Wendy,

OCRA has a fleet of M4.3, I think. Their first regatta is at Alum Creek near Columbus (a little closer than Put-in-Bay) the weekend of May 6th and 7th. I am sure you could get some tips from that group, as they have been sailing the M4.3s for years. OCRA is a great group and they would welcome you with open arms! Just a thought.
