There have been a few threads here on multihull
windvanes. If you are looking at a Lagoon
, you will not be using a windvane
While there are occasional reports of claims of success with a windvane
on other catamarans, take these with a large grain of salt
The problems are legion - ranging from the wind
being blocked or confused by the cabin
house to the boat acceleration causing the apparent wind
to change constantly.
Choose a good below deck autopilot
and make sure the installation
and mounting are bullet-proof.
