![]() ![]() ![]() Consider, though, that the typical summertime coastal cruiser will rarely encounter the wind and seas that an ocean going yacht will meet. ![]() It is based on the fact that the faster the motion the more upsetting it is to the average person. It provides a reasonable comparison between yachts of similar size and type. This is a ratio created by Ted Brewer as a measure of motion comfort. The lower a boat’s Displacement/Length (LWL) ratio, the less power it takes to drive the boat to its nominal hull speed. A sail area/displacement ratio below 16 would be considered under powered ġ6 to 20 would indicate reasonably good performance Ībove 20 suggests relatively high performance.Ī Ballast/Displacement ratio of 40 or more translates into a stiffer, more powerful boat that will be better able to stand up to the wind.īal./Disp = ballast (lbs)/ displacement (lbs)*100 ![]()
