Wingsurfing is a super fun way to get out into the water and wind! These boards are all good places to start and will work well in light wind locations. The bigger the board, the easier it will be to get to your feet, so go for the larger sizes when you're just getting started. Longer lengths will glide and track better, wider widths will be more stable.
Some of the windsurf boards have a center fin or a daggerboard- these will track much better and even allow you to sail upwind! Most of the SUPs only have tail fins- these will drift a bit more and might not track as well, especially upwind.
