Lightness and sturdiness
Flax fiber weighs half the weight of glass fiber, and compared to glass, the structural element of fiberglass, red cedar or okumé plywood – the two woods chosen to make a Nab – weigh a third and a half. As well as the necessary epoxy resin, used to isolate the wood from water and give monolithic compactness to the structure, weighs about one third less than polyester resin and about half less than vinylester resin. In short, in terms of weights, a wooden boat has an advantage over an industrial composite one.
Beyond the specific sturdiness features of the materials, the construction with structural interiors in charge of the dual function of furnishing and reinforcing, contributes to making the construction light and sturdy, with no need for bulkheads or reinforcements for the interior furnishings.
Considering the mechanical characteristics of the product, it goes without saying that, with the same crew, the sailing performance is comparable to that of high-quality composite hulls. Better than those obtainable with a mass-produced product.
