I recently had extensive work done on the keel after the cable broke and swung down punching hole in forward part of trunk. That has all been repaired and looks really good. Boat was placed in the water to check for leaks where repair was done and everything was ok. I has the boat put back in the water this past week. I motored from the drop in area to my slip, tied her up and started looking over the boat. In the area under the companion way stairs,just forward of the bilge pump water was seeping in. HUGH DISAPPOINTMENT, since the boats has been out of the water since last april. I had to bring the boat back out of the water and place it in the yard again. Any ideas as to where this water could be coming in. The fiberglass guy who did the initial trunk repair says he may have to cut out a section of the floor near the galley area to see what is going on. Does this sound a little excesive ? Any ideas ?

I agree with Dave, check all around the area where the keel enters/exits the boat. It may just need a hose replacement.

Thanks, I will check the clamps first. Yes I did remove the storage covers and used a towel to soak up the water but continued to trickle in.

It was still seeping while tied up in the slip! Some people report water up the keel cable tube if backing a long way or quickly. Any through hulls in the area?

Obviously it's essential to determine exactly where the water is coming through the hull. I strongly suggest getting this figured out while the boat is in the water. (Unless the leak threatens to sink the boat.) If the problem seems to be located under the cabin sole, then yes, some exploratory surgery may be required.

One way to get a look into that inaccessible area is to cut away the hull to liner tabbing at the aft end of the cabin sole. This involves working inside the storage space under the quarter berth and/or under the galley sink. This will require good lighting, the right tools, and a degree of contortion. If using power tools, remember to protect your eyes and lungs from the resulting cloud of fiberglass dust.

When replacing the tabbing, I used two layers of woven roving and epoxy resin. Be sure to clean bonding surfaces by sanding or grinding and scrubbing with acetone or similar to assure good secondary mechanical bond.

Being able to show us good quality digital photos will help us help you.

The cable thru hull and the sink/icebox through hull will both drain to that area if leaking, but so will anything aft, including the cockpit, scuppers, and coamings. With the boat out of the water, you could fill the bilge with water and check for leaks low in the bilge. You can also dust the bilge with line chalk (Home Depot, etc.) and go back in the water before cutting and ripping.
