We are in a light to med wind area on mobile bay.Our PHRF class is J 30s, Pearson Flyers Olson 911's Santa Cruse 27 and others. We all rate 3 seconds of each other with the express @141 and others @138.Would a mast head spinnaker work in these wind conditions with a 6 second hit and would it pay to cut the pole back and only take a 6second hit from our base of 144. istead of 9seconds total. thanks P S the boat goes back in the water in 2 weeks and I need to have all my bases covered as I brag alot. thus I'm keeping the old name on the boat.
