Balsa, Redwood, Cedar, and Spruce, to name a few. For most of our boards we use Spruce because, ounce for ounce, it is the strongest. It is also the most expensive. We take it one step further. Two pieces of wood that are laminated together are much stronger that a single piece of equal thickness.
All wood has grain and flaws.
By putting two separate pieces together, natural shear points are eliminated. In addition, the rocker of the shaped blank is more stable. Well, it costs even more money. To us, it's worth it to insure the durability of your investment. FCS One of the most notable changes in the surfboard industry in the last few years has been the overwhelming public acceptance of removable fins.
