The Wooden boat design competition has two HP designs, Nols' Wantoo and Rob's Expeditionarry. To learn more about HP's I tried to read the plans and understand in what way they are comparable and in what way they are different and in what way that could be tied in to the difference in their mission. Expeditionarry is a speed machine and thus more true to the mission intended by this competition; I suspect Wantoo has been more influenced by the mission of BD, namely, a safe cruiser. Both have quite a number of fun "inventions". I first was quite surprised about how few of these could be transplanted to the other design. In hindsight I should not have been. There are probably quite a number of features which I do not even know that I do not understand yet. Let me start with with those that I do know:
The position of the masts are more at the extremities of the lee hull on the Wantoo and that does not appear to be due to the length of the boom/wishbone. This would make the boat more sensitive to the difference in lift. Both designs choose to fix the position of the rudders to those of the masts. As the Wantoo is about twice as heavy and has a lee hull about 20% shorter would the position of the masts be a response to its slower speed?
