S39 ARROW Rowing Oar
Small diameter shaft
S39 shafts are made using high modulus carbon, recently used in the America’s Cup boats. They use multiple layers of thin carbon plies at various angles to achieve a balance of strength, stiffness, torsional stiffness and are very light weight.
The S39 has less aerodynamic drag than normal shafts and because they weigh less has less rotational inertia.
