The Hobie 14 is a simple boat that's pretty easy to learn. At first you may get frustrated when trying to tack. There's a knack to it, especially on a boardless, jibless boat like the H14, but you'll get it.

From the sounds of it, you've got a nice little lake to learn to sail on. Warm water, light to moderate winds, small size. You'll be just fine.

Your idea about hanging out where other sailors frequent the lake is a good one. You'll find that folks are eager to help for the most part (same as on this forum).
