Balsa Core Alternatives

By Greg Bull—GBI Technical Advisor

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

BO-PEEP II underway.

BO-PEEP II 75-Year Refit

By Ronald Lane

The motor yacht Bo-Peep II is a 55′ bridge deck cruiser designed by Hacker-Fermann Naval Architects Co. of Detroit, Michigan. In 2001, BO-PEEP underwent a major refit with extensive use of WEST SYSTEM® Epoxy. Two decades later, the benefits of this approach are apparent in hull longevity and strength; dry bottom blanks, frames, and keel; a dry bilge; dry bronze thru-hull fittings, hardware fasteners staying put; shorter shipyard haul-outs; and the propeller shaft remaining properly aligned. We no longer have rotted planks or loosened fasteners to replace, seams to caulk, or corrosions headaches. Continue reading

BO-PEEP II's tender

Restoring BO-PEEP II’s Tender

No more replacing rotten planks, no more replacing fasteners, no more caulking the seams, and no more corrosion headaches.

By Ron Lane

The original wooden tender for the BO-PEEP II was also built by Defoe Boat and Motor Works of Bay City, Michigan in 1926. This tender needed a few repairs. Satisfied with the performance of the repairs done on BO PEEP II with WEST SYSTEM® Epoxy back 2001, I decided to use WEST SYSTEM in restoring the original tender in 2014. Continue reading

This Cal 33 underwent a wet rudder repair

Wet Rudder Repair

By Terry Monville—GBI Technical Advisor

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

Cover photo: The Farrier folding trimaran Nelda Ray under sail following Don Gutzmer’s aluminum mast step repair.

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

Spraying epoxy; please don't.

Spraying Epoxy

Please Don’t

By Rachael Geerts—GBI Composite Materials Engineer

Every year we get questions regarding how to spray WEST SYSTEM® Epoxy. Some people want to know how to thin epoxy so it comes out of a spray gun better while others want to know what Personal Protective Equipment (PPE) is required for spraying epoxy safely. We give them all the same answer: Don’t do it! In short, epoxy is extremely hazardous when sprayed. Continue reading
