Plenty of installation examples listed here:

Suggest your review a bunch of these to try to see why yours isn't working...

I agree with Faster. The Cape Horn is pretty bulletproof. You should be able to get it to work. Where are you?

Re: Need advice for autopilot

Below deck auto pilot is best, but expensive and a complicated and long install. If you are looking for a quick solution, and a very durable one at that look at the CPT autopilot. CPT Autopilot Inc. They have a reputation of working on very large boats simple but can't be connected to a plotter. (but then again neither can the wind vane!) You are about the limit for the Ramarine one. I believe Mainsail has one on his, and says it works well (may be putting words in his mouth but I think that is what he said). They have a new one out and it states 16,000 pound limit, so you are over it but if you keep the sails well trimed and the helm balanced it seems it should work. I don't see auto pilot wind vane being a one or the other thing anyway. There are times such as motoring that a vane will not work well. And an autopilot will put you right into the the wind while putting up and taking down sails, not a vane's strong point.

Re: Need advice for autopilot

I have a newish CPT autopilot. It is rugged for sure. Loaded, our boat is close to 40,000 lbs. We only use it when there is no wind and it seems up to the task. The control/sensing unit seems very sensitive to magnetic influences. The CPT uses a magnetic compass and we could not install it where the control unit for the old Raytheon unit had been - just too much magnetic stuff there - CPT mentioned a problem with throttle and gear cables. Once we moved the control unit it was fine, but you do need to fiddle.

You should be able to get the Cap Horn to work, especially with the help of Yves. We have a Monitor and our experience would suggest two areas of difficulty. One is that the boat absolutely must be balanced. For us that has meant eliminating weather helm by reducing the size of the main. We have a roller furling main and just roll in enough sail until we are balanced. Try over-reefing. If you don't need to reef, put in one. If you need one reef, put in two. Also do not have the main sheet overtightened. We can steer our boat when the Monitor is on by moving the mainsheet in and out - even a few inches will change the course. Vanes are very sensitive devices, but once you get if figured out it becomes very easy. i don't know how the Cap Horn works from the vane rudder to the wheel, but it really matters to have minimum friction. We ended up experimenting with various blocks, but now use two Harken and two Ronstan bearing blocks. There is a fair bit of tension on them and they are constantly moving. If the blocks do not turn effortlessly it becomes much harder to steer the boat.

Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.

Re: Need advice for autopilot

I am near yarmouth nova scotia making my way south along the coast.

The problem we have with the CH is the ship, really there is no room to work on it

we are 3 guys onboard only one can fit and we are not big or fat, you need to be really

small to fit in.

Hey,

What do you want the autopilot to do? Should it be able to drive the boat straight ahead in calm conditions, follow a route on your chart plotter, steer the boat downwind in large following seas, keep the going going when motoring, steer upwind?

Steering downwind with large following seas is going to be real tough. Having something to help you steer in light wind is easy....

Re: Need advice for autopilot

I would like some advice on the same topic.
I don't have an auto pilot. my budget does not extend to wind vanes and probably not to a under deck pilot.

My Boats a C&C 35 111. Is the raymarine wheel pilot. good enough? for coastal cruising. Steer a straight while I make tea?
Reasonably reliable? Hard on battery?
Easy to fit?

Re: Need advice for autopilot

We're using a RM S-1... works fine for calm motoring, straight line while hoisting/dousing sail, reasonable on smooth reaches not so well on quartering seas or lots of/variable winds.

Prefer to steer anyway while sailing so it serves us well for what we need/want.
