Due to the rather small sail area (just 19 sqm) and the design of the sail (the shape only forms under wind pressure) Proasis has always been a bit slow in light wind from behind. We thought about getting an additional downwind sail for a while an now finally got hands on a good second hand asymmetric spinnacker. Finding one that fits our short mast was not easy but apparently we can conveniently use the sail of a Hobie 15. It’s just 6.5 sqm but gives a notable boost of thrust. It can be hoisted either on the leeward bow if the wind is blowing more from the side or to the windward bow if the wind is dead from the aft.
