This is a video of a repair I made to one of my early 1970′s sunfish that had a split in the hull underneath the cockpit. For me this was a first time fiberglass repair. Much of the technique was garnered from youtube videos by individuals and product manufacturers, without whom this fix would have been much more trying. I offer my experience to add to the body of material out there.

This episode is the third of a series about the recostruction and restoration of a 29 foot Bayliner Cabin Cruiser. It covers from the making and installation of the custom fish box to the redesign and reconstruction of the engine compartment, using fiberglass reinforced honeycomb panels in setd of plywood.

Repairing collision damage on a Laser sailboat. The Laser is a lightweight boat that’s decked over, so most repairs have to be made from the outside. I used epoxy for the structural repair because its stiffer and bonds better to the original polyester layup. I switched to polyester for the filler (Bondo) and gelcoat. Many people warn not to do this. I find it works fine as long as the epoxy has cured at least a week, and has been thoroughly cleaned of amine blush and well sanded. These techniques can be used on any fiberglass repair where only one side is accessible. Be sure to extend the bonding area well outside of the original damage. This repair was done over 3 weekends. Don’t despair – fix that boat and get out there again!
