once up to a real lick it seems to be a little off. I need to play about with the rear wing.
I've heard the same thing from someone else that got one. He said roll stability is a problem
I think I got to the bottom of the problem.
I was finding that when going off the wind I was having to put a lot of pressure on my back foot to keep stability. Yesterday it was really nice 15m conditions and flat so I had a play about with the rear strap. I put the rear strap back back to one screw from the rear and the front of the strap I put back 2 holes so the strap was tighter.
At first it felt odd as I was wider on my stance but upwind and more importantly, downwind, the ride was faster and much more stable. I didn't have my GPS on but I felt a lot faster and was more stable.
I guess more weight over the back is what's needed in my case. I am using the board that came with my Spotz 2.
Nice review Tone. I felt the same way after upgrading from Spotz2 to Tuna. The fuselage/ mast/ wing junction was so much stiffer that it was immediately noticeable how much more stable it was and tacks and gybes were definitely easier. I look forward to trying the Shark, but I am really happy with the stability/ carve-ability ratio of the Tuna so I don't want to trade in too much more turnability since the stability is already good enough for me but I'm more surfer than racer.
