Re: Another Venture 17 keel repair question Another Venture 17 keel repair thread

Thanks for the replies. I actually have Evercoat reinforced fiberglass filler on hand but was concerned that it might absorb water even after applying epoxy and gel coat over it. Here's an overall view of the keel out of the boat. The cracks are hidden in the photo as they are in front (to the right in the photo) of the wood uprights.

Here's the crack on the port side (facing the wall in the overview photo above). Again the crack is in front of the uprights.

And here's The starboard side. The crack goes up and over back to the port side. All of this appears to have started when the keel was hit by the trailer axle (previous owner damage)

Damage from the axle. It's located about 1/2 front to back along the underside in the overview photo. You can't see it as it faces toward the floor.

Yes, that's a hole. It 'feels like' plywood in there.

Doesnít look like the axle did the damageómore like someone hit a rock. The hidden damage could be substantial. Maybe itís time to check out a new swing keel before opening what could be a can of worms.

BTW, Bondo is not an acceptable material for underwater use. I ran into a keel ding repaired with Bondo by the PO of a boat I had many years ago. It had absorbed water and was not a viable patchóand that was not a structural repair; just a filler for missing fiberglass.

Ditto on the Automotive/Home Store Bondo as it has talcum powder in it and not polyester or glass.

Talc is a soft clay that absorbs water and should not be used on boats except inside your gloves and such to prevent chafing. Talc definitely should not be used to build up structure below the water line yet some builders have even used shredded/chopped/ground up rags in their chopper guns instead of glass when they build their hulls.

Ok. So Evercoat fiberglass reinforced filler in a no go even though it claims to be waterproof. I'll stay with strictly marine grade stuff that's noted as being below waterline usable. I appreciate all of the input.

Their Marine Grade products are good however you'd have to double check about which to use below the water line.
Marine

With the extent of your damage though get into it quickly while you still have the option of buying a replacement. Before cutting into the old one you may want to scribe some of its contours on cardboard or even make a plaster mold of a section of it. Be sure to record critical measurements on length, etc too in case you need to cut out and replace rotted steel by welding in new sections.

You mention not laying it on its side due to bowing concerns. If its bowing then its more likely that the steel/structure has been compromised to a degree. I have not seen many centerboards that would bow sideways under their own weight yet that did not need replacement in my limited experience which is mostly on 12 to 25 foot boats.

Both the Everglass and Kitty hair claim to be waterproof and are in the marine catalog. I definitely will take careful measurements and a profile before I start. Not only does it have to fit correctly but it also needs proper hydrofoil shape. The warping concern is just my Engineering background getting the best of me. Finding a good replacement keel that doesn't require shipping has been a challenge to say the least. I am watching expenditures to keep from dumping huge amounts of cash into it. Therefore I'll work with what I have. Doing the actual work isn't a huge challenge for me; I just need to have a clear plan drawn up first.

Thanks again!

Re: Another Venture 17 keel repair question Another Venture 17 keel repair thread

After searching the Internet and calling BWY, a replacement keel is unavailable. So surgery started. As expected, the wood fillers were completely rotted and the steel bar has significant scale. I cut one side open, stripped the fiberglass/epoxy, and then popped the assembly out of the lower half. The lead weights are bolted to the steel so removal wasn't an issue. Now I need to take a trip over to the steel supplier and rummage through the scrap shed. I'm on the fence if I should get a bigger piece of steel to eliminate the wood fillers but I think that'll add too much weight. Any thoughts on something other than wood? Plastic decking aka trex type material??? If I do use wood, I thought I'd use oak. Marine ply isn't readily available here.

I can only add one photo at a time so pardon the multiple posts
