yup, i have some plans, the original and my modifications. it's the drill and sew method, prety simple. it takes a bit less than 40 hrs, depending on your level of carpentry skills (just cut/drill/fit/fibreglass) and of the finish you like. 12.5-14', surfrider design.
there was a guy that was supposed to make one last winter, and i'll probabley make a new one with a new design this winter.
