I recently completed a Monitor windvane selfsteering project on my MkV and thought I'd post this in case anyone else was considering this. Scanmar now has custom installation plans for C&C 27 MkV.

(1)who is the manufacturer of your boarding ladder?
(2)your windvane looks pretty complicated compared to the raytheon autohelm that my "magique" has that drives the tiller. I guess the windvane has a lower carbon footprint than a battery-operated autohelm?copasetic
Hi. Might I ask how much this unit cost, and if it would work with a tiller version Mk V? How long does it take to engage and disengage it under sail?
Thanks Barry Oasis, 1987 Mk V

(1) the gadget came with the boat when I acquired it last year-so I can't help with the cost. It is a Raytheon ST1000 Plus- manual has a 1998 date. It does not interface with a gps. The model ST2000 Plus does interface-I have used this on another boat.
(2) my markV is a tiller boat. The disengagement is extra-easy. The arm of the autotiller has a small hole which fits over a small pin on the tiller. Simply lift the arm and you are back to human control. When you want to go back to auto-simply reinsert the pin into the hole in the arm and restart "otto".
I enjoy it when single-handing as I can mess around with sail trim and the steering is better than I can do. It is probably not as good as a human when beating in a breeze because it doesn't know about puffs or swells etc, so its decision-making skill is a little below mine-but not way below
I think the real trick is doing a proper installation=which had been completed by a previous owner.copasetic
Sorry for the confusion, I was actually wanting to ask these questions about the wind vane. Oasis is also has tiller steering, and I was wanting to learn more about wind vanes.

Barry,
Yes, windvane self steering works very well with tiller steered boats. The Monitor unit has a tiller adapater kit as well as the wheel adapter kit. Check the Scanmar website for the price list. It isn't cheap (glad I committed to it before the October crash), but I figure it is a life time investment - I can take it with me to any other boat I eventually might own with minor modifications to the mounting frame.

Copasetic,
I don't know who made the ladder; it was on it when I bought the boat three seasons ago. There are a lot of resources on the web about the relative pros and cons of windvane vs electronic autopilot self steering and I won't go into it here. Autopilots work off electronic inputs mainly magnetic compas and are better for motoring to a fixed point. Windvanes work off the aparent wind and are better for sailing which is what I mostly want to do.
