Now also in HD for iPad !yachtsman’s- or seaman’s knots are knots with special demands: - one must be able to fix them quickly - they have to hold save on tension - they must come easily undone after subjecting them to heavy load. There are of course plenty of knots, but to know just a view selected ones should be enough in the daily use of a beginning seaman. Those are exactly the knots being questioned at a yacht- or motor boat licence.
