Yep, and if they wanted to be really environmentally friendly it would probably have been better to just buy a second-hand boat in the first place. I wonder if the mast can be left in the centre of the track, and if it's being moved by an electric winch?
The mast was originally moved using an electric winch if I remember rightly, but the way I read the ad it is now fixes. Boat was designed for trading, so not intended to be frequently manoeuvred. The rig now looks very similar to Rus Brown's proa Jzerro (realy interesting bloke/boat/voyages if you want to look into it..)
tacking (shunting)
and sailing confortably in the high teens...
Jezerro sailed from Washington to Australia if anyone doubts the concept...
