Here is some beautiful Sitka Spruce Fine Grain timbers that will be used to make Masts and Spars for Wooden Boats. These pieces are 9″ thick and 12″ and wider widths and up to 27′ long. Sitka Spruce has an excellent stiffness-to-weight ratio, and is available in large, straight-grained pieces, lending this timber to a wide range of commercial uses. Uses include aircraft components, musical instrument soundboards (guitars and pianos), boat building (mast and spars), wind turbine blades and any application where a wood material with a good strength-to-weight ratio is required. The 3rd picture shows a technique for making wooden masts, called “bird’s mouth” construction. This is supposedly stronger than a solid piece of timber. Interesting!
