The 8 m range is interesting for many boat owners. So here a variation of the theme. The boat is actual 8,25m long. There is some accommodation in the hulls. The biplane rig is now the standard rig. The plans show also how to build them. The sails are furled by mast rotation.
ECO 7.5 Here the next ECO 7.5 which is under construction in India. The boat is 7.5 m long without the rudders. This one is build in the original wood/glass/epoxy system. An other one also almost ready is built in Thailand in a sandwich system.
