Repairing Bow Damage on a Lightning Sailboat

By Terry Monville – GBI Technical Advisor

Getting started on any project is half the battle. This could not be truer when it comes to an unexpected fiberglass repair. Every crashed boat is different; making every repair a bit different. Some repairs are straightforward, textbook repairs. The damage occurs on a flat area of the hull that is a solid fiberglass laminate. A little grinding, a little fiberglass and you’re done. What happens when the repair is not so simple though?

Replacing the Wet Core in Another Spade’s Rudder

By Don Gutzmer – GBI Technical Advisor

What happens when the core of a water-damaged rudder can’t be saved? Completely replacing the core of a rudder may need to happen for a variety of reasons. There may be an inability to dry the core and still maintain the structural integrity, or the repair may need to be completed in less time than just letting it dry. The rudder from Another Spade, a C&C 32 sailboat, had a wet foam core that is beyond saving. Here are the steps I used to restore this rudder.

Patching up Shenanigans with Fiberglass

By Ray McCarthy

A friend gave me his well-used 1980 Sunfish sailboat, Stinkin’ Tuna. He and his brother had learned how to turn the boat (tacking) by ricocheting off rocks on Long Island Sound. Over the years they had kept the wreckage floatable with the application of non-hydrodynamic fiberglass patches. Though they made the boat functional, they hindered the boat’s performance. Time to get to work.

Calculating Laminate Thickness

By Rachael Geerts – GBI Composite Materials Engineer

Have you ever wondered how laminate thickness can be determined without breaking out the epoxy and reinforcement fabric? The answer is simple—use math. While some of you may have just lost interest because you think math is too difficult, I can assure you that this math requires nothing more than some basic multiplication, addition, and division. Let’s get to it.

Preparing to Fair

By Greg Bull – GBI Technical Advisor

Those new to the process of fairing a boat’s hull or deck are quick to mix up a batch of fairing compound, WEST SYSTEM® Epoxy with a low-density filler, and apply it to the surface, so they can start sanding right away. My experience in boat repair and construction has taught me the importance of making a fairing plan and selecting the correct materials before any epoxy is mixed.

Proper Fastener Bonding

By Terry Monville – GBI Technical Advisor

Typically, when a fastener fails on a boat, it pulls out of the wood or fiberglass that it was screwed into. There are many causes for this failure: shock loading, fatigued from being pulled on one too many times, or moisture softening the wood. Let’s take a look at how using WEST SYSTEM® Epoxy can improve the holding power of a fastener in wood to give you fewer troubles on the water.

Repairing My Boat’s Plastic Console

By Craig McCune

After 20-plus years of vibration and pounding on the water, the molded plastic console on my 2001 Lund® boat was riddled with stress cracks and broken pieces. All of the fastener-mounting points were stripped out or broken. As often happens with older boat components, replacement parts were no longer available. I’d have to repair the console myself.
