Reply To: Keel protection options

Yes Garry Mike is right most HTs and other cats simply cut plywood to the shape of the underside of the keel and bond it on with sikkaflex. There is no drilling through so if the whole thing should fall off (unlikely) then there is no damage, you are just back to the original build. If you want to be really clever you can fibreglass over the whole thing once it is in place and set..
The alternative is to fabricate a fibreglass add on shoe and sikkaflex that on in the same manner. Wood is probably cheaper and easier, but the glass one might last longer.
