Compared to a conventional fixed 3 blade propeller the SLIPSTREAM 3 blade propeller will have around a knot less drag under sail and ½ to ¾ for the two blade comparison. Usually performance under power is improved over the small blade area sailing style fixed blade propeller. The feel of the rudder is also often noticeably improved, as the turbulence created by a fixed blade propeller can affect the laminar flow over the rudder blade, resulting in a vague feeling. Depending on the proximity of the propeller to the rudder this can be quite dramatic. Fitting a SLIPSTREAM propeller will allow the sailboat to comfortably sail a course closer to the wind.
