Rob's Sol rudders are the best design so far for strength simplicity and ease of retracting.   Doug  --- On Thu, 27/5/10, gardner.pomper <gardner@networknow.org> wrote: From: gardner.pomper <gardner@networknow.org> Subject: [harryproa] new rudder concept To: harryproa@yahoogroups.com.au Date: Thursday, 27 May, 2010, 12:00   Hi, I just posted Rudder.pdf under Gardner's Layouts in the Files section. I keep wanting to use asymmetric rudders, so here is another drawing about how it might work. The rudder blade has a pivot pin near the top (maybe 6") that the rudder can tilt forward and back around, due to the water pressure of the moving boat. There are sacrificial break-away pins fore and aft that keep it from tilting too far. This is all attached to a rudder mount that has a square rudder shaft attached to the lw side. This square rudder shaft can be raised and lowered vertically. It goes through a stub steering arm that gives teh steering cables some leverage to point the rudder +/- 30 degrees (or whatever is reasonable). Then the whole bit is attached to teh lw hull through a brace mechanism similar to what Rob is doing on Solitarry, except that it is fixed in position, so it can be made as strong as required. So, comments? - Gardner
