I hope you give it a try. I'm a passionate kayaker too. Stand up paddle board is a great compliment to kayaking. We have 4 kayaks and 2 stand up paddle boards. I look forward to reading more about your opinion on giving SUP a try. http://baffinpaddler.blogspot.ca/2013/08/sup-junkies-unite.html
Nothing is imminent for us on the SUP front at the moment, but we will it a try sometime this year. Have no fear, we'll keep our readers up to date on any SUP exploits.
