Review from a paddle I had today on the V12, on flatwater only. I normally paddle a Mako Millennium and the V12 is certainly more stable. Whereas the Mako wants to roll from side to side with very little resistance, the V12 doesn't. I tried the V10L immediately afterward and to me the stability felt the same, although a fellow paddler, who did the same, felt the V12 had slightly less.
Cockpit was extremely comfortable. I put a .5" pad in and it was great.. didn't try it without pad, but others had no complaints. Single footwell is awesome, definitely the way to go. Footstrap was nice, I kept it tight and the whole setup felt very similar to K1. I'm 6'2 with 34" inseam and did not have the footboard all the way forward. Not sure on its limit.
Plenty of space under the knee to get proper leg drive.
Did not feel like I was 'paddling uphill' or slouching/sinking into cockpit.
Deck cutaways are perfect. I spent the last 3 months on K1 and smacked the deck of my Mako often when I started back on it last week.
The bailer worked great. I kept it up (flush with hull) since it was flat water, but splashed water in to test and it drains very fast. Interestingly, it has a one way valve of sorts, so even if you have it down and are stopped, it only lets in water very, very slowly.
Speed was fine. Didn't seem any faster than the Mako Mill or Icon (I have both), but wasn't any slower either. It was Ultra layup (25 pounds maybe), so it accelerated easier than my poor man's layups. With the extra stability, I have no doubt that I'd paddle the V12 faster it certain conditions, able to apply more power to the stroke instead of balancing.
I want one.
