Really annoying leak – any ideas??? 

 

Hi all, ever since having Concerto I have had a really annoying leak and I have so far been unable to find it's source so I’m hoping someone else has a fix or an idea where this water is coming from.

 

The boat is generally very dry but when sailing and the boat heels I get water seeping out onto the floor, some seems to come from are area at the front of the engine, on the starboard side, possibly under the battery storage but the locker itself is dry.  Most of the water seems to work its way forward somehow and then come out of the small gap or join that is between the vertical locker front (to the starboard seat/berth) and the “slanty” bit of the cabin sole (sorry about the use of the word “slanty” but it was the best I can come up with).

 

Having had a load of work done last year on the boat (new tank, floor, toerails, etc I was hoping that the leak would disappear but it is still going and really annoying as it’s about a cup or two of water at times.  My only thought it that water is collecting somewhere when the boat is on its mooring and then when she heels over this water is released from where it is collecting.

 

So before my nice new floor becomes watermarked, any ideas???

I have the same. I think it gets into the closed area under the step/ foot rest under the chart table and then runs out at the correct heel.

The question is how is water getting there, possible from the grab rails fixings running over the headlining and dropping down in the quarter berth.

Polar Star had this problem but it wasn't cupfuls but buckets! Somehow water entered under the Quarter Berth ran around the battery box and spilled out through the joinery onto the floor by the Chart Table. Never did find the source!
I always suspect that the cockpit drains may be a source of leaks as on most boats they are simply bath outlets and its possible the sealant has perished and allows water to drop into the space below.
Any water getting into the headlining will tend to drop out somewhere also - quite often over the switch panel and down.
Not much help really but there are so many suspects ranging from the hull/deck joints to the grabrails and windows.
Have a go with a hose and see if you can replicate the problem.

I had similar on the Port side.
Cured by taking off toerail and scraping out any cracks that had opened up between deck moulding and hull, then pouring resin into the slots this made.
One of these took a lot of resin.   It goes into voids between deck and hull, and comes out whereever.
Test for this is: does theboat stay dry when you do not heal so toerail goes under.  (Rain will not enter by this route because cracks are in top)
The removal job in required area was surprisingly easy.
No problem since.

Thanks for all the responses while I have been away sailing this week – great timing on the weather!

 

St Paddy – I’m pleased it’s not just us.  As you say the question is how is it getting there.   Grab rails on deck are due for renewal soon so perhaps that will help.

 

Colin – It’s not the windows as they have all been replaced so should be ok, I have checked the cockpit drains and while I may replace they look ok and any water leak would end up in the bilge not on the floor (I have just spent some time in the cockpit locker to check this).   Difficult to replicate the problem as the water only appears when heeled over and when heeling over I’m normally involved in sailing rather that leak spotting – perhaps I could try anchoring from the masthead J

 

Richard – Thanks for the suggestion but I have just had all the toerails and taffrail replaced, the join was pretty sound on concerto just a couple of small cracks that were filled before refitting the new wood.  

 

I think the problem is that (rain?) water is getting trapped somewhere and then comes out when the boat heels over.  Most annoying.

 

Thanks again, keep the suggestions coming!

George,
 
I think the only area where the woodwork isn't bonded to the hull is the open locker under and outboard of the chart table - I only know this because the piece of timber on the slanty bit under the chart table came adrift last year revailing all sorts of screws and split pins etc that had been dropped down there over the years. I'd try sealing this and any other non bonded areas and getting the water to stay in the locker / under the berth where you can at least contain it and bail it out.
Also be brave and taste test it - salt or fresh?
After thought - if fresh, is the hatch on your water tank leaking? Do you still get this if you sail with an empty tank?
Hope you find it soon.

Hi Paul,

Thanks for the suggestion, I have checked the open locker under the chart table and the sides of this all appear bonded in so any water would (and used to before I fitted new windows) collect, so this doesn’t appear to be part of the route for the water.  There is a step for the navigators feet that you can not get under or into but I have drilled a couple of small holes and no water has come out of this so I’m assuming it drains into the bilge.

 

I’m confident that it is not the water tank as I have had this problem ever since owning the boat and I had Rogers fit a new stainless tank and floor last year.

 

I will man-up and do the taste test again next time I sail.

George,
 
If all the lockers are bonded, then it suggests it's not coming down from above, but either up from below or fore / aft. Depending how your water / gas / diesel pipes pipes run, there's a route from the cockpit locker through the galley to the top of the water tank. Another possibility is the outer two bolts for the cabin table, which on Waratah are through hull bolts. These might leak with a bit of motion when sailing and then run between the timber and grp and come out on the cabin sole. (Since we had osmosis treated and retreated when the first coating failed, the whole hull below the water line was given an additional layer of woven rovings epoxied on, prior to new epoxy coating. Now all the through hull fixings are behind this layer - they'll never leak, but I hope I never need to replace them!)

I had this problem again with mine this week during our holiday.

The drain holes under the engine tray had blocked so water was collecting under the stern gland and under the sole from there it  spilled over around the engine beds and found its way onto the saloon floor. It was rough and the motion horrid.

I do get a small amount of water collecting just under the stern gland and another small anout of water under the gearbox coupling, both of these overflow into the GRP engine moulding where I bail it out every now and then.   Its possible this could work it's way forward when the boat is well over but unlikly I would have thought. 
The drain hole in the bottom of the large cockpit locker is blocked (or was never drilled out fully when the boat was built).  I suppose it is possible that water is draining into a void from the cockpit locker and then getting trapped or working it's way forward
 
Would I be correct in thinking that the cockpit locker drain should come out in the bilge just under the engine moulding?
