A combination square is used to mark the two edges along the entire length of the corner before applying reinforcing fiber tape.

Reinforcing Fiber Tapes

By Captain James R. Watson

Above: A combination square is used to mark the two edges along the entire length of the corner before applying reinforcing fiber tape.

Composites are a blend of resin (in this case mixed epoxy) and reinforcing fiber. Folks often ask, “How strong are they?” It is difficult to answer this question due to many variables including resin type, fiber type, fiber orientation, and resin/fiber ratio. To give a value for a laminate, we reduce the variables. Values shown in this article were done with test samples using WEST SYSTEM 105 Epoxy Resin®/206 Slow Hardener® at room temperature (70°F). Reinforcing fibers are Episize™ materials. Continue reading →

The Glenn Curtiss Museum

By Mike Barker

Above: A 72′ wingspan reproduction of the 1914 Curtiss flying boat America was completed by the Curtiss Museum’s restoration shop crew in early September 2007.

Glenn Curtiss is recognized as the “Father of Naval Aviation.” He trained the first Navy pilots and built their first aircraft, the A-1 Triad Amphibian. It was “Curtiss Pushers” in 1910 and 1911, that demonstrated capability to take off and land on a ship, leading to the development of aircraft carriers. Continue reading →

Six10 Epoxy Adhesive

Introducing Six10 Thickened Epoxy Adhesive

Above: Introducing Six10 Thickened Epoxy Adhesive, a two-part adhesive in a convenient, self-metering cartridge for permanent, waterproof structural gap filling and gluing.

Six10® Adhesive gives you the strength and reliability of a two-part WEST SYSTEM epoxy with the convenience of a single-part product. Six10 is dispensed with a standard caulking gun. Non-sagging Six10 bonds tenaciously to wood, metals, fiberglass, and concrete. Continue reading →

Cover Photo: A small sampling of the Gougeon 12.3 canoe family. Robert Monroe’s cold-molded canoe (foreground) came from a half-mold that eventually resulted in the a 12.3 mold (object directly behind first canoe) which has been used since 1989 to produce dozens of offspring that reflect a wide raged of tastes and technology.

Above: The latest generation of employees and their Gougeon 12.3 canoes.Building a Gougeon 12.3 has become a rite of passage for new employees. 

The Gougeon 12.3 canoe represents several decades of experimentation by employees of Gougeon Brothers, Inc. Dozens have been built but no two are exactly alike. The evolution of the Gougeon 12.3 parallels our love of boating, passion for innovation and desire to build better boats—all of which contribute to the products we produce today.

Turning a Gougeon 12.3 into a Kayak

by Tom Pawlak — GBI Technical Advisor

Above: Tom’s wife Mary paddles aboard her Gougeon 12.3 kayak on the Rifle River Recreation area in Lupton, Michigan.

I recently modified the deck of my wife Mary’s fiberglass canoe (one of dozens built from the Gougeon 12.3 mold) to make it more seaworthy and to facilitate a spray skirt. More like a kayak. Previously, the decks covered only the ends of the boat, leaving the middle 40% wide open. I’m fairly pleased with how it turned out.

Six10 Epoxy Adhesive

Understanding Six10 Epoxy Adhesive Properties

By Jeff Wright — Vice President of Technical Services

WEST SYSTEM® Six10 is a two-part, pre-thickened epoxy adhesive formulated with properties that make it perfect for many adhesive applications. Compared to other ready-to-dispense adhesives, its particular physical properties make it ideal for stitch and glue boat construction, fiberglass laminate repair and general bonding. This new formulation has a good balance between the elongation and toughness of G/flex® and the strength and stiffness of our 105 Resin-based epoxies. You can use it with as many materials as possible including wood, metals and composites. The long working time with fast thru-cure and unique shear thinning are additional characteristics formulated into Six10 that contribute to its ease of use. Continue reading →

Practical Tips for Using Six10

by Captain James R. Watson

The WEST SYSTEM® Six10 epoxy cartridge is comprised of the cartridge body, removable nose plug, and a threaded retaining nut. A 600 static mixer is included with the cartridge. (It’s called a static mixer because it has no moving parts.) The cartridge fits into any standard caulk gun—manual, cordless, or pneumatic—and allows simultaneous dispensing and mixing of the two-part epoxy.

Kayak Lessons Learned

by Captain James R. Watson—GBI Technical Advisor

Above: Captain James R. Watson in his kayak. Note how the kayak rides at anchor from the bow.

Kayaks are versatile craft. I’m a lucky guy who has had decades of pleasure cruising, exploring, fishing, and simply relaxing on many different streams and lakes throughout Michigan and Canada in my stripper kayak. Comparing the investment dollar per pleasure derived, my kayak wins hands down over all the other watercraft I’ve owned. In her wake, I’ve been taught many lessons, albeit some the hard way. Here are a few I thought worth sharing. Continue reading →

The wet winter months in Oregon are perfect for garage projects like boat building and car restoration. They are less than “ideal,” however, if you want a perfect epoxy finish for your boat and your garage is unheated. Continue reading →

James Wharram Designs

by Captain James R. Watson—GBI Technical Advisor

For many decades Gougeon Brothers Inc. has kept in contact with multihull designer James Wharram. Wharram, of Cornwall, UK, has sailed and designed Polynesian-style catamarans for 50 years. Amateurs and professionals have built his boats and sailed them to all corners of the planet. The designs he creates with his engineer and artist partner Hanneke Boon have evolved over the years, but remain unmistakably, Wharram Catamarans.
