[CA] [CA11] EV-100 on a powerboat?

[aequitas1916]

Thanks for your help, Chuck. It's been a couple months and I'm finally getting back to this project.

I've confirmed with SeaStar, and the cylinder on my boat is indeed 7.2 cu. in.

Before I pull the trigger and potentially buy the wrong system again, could you tell me if the EV-150 will work for my application? 7.2 cu. in. steering cylinder, 34' length, 11,400 dry weight.

Based on the literature I can find, the steering cylinder I have is correct for this autopilot (EV-150), but I'm not sure what "small to medium sized" vessels means. I imagine the EV-200 would give me additional capability, but I'm really just looking for something to hold a course in relatively calm water. If the EV-150 will be adequate, I'd just as soon use that one and save some cash (you know how expensive boats can be).

Thanks again!
