I'm glad I'm not the only one with mechanical steering on a bigger boat. I was considering the wheel pilot- due to the cost, but dont think it will work cause of boat weight. (7000 dry- 278 BAHA)
Now I'm wanting, and waiting from a reply from Raymarine on using the X-10, P90R head hooked to a Linear 1 acuator, they asked to see a picture of rudder area. It mentions only about sailing vessels-BUT a overall 24000lb weight. Im thinking I maybe at 10,000lbs full (7000 dry)
Now what can be any different I ask? Im thinking it will be controlling the boat at high speeds which a sailboat can't achieve???? (Im guessing...) So then why not upgrade to the Linear 2 ram for the much larger sailing vessel? Im just tring to get away from the hydo upgrade. BOAT = Bring On Another Thousand, Right?
I will post what I find out from the Raymarine people, hoping it will work.

Come on Spring
