I am having to replace my rudders due to beaching damage.
I would like to make them from composite materials to keep them light and also be able to lift them as my boat is on a drying mooring. So my question is has anyone designed a system they are willing to share, so I don't have to reinvent the wheel. Any ideas or comments please.
Boatsmith has fitted lifting rudders in the T8m. You can see it in
I don't like the gap between the rudder and hull (it can catch underwater ropes), but I see that BS has changed the design, see
I'm sorry but my english is not very good and I don't undestand well your idea. You can make a rudder to be of a pivoting type, a lifting type or a combination of both. I think you want the last option, which is the most complicated.
Ian Farrier has this type of rudders in his trimarans, but I think is a little high tech (you can see it in http://www.f-boat.com/f-33/f-33newfeatures.html); there are other types in Crhis White's book "The cruising multihull".
