Something to think about before going to a smaller board... if you are (just) holding your sailing line now, you will have to work harder on a smaller
board. The reduced plaining surface requires more effort to control your field position and stay on top in less than perfect wind conditions.
If you're ready for the challenge, there are many good boards out there. The Vari Pro from Cabrinha has a wide outline that will help you in
variable wind, 3D pads, 6 fins for a strong bite and a trick handle. They're a bit costly, but a board that would serve you a long time.
