What is the difference between abrasion and impact? What materials hold up best against each of them? These questions often come up when talking about skid plates. Skid plates are a protective layer, typically on canoes and kayaks, that reinforces the areas of the hull most likely to suffer damage from abrasion and impact. Continue reading →
Looking for an entry-level composite project? One that needs a minimum amount of materials and construction space, costs less than a boat, but still lets you travel on water? If you live in snow country, why not build a pair of composite snowshoes?
These snowshoes are made from a rigid foam core between two layers of carbon-fiber cloth, edged with 1″ Kevlar tape. A carbon-fiber wrapped wood spar runs across each snowshoe under the ball of your foot. This provides a solid mounting point for a couple of stainless steel eye-bolts to attach a simple toe-and-heel strap for a binding. Fiberglass tape reinforces the top and bottom edges, and the upper surface of the snowshoes where your winter boots contact them.
Braided Kevlar®, or composites with Kevlar and carbon braid, are used for joints and many components of my sailing canoes. These include the hull/deck joint, cockpit coaming and spray deck rims, the leeboard bracket and retaining pin, the attachment of the mast step to the hull, the gunter’s yard heel fitting, and the Continue reading →
