I have a continuing problem on our 385 of water dripping through the saloon ceiling lights, presumably a result of water ingress.  I can not find the source - it could be around the mast, from the self-tacking track or from the pipe through which the electrical cables enter the coachroof.  Has anyone had this problem?

I have had the self-tacking track off and resealed the screw holes with Sikaflex.

Any pointers would be appreciated.

Not sure if the 385 is like the 370 with a vent in the galley area.  The seal failed on that and I had leakage.  Took it off and re-seated with new sealant and not had a problem since.

We had a similar water ingress problem on our 415 which resulted in sea water (never rain water) slopping about on the port side shelf above the bunk in the forward cabin.

We eventually traced the problem to the black corrugated sleeve that takes the wiring from the mast into the swan neck fitting. The sleeve is slit along its length, the fitting is on the port side of the mast and when we were well heeled on starboard tack with green water coming over the foredeck, some of the water found its way into the sleeve, down into the main cabin roof and then downhill into the forward cabin roof and shelf.

You can test easily for this: remove the saloon ceiling covers below the mast and play a hose on the sleeve.

Solution: tape up the corrugated sleeve but leave a small drain hole at the lowest point.

Hope this works for you.

Not sure about your 385 but my 400 has fiberglass panels that screw down over the top of all of the lines running from the mast back to cockpit clutches.

There are multiple screws on each panel that screw into the deck proper beneath the panel, if not sealed with decent dollop of sealer, water will gain access into the cabin lining through these.

Same here on Rubato, 2007 400e. Anything that screws into the top deck has the potential for leaking and Hanse doesn't do a consistent job of sealing these screws.

Had problems with water coming in through the base of the tube for the mast wiring. Took some serious rain for it to come trough, and only found the leak while inspecting during the rain. On a 385. The sealant was not appropriately applied. Quick fix. 

The tube has a flat base, and could clearly have been designed more intelligently, changing it however, would involve some serious issues with threading the wires, so it was fixed with a generous application of Sika.

All the penetration points, including from the self-tacker track, can easily be inspected by removing the two small plastic hatches in the inside saloon roof below the mast foot.

We have the same issue on our 320 and have traced it to the swan neck for the cables running from the mast.

As said in a post above taping it up has helped

Hi - I've found the swan neck to be a potential source of (sea) water ingress on both my Hanse's (400 & 455).

I've stuffed the outside aperture with (grand) children's plasticine. I don't think they've missed it Wink and it certainly does the job.
