Stuck Like Glue: Epoxy Resin Mechanical Performance Testing
Just about every sailboat owner has at some point mixed up a batch of epoxy to fill a hole, glue parts back together, or tackle an extensive project. Practical Sailor testers evaluated four marine epoxy resins based on their mechanical properties (strength, adhesion, hardness, and flexibility) and key handling attributes such as wet-out, sag, curing, and overall handling. We tested West 105 Epoxy Resin, MAS Flag Resin, Raka UV-inhibited epoxy, and Interlux’s Epiglass HT-9000.
Wood Rot Prevention: What Eight Years of Extreme Exposure Testing Taught Us
Wood is strong, stiff per unit weight, easy to work with, attractive, and economical. And it rots. A few special types of wood, such as teak, are highly resistant to rot, but these woods are generally heavy and almost always expensive. Pressure treated lumber is an option, but it’s ugly, warps, does not take coatings well, and is not always very rot resistant. Western red cedar, on the other hand, has long been used in canoes, and cedar fence posts have a deserved reputation for durability.
We started our rot resistance testing eight years ago in 2015, and we finally cleaned out our accelerated rot test box in July 2023. Results ranged from abysmal (untreated samples of fir have nearly disappeared) to astounding (our teak samples are still just like new). Let’s see what we learned.
