V34/Frances 34 Hull/Deck Joint Leaks

Hello,

I have leaks from the hull deck joint both sides in the area of the forecabin.  My boat is a Frances 34 Pilothouse with the standard teak toe rail.

It doesn't manifest itself until either the decks are awash or I am shipping water over the bows and I am pretty certain it isn't coming from the chain locker or bowsprit. 

Applying silicone in under the toe rail both sides frankly isn't the solution, so I suppose the only real solution is toe rail off and reseal/fibreglass etc.

I suspect many V34s suffer this way so I am hoping someone has experience of a solution.  Any advice appreciated.

Best wishes

Re: V34/Frances 34 Hull/Deck Joint Leaks

John,
I read your note after a particularly demanding bash through the "Channel Chop" around Dungeness recently.  We have a similar problem on ALBERTINE our Frances 34.  I like you have tried all the obvious causes including a new bowsprit and re-seating the pulpit.  The problem does not occur in any amount of rain or hose washing but only with "green water" over the bow.  I believe the water is forced into the chain locker through the windlass and forms a light spray which comes into to contact with the outer glass fibre skin, as there is no lining in the chain locker.  The boat motion then moves the water film aft and into the area where the forepeak lamination of wood and laminate comes into contact with the outer glass fibre. The water then finds its way down behind the lamination and manifests itself under the forepeak mattresses.   We have tried just about everything to solve the problem but to date no solution has been found other that to prop up the mattresses and place a towel to absorb the dampness.  Keeping a boat dry in heavy weather is one of the oldest problems facing us all.  We are now back in the Hamble and all is dry and shipshape and will remain so until our next session in very heavy weather.

Hello Jon,

that is the theory I adopted as principal cause.  I have used an endoscope to check what I can see of the hull deck joint and it all looks fine, reinforcing your theory.

To monitor it, I have taken off the trim panel on starboard side above the berth shelf and will check for ingress after green stuff over the bows.

In the meantime, I have lined the berths with thick plastic sheet to protect mattresses.  Dinghy paddles beneath mattresses help keep them clear too.

I'll keep you posted.

Goss sends his regards.

Re: V34/Frances 34 Hull/Deck Joint Leaks

Our boat is a 30 but this problem seems common to all Victorias or perhaps all boats of a similar vintage. We have had leaks for years running down the inside of the hull - you know where the water ends up but not where it comes in. Never more than than a few drops but nonetheless annoying.

Last year we had the teak toe rail replaced (at considerable expense). Once removed it was clear that water had been sitting under the toe rail but still not obvious how  it was getting inside the hull. The original bedding material was hard and brittle. There were tiny hairline cracks around some of the screw fittings. There were no signs that the hull/deck joint had moved but the sealant between the two looked doubtful.

All now back together and looking very smart and so far no leaks.

Re: V34/Frances 34 Hull/Deck Joint Leaks

I too have doubts about the integrety of the hull-deck joint in our V34 and only when we've been sailing hard on the wind. No amount of hose work duplicates it. Net result,  salt water on the forward bunks, wet under the toe rail and drips from the leading edge of the trim below and forward of the front portlight.

We've had leaks from elsewhere, too. The deck drains leaked badly but they are sorted though getting to the starboard drain was tricky as it's panelled in. We rebedded all the portlights recently and don't seem to have admitted any fresh water from recent heavy rains finding it's way down to the edge of the cabin sole. It may be too early to be sure, but I'm not surprised given the condition of the sealant when we took them out for inspection. Another problem was delamination between the coachroof and the cabin lining which we sealed before reassembly. Any water that got past the sealant could get into the boat unseen and appear where gravity and tracking allowed.
