Many rudders and keels pop right out of the mold with a sub-optimal shape. Add in years of sanding and repair work by well meaning yards and crewmembers and even your beautiful smooth rudder can easily be out of shape and robbing you of speed. COSS provides keel and rudder templating to make sure you are getting the best out of your boat! Based on your vessel and its foils, we will template your rudder to the appropriate hydrodynamic NACA foil shape. Followed up by our paint and burnishing services and you will be ready for speed.
