Re: Passport 41
It is possible to put a wind vane on a sugar scoop transom. Monitor makes one and it pivots out of the way when the boat is at anchor. This allows access to the sugar scoop for swimming and dinghy access. I have seen this on a Caliber 40 LRC.
It is possible to convert most sloops to a cutter rig with a solent stay. There is a good article on this modification in the current Sail Magazine. It is removable.
