From lots of testing different volumes, shapes, and sizes, this board rocks!!! For us it is the perfect volume, it is light, it is strong, it isn’t too large or bulky, it doesn’t sink too much when tacking, and it is easy to water start. The regular size also doubles as a surf foilboard if you don’t weight too much.
