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.

Making Appropriate Structural Reinforcements to Your Boat

By Jeff Wright – GBI Vice President of Technical Services

Before starting on your next fiberglass repair or boat modification, let’s look at some projects that would most-likely require you to make appropriate structural reinforcements to your boat. After all – boats are complicated structures. Sailboats endure multiple loads from the rigging as the shrouds are pulled in tension and the mast is compressed into the hull. Inboard-powered boats must transfer the thrust from the engine mounts into the stringers while outboard and sterndrive boats place substantial loads on the transom. Even the steering wheel at a stand-up helm can undergo high loads when the boat moves fast through large waves — the security of which many go-fast boaters may take for granted. Let’s dive in.

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.
