It is a surf ski just like many others.
The optional gull wing is an interesting development, but having not seen it in real life, I can only speculate.
I cannot imagine it being anything but liability in big surf.
In flat stuff it is not required.
It will add weight.
I see it as a good training aid to get beginners onto an elite type tippiness without having to swim.
As for the rest of the boat, I have never seen one in real life, so there is no way to comment on it's attributes.
The basic dimensions are not even listed on their website.
But what I can say, is that for every strength that has been engineered into it, there will have been an accompanying weakness.
Stable or fast, pick any one.
If you want a versatile boat, then the entry level boats from many manufacturers will suffice.
Your posts suggest that you are a competent K1 paddler.
I cannot see that you should have any problems getting on any elite ski out there.
All of the current crop of elite skis are very similar, the basic physics tends to point to the same solutions.
So just go try out a few and pick one.
Follow the path of the independent thinker. Expose your ideas to the dangers of controversy. Speak your mind and fear less the label of 'crackpot' than the stigma of conformity. And on issues that are important to you, stand up and be counted at any cost.--- Thomas J. Watson
