A couple of weeks ago the Marina where my boat is was pounded by wind and waves (freak direction). Anyway my boat must have come out of the water and when it returned, it caught the bow rail on the dock ripping it off the boat. Fiberglass and all. Question is since it is behind where the forstay attaches is there a structural problem or just cosmetic. Thanks, Bill

Bill,

I'm not sure by your desciption, but it sounds like the bolts on one of the attachment points pulled through the deck. If so, you just need to fill the holes, redrill, and reinstall the bracket. I would put larger backing plates under the deck however. Catalina originally used washers, which is fine for normal stresses, but as you found out, will not hold up under unusual circumstances.

Check the archives. There are many examples of this repair, many with pictures.

Bill,

I've repaired this exact damage on my 1979 C-25. On my boat, the fwd pulpit stanchions ripped out of the deck, leaving ragged holes through the deck and core about the diameter of the stanchion base. Previous owner had shoddy repair done, which resulted in further damage to foredeck core.

Working through the anchor locker opening, I removed all previous plywood core ahead of anchor locker opening. Original core seemed to be 3/8" plywood. I cut two layers of 1/4" plywood to fit that area. I applied a layer of fiberglass to the bottom of each triangle of new plywood. Just before installing, I saturated the top and edges of the plywood with epoxy resin. Using a huge volume of thickened epoxy filler, I installed the new core one layer at a time.

I think I used a small bottle jack sitting on a piece of plywood inside the anchor locker to force the new core to conform to the slight crown of the deck. (Most any means of producing upward force would work as well. Wooden shims and wedges come to mind. Just be sure to dry-fit all this before mixing that huge batch of filler!) Once I had squeeze-out all around, I shot a few self-tapping screws down through the foredeck into the new core as temporary clamps while the epoxy cured.

Once the damaged core was replaced, I ground out and patched the exterior damage to the fiberglass with epoxy mixed with short strands of fiberglass. What form of fiberglass filler to use depends on the size of the hole being repaired.

Finally, after restoring (improving, really) the strength of the foredeck, and reestablishing the shape of the exterior surface, I refinished the repaired area with gelcoat.

This was about two to four days work. (<i>Some of you may notice similarities between this straight forward repair, and the work needed to salvage a boat damaged by an early style forestay deck fitting having been overloaded...</i>)
