one open.

I understood common practice is: sailboats do, powerboats don`t. For me:
Short time absence, going ashore, boat hopping etc, no.
Prolonged absence, yes, definitely, all closed.

I always close the three below the water line but the half dozen or so drains just above the line, no.

I always close all five seacocks when I leave the boat and "go home"

If I leave the boat to just go ashore, wether anchored or docked I do not close the seacocks.

I suppose that "going home" really means that I'll be off the boat overnight or longer.

When I close the seacocks I put a piece of paper with a "closed seacocks" notice on the helm with the ignition keys poking through the paper, and a similar note at the generator control. Each note has the date the seacocks were closed.

No vote here. I exercise them prior to every outing though as part of my engine check.

Yup, pretty much, at least the ones below the waterline.

I close mine whenever I leave overnight and tag the keys.

One question though. I don't have seacocks on my above water thruhulls. It sounds like others do. Is that to guard against the possibility of additional leakage if the the vessel takes on water and submerges the higher thruhulls? Or is there another risk?

I close the three below the waterline when we leave the boat at the berth, but not while we are out. However, the engine intake sea cock is right beside the engine, and hard to reach anyway, without lifting floor and hunkering beside a hot engine. So, I set up a handle extension, and linked a long metal rod to the end of the extended handle forward, with a knob on it, so I can reach it from the forward engine room hatch, which is easy to get to. However, every now and then the damn handle works it's way off the seacock, always when it's the end of a days run, and if that happens I just say bugger it, I'm not getting in there next to the hot engine to turn it off...it'll keep until I'm back down there when the engine is cold. If your hoses and clips are good, it's no big deal, really. It's mainly an insurance thing.

Worth doing for no other reason than getting the seacocks exercised.

If we are staying on the boat they are open, when we leave the boat they are closed.

No. I do exercise them periodically, but they remain open at all times unless I'm performing maintenance that requires them closed. When they're closed, I place a prominent flag on the keys alerting me that they are closed.

Most of mine are usually kept open except for the black-water outlet.
