best flat water recommendation

[jbsmith]

What is the best board for lake sailing with consistent 15 to 20 knots wind speed? I weigh about 160 lbs and getting back into the sport after a 20 year lay-off. I anticipate using a 6.4 sail most of the time. I was a relatively experienced sailor living in Hood River and traveling to Maui regularly. My new board does not have to be a compromise for any other conditions.

Thanks!
