Welcome to the forum Dewey, Your not to big but it depends on what you want to do, my lad and I have sailed on his 11 ft Arafura Cadet going along fine total weight of 145kg or 320lbs and the F12 has a greater buoyancy. You can sail in light wind or if you have plenty of wind where you sail you'll have great fun on the F12, you can pull the main sheet hard on the high aspect sail and have control in 30knots
