>One major difference between skegs and rudders that I have not seen >mentioned (in this recent discussion) is the tendency for rudders to >lift free in steep seas. We have one designer who places the rudder on the side (on Skerries), known as the Southern Viking rudder because he put it on the port and not on the steerboard side and they only appear on Southern Hemishpere kayaks. >...since it is a function of rudder >placement. This can be avoided by mounting the rudder under the hull, He has also modified a Skerry so that the rudder is mounted on the trailing edge of a cut back skeg, all retractable and retractable when striking the bottom. >The standard stern-mounted rudder does not pivot about its center, >but instead swings out to the side. Not necessarily, a number of us design and build them with a bit of balance, that is some of the blade is in front of the hinge line. Alex . .
