310 performance
I have a 1999 H310 which for, aside of some very small changes, is the same boat as the 320.1.) Offwind; I have a asym spinnaker that I use in in light air under 10kts. I have to sail a little off from a ture down wind run. The boat flys !!!When I get lazy and or short handed, I run at wing on wing. It works well and in 10kts. of wind, I see 4-5+ kts. in speed.2.)Light air performance, See above; Spinnaker up to 10kts. running or reaching. Or, let it all out. With 545 sq. ft. of sail area, you will move at a good speed.As far as higher winds, 1st. reef in at 15kts. and the boat flys!!!!! I have seen up to 8.4 kts in speed on both GPS's and my knot meter on a broad reach, which is the boats best point of sail.There is a H310 owner on Lake Peppen which should be in your area, you can find him through this site. Just do a search for 310 owners. He should be able to answer a lot of your questions.I sail on Lake Winnebago, I assume you will sail Lake Peppen or Lake Superior. You'll love the boat.If you can swing it, get the spinnaker package and the autopilot.Let me know if I can help with any questions.Goog luck.Steve,s/v The Odyssey (H310)
