Oceanis 423 Saltwater Leaking into Aft Cabins

[cherikita]

Hi
We have noticed a small amount of salt water leaking in to both aft cabin's wooden cupboards. It only happens when we are sailing. Has anyone had similar issues? Any idea what may be causing this and how to fix?

Thank you!

It only happen on one tack, and with the rail in the water?

[cherikita]

It happens on both tacks in the same location. We checked the drains on the deck (by hosing fresh water) and it is not coming in from there.

Try to sail on the tack where the cupboards are, hard on the wind , with a flaslight in hand aim to the hull deck joint and any hose running at that area, toilet discharge , tanks vents etc... i have a similar isue with a hull deck joint in a old Bene.... also check if there is any deck gear on top, winches, cleats, etc... and see if they are watertight.

Hi, I suggest that you join the Yahoo Group for Oceanis 423 owners. It has a large number of very well informed owners who have a vast knowledge of anything to do with the B423.

If you have the usual Beneteau lewmar portlights with the horizontal seam in the center of the frame on each side you may need to clean out the caulk and recaulk them. I had this problem. The lenses did not leak but the frame itself was letting water in.

Not sure if the 423 is the same as the 473.... but I had a insidious leak that turned out to be in the drain tube from the transom locker to the thru-hull..... learned later than it is a known problem.

Here is a blog that discusses the issue:

Looking at the diagram and layout the seal on those rear windows would have to be the first item to check. I have however noticed that water runs down the deck of my Oceanis and that area is a seemingly natural drain point so is it possible you have a leaky deck/hull seam or even the cleat/stanchion fittings?

Another consideration here (assuming your Oceanis is similar to my 50) is that there is a ledge at ceiling level in the rear cabins where cables run from your instruments in the cockpit to the nav table so there is a possibility that water is getting in around a stanchion/cleat fitting further back or where the rear winches or lockers are and running along this ledge.

Just a few thoughts, good luck
