An asymmetrical or cruising
spinnaker is essentially a light-air sail, so think about the generally prevailing winds you experience as part of your consideration regarding purchasing such a sail.
I have a 350 and sail the Chesapeake Bay out of Annapolis. I have a 3/4-ounce Quantum V3 asymmetrical
spinnaker and there is ample opportunity for flying it, especially during the summer.
