why not go for one sail for reaching and running : The parasailor.
It combines 2 sails in one ( a gennaker
and a spinnaker
It can be used between 70 and 180 degrees to the wind
More and more bluewater cruisers use this sail.
According to Bobby Shenk, Germany's most famous sailor ( who uses this sail on his Privilege
465 ) it's a must have on any yacht.
During a 15 day trip from Cape Verde
to Trinidad he kept it flying non stop ( day and night ) for 14 days.
The opening in the sail ensures that air flows over the wing and it functions as a pressure-relief valve.
of the wing relieves the pressure on the bow considerably and reduces rolling, yawing and pitching. Despite higher speeds, this allows much more balanced steering
and greater sailing comfort.
