Cover Photo: The SWIFT SOLO is a single-handed skiff built by Bram Dally. Stiff, durable hulls are crucial to skiff speed.

One of the little-known or understood characteristics of modern fiber-reinforced plastic composites is the loss of some initial stiffness capability after repeated cyclic loading. Loss of stiffness can be significant enough to cause a noticeable effect on performance, depending upon laminate makeup and degree of cyclic loading. Continue reading

Wooden Runabout

Mark Bronkalla of Waukesha, Wisconsin, built this Glen-L Riviera wooden runabout using WEST SYSTEM Epoxy. The Riviera is a 20′ double cockpit traditionally styled wooden runabout. It was built with cold molded construction techniques (epoxy and wood laminations). Top speed as measured by a GPS is 53 mph! For construction photos and building information, visit www.bronkalla.com.

Ed Van Kirk’s Guillemot Kayak

This Guillemot kayak (left) is the work of Ed Van Kirk of Constantine, Michigan. Ed built both of these kayaks of redwood and sugar pine, using Nick Shade’s book The Strip-Built Sea Kayak as a reference. The double-seater is a Guillemot kayak, 20′ long with a 30″ beam and weighs 73 lb. The single-seater is a Little Auk kayak, 10′ long with a 29″ beam and weighs 43 lb. Ed has also built a 14′ Wee Lassie Two. Continue reading

Laminated Canoe Construction Gives Lasting Value

John McKibbin sent pictures of his refinished 18′ laminated canoe. He built it back in 1976 using cold-molded, that is, laminated composite construction, with WEST SYSTEM® epoxy. Laminating a hull is similar to making your own plywood on a three-dimensional mold. While it may take more time and effort to make a laminated hull, the results are well worth it. Continue reading

Vintage Speedboat

Paul Schreiter of Appleton, Wisconsin found the plans for this vintage speedboat in an old library book. The design is a 1936 inboard racer but powered by a 120 hp Mercruiser. Paul says, “I will go as fast as you want.” Continue reading
