Hello Rudolf,Why are you replacing original rudder system ?What did you like and dislike abought the original rudders and what will you gain with new rudders mounted on beam ? Are you going to reuse the old rudder blade and case or build new ones for beam mounted system and leave old system in place as a backup till you have tested new system ?You have a fantastic boat and your work with the blind I can relate to as my father was blind (visually handicapped and gradually went blind). He had a small sailing kayak,a folbot or similar back in the 50's which he sailed on the Chesapeake bay and taught me how to sail.Happy sailing,George Kuck,Chestertown, MDPS; Do you ever plan on sailing to the Chesapeake bay or any long distance cruising ?.--- On Thu, 11/6/08, Rudolf vd Berg <rpvdb@freeler.nl> wrote:From: Rudolf vd Berg <rpvdb@freeler.nl>

I wouldn't have a hinged rudder as you describe, or someone has to prove it can be done first.Too many parts and things to go wrong in my opinion. Full Size HP rudders have to be very strong, one piece seems to be best.The huge loads on the rudders calculated for BD have made me think of other solutions, but if two full size rudders work well that may be the simplest solution when shunting and number of parts needing attention for best performance.Reducing rudder area would make them less vulnerable but has to be compensated.BD will have full size beam mounted rudders. Plan is to get it sailing next spring.Rudolf.
