Pblais: I'm sorry for making some confusion over the term "tiller." I can see a big misunderstanding here, due to my lack of clarity. The tiller in this case for an electric/hydraulic ram would be about 11 inches long, attached to my rudder
stock below the swim deck, in fact, attached just below my 20 inch Edson
quadrant. (Aft facing, under the swim platform/sugar scoop transom, but still in a nice dry inside space.)
would explain it better maybe.
My steer-by-wire system goes to a center-cockpit steering
wheel of large diameter. I ran this 48' steel
boat with a Sailomat
windvane for about 30K miles from SC to Guam
and back over a number of years. The Sailomat vane also ran it's lines to a short aft-facing tiller, one that was a few inches above the swim platform. The new tiller for the AP will be a few inches below the swim platform, but still "in the hull" nice and dry. (My swim platform is about 8' wide by 4' fore and aft. Plenty of empty, dry interior
is below it.)
Anyway, the tiller for the Simrad or WilHamm AP ram will be an aft-facing 11 or 12 inch tiller just below the 20" quadrant on my rudder shaft. I have plenty of room for a hydraulic ram extending 90 degrees from the end of the short, aft-facing tiller, over to the side of the area below the swim platform. I just want information about the best ram to do the job, that will fit in the space.
