I'm quite a bit puzzled that the windsurfing market does not seem to accept a 15 footer Serenity but its no problem for the SUP market to get on with a 14, 15 or even 16 footer long board.
Why making a shorter Serenity ? Something like that : http://www.star-board-sup.com/2013/p...-0-x30-touring
? Does 30 cm makes a huge difference to you for say a shorter Serenity mk III ? Please explain...
