I've sailed Nockamixon, and Wallenpaupack, and I too would have a different suggestion for a first boat. I'd suggest a keelboat, small is fine. They are less likely to flip or fill the cockpit with water.
TakeFive is 100% on Nockamixon, Haycock mountain screws the winds terrible there, but it is a pretty easy lake to learn on, and the sailors there are pretty great.
Hey SCHNOOL, welcome back! I hadn't realized that you moved to Virginia. I guess at your new location you no longer have to sail uphill?
My recommendation of a Sunfish (or similar) was based on several advantages:
Easy to find
Cheap to buy
Big user base with lots of support
Easy to transport - by trailer (preferably) or on car top if needed
Easy to rig (lateen rig)
Easy to sell
Since OP admits he doesn't know anything, and isn't even sure he'll want to stick with it, I figured it's the safest bet in lieu of lessons.
I have no objections to him going larger, but for a guy who wants to learn on his own (due to potential unavailability of lessons this year), it seemed like the least expensive and least risky way to get on the water, with an easy out if he doesn't like it.
For those who are suggesting larger boats or keel boats, let's see some suggestions of actual boats for him to buy. But let's not convince him to get a cheap project boat - the guy wants to sail, not spend a couple years refitting.
