I have the very same board. Fun piece to have. I haven't SUPed much, but fun things to do are light-wind sailing, longboard freestyle, social sailing in the shallows, and teaching.
It actually planes surprisingly well in stronger winds too, though of course I'd rather take out shorter boards then. Gybes beautiful, basically all by itself, though not a great upwind pointer.
Here are a couple of possibilities with same board, that is, tacking the railride to a front-to-back, and gybing from inside the boom, facing the wind. Fun board really.
