Leaks and solutions

Emily seems to leak, this is not a major leak but as we do not have a sea cock anywhere on the boat this must be from elsewhere.
The leak is not massive, about an inch per week and I intend to fit an automatic bilge pump powered by a solar charged battery (out of old box of goodies). However any clues? The hatch is nice and tight and the seal seems fine. The windows have been resealed recently.

I do have a loose stanchion that needs re-glassing from the back as it is very wobbly, however the bunk underneath this never seems wet? Any clues as to standard leaks would be welcomed as I like a dry boat with no need to resort to the bilge pump. At present the previous owner has a nice 1.5" plastic tube to the whale hand pump in the cockpit, before I crawl into the space under the cockpit is there an easy way of getting two pipes out to pump out?

I have many projects planned this winter and will take photos when the hands are warm enough.

Any deck fitting is prone to leak Check the Genny tracks . The main horse is prone to leak . Get someone to douse the boat with a bucket of water while you look inside with a torch.
If you only get an inch per week thats not too bad ,a sponge and bucket will be your best bet as bilge pumps will not suck any lower than pipe dia.

mine came from a loose stanchion fitting, which i resolved by filling the gap with araldite then when set skimming with gelcoat filler as epoxy reacts badly to UV and goes brittle, leak cured.
Have you looked under the bunk cushions as mine were dry but the water was running down the interior wall and under the cushion itself.
I would agree with Ron and as part of your winter refit consider checking and resealing all major deckfittings as seals do deteriorate.
Use siklaflex as opposed to silicone sealant as it forms a better seal

I was looking for a leak in Blue Myth also and after a while I figured out that it was rainwater comming in trough several deck fittings.
If that is the case the problem will become more difficult due to the balsa sandwich soaking the water and starting to disapear.
That'll be one of my winter projects: Injecting foam and venting the sandwich by drilling many holes from inside.

Leaks I have encountered so far:

- Ends of the main horse.
- Stanchion base (the one just aft of the mast). Lets in a bit of water when it rains, but quite a lot when it is underwater (which is more of a problem as this happens regularly).
- Through the pushpit. A far as I can tell it was getting in through some unused holes in the top of the pushpit and entering the hull through the hole with the stern light cable.
- From little holes in two cans of cider that I kept in the bilge for a few weeks. I suppose there must have been an electrolytic reaction with the steel plate. Fortunately, I kept the beer somewhere else and the cider was only for the crew.

bet the boat smelt nice................. mmmmmmmmmmmmmm the fragrance of Avalon!!!!!!!!!

There is a good piece in "This Old Boat" about drying out soaked balsa core , not the easiest job in the world.

Silly question have you done the taste test, this will establish if the water is Sea (salty) or rain ( fresh) .

Another area that i discovered a minor leak was where the "U" bolts pass through the deck that support the standing rigging. this was a simple fix, just slacken the nuts enough to give a gap between the deck and fitting plate, clean out old sealent, squirt in new, re tighten.... job done

Sounds like lots of places to check and seal, loose stanchion and lots of old holes will be the first to go along with a list of all the good ideas from people. The taste test would be a good idea and one that I would be happy to apply after leaking cider, not so easy at the moment as the boat is still on Windermere and thankfully for many in the North West this is still fresh water rather than salt. It is due to be moved to the sea in April so if not fixed by then should be able to then establish from above or below.

Many thanks to all for ideas, as I can't get to the boat this weekend any ideas about the 1.5" plastic tube to the whale hand pump in the cockpit, before I crawl into the space under the cockpit is there an easy way of getting another pipe out to pump out automatically? having nice crawled up under the cockpit still unsure of layout.

Stiff white plastic water pipe (domestic type)?
(still will not suck out shallower than dia of pipe)

Indeed stiff white domestic plumbing pipe, works well but would like to have a automated bilge pump just in case I can't get to her as frequently as I should.

I had a float switch and electric pump on the little wooden boat i have. To be safe I think I Would open a new exit in the stern and duplicate everything to avoid back flow. You need a good battery
to power these pumps over the weeks.Rember to put an anti syphon loop in.

Skykomish E29 says:

perhaps a solar panel would help to keep the battery topped up if the pump has to work regularly.
Having said that you would certainly have a serious problem if you needed to pump out that often

Hi all
On tabatha we have a hand bilge pump and an electric one with float switch and the pipes all connect on a 3 way joint with an anti syphon thingy and it all pops out of the same hole, and we have just fitted a solar panel battery charger just enough to keep the batt charged.

Tim
Am I right in thinking that the electric bilge pump ties into the outlet pipe on the hull side of the manual bilge pump? Any clues as to what the anti syphon thingy looks like or just a description?

I have the luxury of two batteries and two solar panels so intend to have one powering just the bilge and the second as the main navigation/radio battery, a switch will allow me to swap if one goes flat.
