The Dotan daggerboard is made of directed glass material reinforced with polyester. Molded under a multi-ton load combined with thermal stress, the Dotan daggerboard's manufacturing process is unparalleled anywhere in the world in terms of efficiency.
The Dotan daggerboard's manufacturing process is more efficient than vacuum technologies many times over.
The Dotan daggerboard also differs from other daggerboard in that it is structured with reinforcing longerons and ribs inside the daggerboard. This atypical structure gives the daggerboard extraordinary strength and eliminates vibration.
The profile of daggerboard is designed on the basis of the NACA 0009 hydrodynamic profile (National Advisory Committee for Aeronautics).
