I have acquired what I would describe as a 'dagger plate' > off an old catamaran for $10 or so, hardwood, but nicely foil shaped and > about 400mm long and say 20mm wide at hull depth, and tapering off. Something tells me, it is either 200 mm wide, or 20 mm thick :-). I like this path. Steve Isaak used it for his trimaran (Sunfish dingy rudder blade): http://www.watertribe.org/Magazine/October2000/Oct00IsaacRudderPage2.asp , and here is a home-made foil blade used for sailing Folbot GII, the boat is very similar to Klepper II and with the same sails as Steve's trimaran: http://206.40.48.186/uploads/RUDDERPROTOTYPE%20001(1).JPG - not sure if link will work, may be you'll have to log on to Folbot forum -> Yachtclub -> article "sailboys hand rudder controls". *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
