Construction Options - Fiberglass, Hybrid, Kelvar or Carbon?
Composite Construction Options
Hull and deck are vacuum infused construction with four layers of hi-tech fiberglass cloth and 45 degree unidirectional fabric, with Kevlar reinforcements in the keel.
Hull and deck are vacuum infused with several layers of fiberglass and a layer of Kevlar. This adds impact resistance but at an economic price. The weight will be 2-3 pounds less than the same boat in Fiberglass.
Hull and deck are hand-laid with two by two Kevlar cloth, with light fiberglass veil over the outermost layer for scratch resistance. The weight will be 4 - 5 pounds less than the same boat in Fiberglass. This is a stiff, lightweight hull ready for long touring adventures.
Hull and deck are hand-laid with with Carbon Fiber layer backed by Kevlar layers. Deck is Kevlar and carbon. The advantage of this lay up is primarily stiffness in the hull, the weight savings are not significant and will be 4 to 5 pounds lighter than the same boat in Fiberglass.
Many companies have very light carbon construction based on a foam core between layers. Seda designs, while fast, are not race boats, and are designed for touring or expedition use and constructed on that basis, and are not offered in ultra-light foam core layup. Note - not all models are available in Carbon construction.
