I recently developed new efficient daggerboard and rudder for my Sunfish. See aerosouth.net A friend in Florida has asked me to do the same for his Laser. I have the overall dimensions but need yet details on the foils used for both, as these are the baseline for my design. I used the same approach on the Sunfish and the results were quite good. I do not own a Laser (yet) but was hoping someone might know what foil is used on the current board and rudder. The drawing in the rules show foils that are much thicker than the actual shape, which should be around 10% thick based on the constant chord. Thanks in advance.
