Beneteau 461 water not draining to bilge

[TJReid]

Hi everyone,

First timer here!

I’m TJ, and I recently purchased XTC, a 1998 Beneteau Oceanis 461, three-cabin/three-head version.

I’m currently trying to solve a drainage issue and would appreciate any help, experience, photos, or factory drawings other 461 owners may have.

On XTC, I have a section of the molded structural grid near the starboard aft head/refrigerator area that traps water and does not appear to have a limber/drain hole connecting it to the adjacent bilge compartments. Water collects in this section with no obvious path to the main bilge/sump.
I’ve found reports from other Beneteau 461 owners of factory drain/limber holes apparently being omitted during construction.

Before I attempt to drill anything, I would really like to determine how Beneteau originally intended this area to drain.
Does anyone with a 461/463 have access to this area of their boat? If so, I would greatly appreciate:

• Photos of the bilge/structural grid around the starboard aft head and refrigerator
• Photos showing any limber or drain holes between the molded grid compartments
• Beneteau structural grid, hull liner, bilge or drainage drawings
• Information on the location and approximate size of the factory drain holes
• Experience with trapped water or missing limber holes on a 461/463

If anyone has run into this issue any help would be greatly appreciated

Thanks,
TJ

Sorry, but I don't have a Bene 461. I'd certainly like to but don't.

Can you identify the source of the water entering this area of the
grid ?

It was from the sink. The leak is fixed but I just don't want anything else to cause the same issue.

It was from the sink.

I suspect Beneteau did not supply a limber hole because they did not feel it was required. The damaged sink drain is not considered a normal source of water ingress, therefore the owner is expected to repair it.

If the water is coming from a sink drain, you definitely don't want it in the bilge. Imagine the residue from washing dishes with the grease, oils, and other stuff ending up in the bilge rotting away and reaching places that can't be easily cleaned.

TJ, you do NOT have a drainage issue. You DO have a leak / maintenance issue. We appreciate the care and detail you put into your original post, it's not often that one that comprehensive is provided. But your resultant admission of the actual water source, only when prodded to tell us, has us perplexed as to why you'd request such details for simply identifying and fixing a basic maintenance item. We wish you well in finding all that other very useful and helpful boat-specific information for your future use, such as for a real problem.
