Hi,
Looking for advice on whether a gas locker drain to atmosphere needs a seacock,gatevalve,plastic valve or no valve at all;given that it should be at least 75mm above waterlevel. Also plastic or bronze skin fitting?
Thanks in anticipation of usual helpful assistance.
Harry.
 
if its above sea level at all times - I dont see he need for a seacock - and a plastic skin fitting will be ok - I would not want a seacock on mine - if its closed you have no drain - and if it ever gets under water again you have no drain
 
Seconded. Just an open hole above the water line - nothing to go wrong. However, on my boat the following seas wash the bottles and rust them. Suggestion is to varnish the bottles before installing them!
 
Mine exits on the boot topping, a couple of inches above the waterline. I don't have a seacock on it in case I forgot to open it when opening the bottle valve. If the hose connecting it to the locker failed I could easily reach over the side and block the hole with a tapered wooden plug.
 
mine doesn't have a valve. Though its not well sited. The hole is about 5cm above the locker floor, so when heeled, water comes in but then the doesn't drain out properly, so I'm always sponging the thing dry to get rid of the last few cms of standing water.

Off hand I do not remember anything about valves on the drain. Inadvisable I would have thought! No point in the drain if you shut a valve on it!

Note that the drain does not have to be from the very bottom of the gas locker provided the free space below it is filled. That's covered in the BSS and might solve aproblem in a small boat where you cannot get the locker as far above the waterline as you would like.
 
I used a plastic skin fitting approx 75cm above the waterline with a fall from the gas locker and 19mm ID plastic hose. /forums/images/graemlins/cool.gif
 
you could put a flap on theskin fitting that stands ajar so it still drains freely, but closes when water tries to go in. alternatively, get a Taylors <runs for cover>

I,m just nervous about having any 'unshuttable' holes near the waterline, I feel the last thing I need in an emergency, is to be hunting for the appropriate 'bung'! Bill.

[/ QUOTE ] Yes and perhaps we should remember that the Boat Safety Scheme is really written for inland waterways craft where perhaps there is not quite as big a hazard with an "unshuttable" hole as there is with a boat at sea. If you are on a canal you can always go to the bank and step off!

Mind you I've got one unshuttable hole well below the waterline, about as far below as it's possible to get in fact . Its got the galley sink on the top of it and after thirty years i've stopped feeling nervous about it.

You are made of sterner stuff than me Vic, saw a boat that had taken the ground and heeled right over, in Muros, Galicia, no one aboard, half fill through the sink drain! Bill.
 
If you are that deep in the water that a small hole in the hull is letting even more water in, then there must be a lot of water already in the boat!! Mine has no valve and never will have - not had a drop in during the 15 years I have owned it.

Edit:
KBT, that's the beauty of twin keels, they don't usually fall over!

[/ QUOTE ] Galley sink drain on a Pentland? Are you sure, pretty sure theres a gate valve on a Berwick (Also on heads sink drain, and engine cooling water, but seacocks on the cockpit drains and heads inlet and outlet.) IIRC there is a simple cock on the gas locker drain (but thats such a stupidly small diameter that it might just as well not be there, especially with front opening non-gastight door.)
