She went out again today on the 12,6 slight wind and side chop on Lake she went well never fell in but a couple of wobbles not bad for the third ever paddle on a SUP.
I went out also board tracks ok A little hard on the down wind as it's a little sucky but it is a inflatable the chop had got up a bit and stability was good I did however fall one after 5 km got side swiped by chop if the nose goes down between chop it does slap down hard vibrating through the board causing a element of instability but again it is a inflatable and the sport is not a race board.
I am a pure surfer but if I was to buy a flat water board I would not hesitate to look at the red boards myself .
Very good option for travel and or course you can leave it sitting on the beach /land all day you can't do this with glass or epoxy /carbon .
I have not had the chance to try her on the 11 sport but my guess is at over a foot shorter is maybe less stable but then for light riders maybe not .
The board is very easy to set up a fair bit of pumping yes 19 min as advertised but flat out pumping I was rather buggered afterwards

The side batterns are very easy to install
The bag is great , the only downfall of the package red offered in the sport and larger race sizes etc is no paddle.
Sure they are great and will do what I would say 70 percent of what a hard board will do but at the retail prices plus paddle there is a few hard board options about like the naish glide.
But you can't just pack a hard board in the boot of your car or in my opinion and the best is you can't leave a hard board in the sun while you bbq etc .
Over all yes I will but one for the wife and may very well get a second for myself off the used market.
