Ralph Naranjo

Ralph Naranjo is a Practical Sailor contributing editor whose specialty is safety and seamanship. During his 10-year stint as the Vanderstar Chair at the U.S. Naval Academy, he augmented safety and seamanship training and played a key role in the development of the Navy’s 40-foot new sail training sloops. His sailing background includes a five-year family voyage around the world and the management of a full service boatyard. He and his wife Lenore have made two other lengthy cruises aboard Wind Shadow, a 41-foot sloop the Naranjos have owned for over three decades. During the past 15 years, he has moderated US Sailing Safety at Sea seminars across the country, and now is an adjunct lecturer at the Annapolis School of Seamanship. His newly developed courses on weather routing, seamanship, and celestial navigation are among the most popular in the school’s lineup. He is the author of Wind Shadow West, an inspiring account of the family’s five-year voyage, and The Art of Seamanship: Evolving Skills, Exploring Oceans, and Handling Wind, Waves, and Weather, a comprehensive textbook aimed at the advanced cruising sailor. For information about his virtual or in person seminars on a range of topics contact the editor at [email protected].

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.

Breaking Down Performance

When it comes to sailboats, performance is a relative term, especially when it comes to a crews concept of how the boat will be used. Racing sailors, cruisers, and daysailors each have very different perspectives on performance. For example, those facing a light-air, around-the-buoys race measure performance in terms of how well their speed through the water holds up against the decrease in true-wind speed. Cruisers, on the other hand, especially those crossing oceans, often define it as a measure of versatility under sail, not just how a boat copes with near calms or gales, but how it performs in everything in between.
