Windtunnel tests were done in the windtunnel of the Wolfson Unit in Southampton. A scale model of the Ecoliner was placed in the 4.6 m wide by 3.7 m high tunnel. Various sail configurations were tested including 3- and 4- mast configurations carrying 900 m2 and 1200 m2 sail area. Also the effect of reefing and the effect of deck cargo were investigated.
It can be concluded that a 4 mast rig does not provide a convincing aerodynamic advantage over a 3 mast rig and therefore 3 masts is the preferred option. The amount of sail area depends […]
Ecoliner and the SAIL project are today on the front page of La Voix du Nord, a major (>500.000, all editions) regional French daily. This is thanks to their short stay in Lille for the last Regional Meeting.
