Beneteau 461 Sydney, Australia
I have a 1998 Beneteau 461 and have owned it since new. Over the past few year, following heavy driving rain, water has been accumulating on the port side under the water tank. I believe most of this water has been coming in through the mast but it does not drain to the bilge. Some water may also be getting in from the Lazarette. I have pumped out up to about 12 litres after prolonged rainfall. The water is fresh.

The boat is reasonably well weighted although slightly heavier to port. It is most likely that something is blocking the flow path to the bilge but I can not access this area without major work.

I am interested to know if any other 461 or similar boat has any idea of the possible cause and location of this problem and any effective solutions. Is there a chemical I could use to unblock the flow path or would it be best to try a high pressure hose?

There is access to the top side of the hull under the centre salon seat. This is where I can pump the water out.

Any ideas would be greatly appreciated

Beneteau 33.7 Port Jefferson
We seem to have a similar problem. Our Beneteau First 33.7 is collecting fresh water
in the forward cabin which is not draining to the main salon bilge where it could be
pumped out. We also think it is coming from the track in the mast. We are going to try clearing the blockage with a power washer next week. There seems to be no way to clear the blockage with a metal snake because it must curve or angle right after the water enters the little hole leading aft. We'll let you know how it works.

Hi folks. I have a 461 with a lazarette which will not drain into the bilge. Any idea where it discharges into the bilge so I can clear it from the other end. Access is poor in the lazarette due to a genset in the way. Thanks heaps.

Andrew.
