I don't think some on this forum have realised how big SUP is in many places. There would be 50 times more SUPs than kitesurfers and windsurfers combined on the East Coast of Australia. Anyone can SUP so people buy them so the whole family can use the board. There are even SUPs for hire here that can carry half a dozen or more people standing at the same time
Super SUPs! In our small coastal area we even have a SUP warehouse. Man they are everywhere.
Moving a SUP requires a paddle and paddling can be slow and tedious especially if there's wind. This is where the Wing-Surfer comes in, don't paddle, let the wind do the work. I think the nature of the Wing-Surfer appeals to SUP owners as an easier way to move the board, and when the concept is relatively new, it has a cool factor as well. I think a lot of the Wing-Surfers will ultimately be sold to people who will never use them for foiling, just moving the SUP and maybe catching some small waves. Setting up a Wing-Surfer is also easy, not much pumping, no lines, safe and portable.
Now this may not sound exciting to members of this forum but I don't think we are where the money is. Ordinary folk with a SUP are far more numerous and they'll think the concept is fantastic and buy Wing-Surfers as fast as they can be made until the market is saturated. There will no doubt be a lot of marketing buzz around these "revolutionary" wind wings and there will be mass produced wind wings being sold in department/sports/outdoor stores and online for much less than they are currently.
So you may not want one, but your girlfriend/partner might...
