Use of Mister Vee Y&B Standard on a trimaran
I have a Marples 26 foot constant camber trimaran that to which I would like to fit wind vane steering gear, however, I note the comment in the guarantee information that the wind vane steering gear is not guaranteed for use with multihulls. I would be grateful if you could explain why as the Mr Vee Standard Y&B looks otherwise perfect for my boat.
All the best,
Windvane self steering can not cope with constant acceleration followed by slowing down. This means that it may not be possible to steer an ultra light displacement boat or multi hull.
A windvane self steering system uses the apparent wind direction to keep on course.
When the boat accelerates, the direction changes. The system will correct accordingly which will in the end make the boat slow down.
The course will again be corrected and the cycle starts again.
