IIRC the article I saw (ages ago) the skipper / own sacrificed 2 berths out of 8 on the Cabin cruiser to accommodate the extra water and fuel capacity, the sail was a very basic design that looked like a viking longboat sail, just a big square sheet, it also had extra ventilation and metalwork installed to enable a wood burner to be fitted safely in the galley.
