If your swim platform is experiencing water penetration, a repair or even a rebuild could be in your near future. We’ll show you how to measure the damage, and perform a successful repair that will last for years to come.
When you need to repair your fiberglass boat’s balsa core but don’t have any replacement core material on hand, what can you use as an alternative? I tested some different replacement core options to see how they’d perform in flexibility and strength alongside original balsa core in a fiberglass laminate. Continue reading →
My friend Chris bought a 33′ fiberglass sailboat, a Cal 33, to use as his family cruiser. Because it was an older boat, he knew he had a few projects ahead—including drying out the wet rudder. Here in Michigan, we haul our boats out of the water for the winter and it gives us a chance to do repairs and inspect under the waterline. Continue reading →

I received a call from a friend of mine who owns a 2004 Farrier F33RX folding trimaran, the 33′ Nelda Ray. This sailboat is a frequent competitor in regattas on the Great Lakes. The aluminum mast step was compressing the deck and causing laminate failure. I told my friend I’d figure out what went wrong and then fix it so it would never happen again. I’ll outline the process I used to make this successful repair. Continue reading →
Here’s how we recently repaired a rotted Chris-Craft transom. The boat* had rotted stringers, transom, cockpit sole, and other problems common in fiberglass boats. I’ll explain the process we used for replacing the transom to provide some direction on tackling similar projects. Continue reading →
The prep crew recently rescued and restored two Club 420 sailing dinghies using a combination of their own tenacity and West System® Epoxy. They achieved this through our youth sailing organization, More Kids On Sailboats (MKOS). At MKOS, we strive to let the kids lead, make mistakes, and learn how to do better the next time. The Club 420 project allowed them to do just that. Continue reading →
Upgrading our sailboat’s navigation instruments called for eliminating one thru-hull fitting and reducing the diameter of another by 1/8″. Takara, a 1974 Irwin 30 Competition, has a one-piece molded fiberglass and polyester hull with alternating layers of hand-laid mat and 24 oz. woven roving. Her original instrument set included a pair of 2 1/8″-diameter transducer thru-hulls in the bow. Upgrading to modern instrumentation standards required installing an NMEA 2000 network instrument that was 2″ diameter. Continue reading →
Knowing how or why your boat’s gelcoat cracks occurred in the first place is the key to a successful repair. For example, if hitting a seawall or dropping a champagne bottle on deck is what caused the cracks, after fixing them you will know how to prevent them in the future: Don’t drink the champagne causing you to hit the seawall and drop the bottle. Continue reading →
A very high percentage of boats in the U.S. are at least 30 years old. It doesn’t surprise me when a boat’s plywood components fail due to water intrusion. In my experience, the transom is the first area to rot out in most trailerable boats. That’s not to say the first thing to rot couldn’t be the cockpit floor, stringers, or motor mounts.

Many products, especially boats, are now being manufactured with a process called Vacuum Assisted Resin Transfer Molding (VARTM), also frequently referred to as infusion. The main topics of this article are: what infusion is, how to repair an infused part with vacuum bagging vs. infusion, and the results of our study comparing a vacuum-bagged repaired laminate and an infused repaired laminate.
