So I've been commuting to work via SUP and river, been cold water paddling, have done overnighters and a lot of fitness lake-circumnavigation. The 12' 6" Boardworks Surf Raven has been a great board. I am needing to get past it's limitations. I can't seem to find a whole lot of info on longer touring boards. Does anyone have any info or can you share a few links for builders and sellers of longer touring boards? I'm looking for something in the 17 to 21' range that can hold a large volume. I'm 230, the dog is 60 and I'm thinking around 100 lbs of gear. I'm looking for a river barge, not a long missile. I don't need it to be the fastest barge board on the planet. I'm not out to race it, I'm out to cover 100+ miles on a deep, docile river or large lake or ocean while having all the gear I need for a week long excursion. Does anyone here have a SUP over 14'?
