Here's an interesting concept from YOLO - an 18' x 30" multi person board. This would allow DJ to take total newbies out on downwinders and really blow their minds.
Starboard is marketing the 16' x 33" Inflatable Astro as a tandem board. Is this the future of SUP cruising?
I think there was one group that did the distance race at BOP last year on a 4-man SUP... wonder if anyone has some pics?
Found this info from Infinity SUP - looks like a lot of fun on flat water!http://www.infinitysurf.com/sup/tandem-sup/
