Got the 2013 model I think, look at my site for full review: windsurfing.lepicture.com/

A bit stiff, wide stance, prefers smoother waters, lack a bit of drive. If you sail powered up then it's not a problem. Super light, seems well built. Still on stock straps.

I ride it as a single. (23cm and 4.7). Nice backloops, pop is so-so.

That's a recent one. Oops totally forgot about volume!?! What volume?

I'm guessing generation 12, which is what they are at currently.
Volume matters too though, as they are quite different from one size to another.

I have an 86liter, generation 1. :)

Yeah, the Goya One 12 thang threw me off as well but the blue one posted above in a 105 liter is what I'm looking at. Latest current model.

I have a very old 105 Goya freeeide, it's actually a freewave, brilliant. Light, well built, turns incredibly well (better than the 77L freewave), not as good with big sails (6.5+) great with smaller sails (4.7-6.0).

If the new one is anything like that one, incredible board. Usually 105s are universally loved!

. Got out on the one12 115 Kate on the old 106 and 4.7

I like the mini tuttles no stripped allen screws. I have a 81 custom 3, a 106 one, and a 115 one, they all are very fun to ride. No dents or dings in any of them and I am pretty heavy 95 kg. Double concave with quite a flat rocker. You just hop on the board and it's comfortable right away. Plenty fast, loose, jumps well. Just a fun all around board.

The fin tuning and choices seem a bit limited with MT for the side-fins and the odd, rewards, position of the PB centre fin...?

The MiniTuttle situation has always bothered me. Hard to get a good fin unless you import directly from the US. PB centre fin... same situation. There are no decent wave fins unless you buy MFC fins which again are difficult to get hold off... at least here in Australia.

I understand why they had to go with that strange offset Powerbox design and I suspect the vast majority of their customers never change the fin. But for people that regularly sail at reef breaks fins are somewhat of a disposable item.

K4 are great to deal with directly on their web-site, great service, they even reduced the cost for me in order to compensate for the import taxes.
(as UK are not in the EU anymore and I live in Sweden)

But the PB is in the "wrong place" for regular PB fins, you would have to get the special, off-set, one from MFC. On the older and smaller One-boards, they used a regular US box. This allows for more tuning, in terms of position, depending on the spot and conditions.

Here is a picture of the PB fin:

I have the latest blue 105. It's my lightwind waveboard.
the fin position is not an issue if you change the center fin for a more standard powerbox one, you'll just have a fin 2cm back, a little less turny and a little more easy to get going... except that this board is stellar in both planning/speed/upwind AND turning already, so that the difference in sensation will be negligible anyway.
I love this board, I'm 75kgs so it's a seriously big board for me, I use it with 5.0, 5.3 and 5.8 , and the best thing about it is the super confortable and smooth auto-pilot feeling that allows you to nail your entire repertoire eye closed . It is so easy going and pleasant to use, even in some fairly decent waves, it's ridiculous. A real modern "funboard". i had the 2020 105L before, the red and blue, and I really loved it too. The One12 does everything the 2020 One did, just a little bit better. They really enhanced its turning capacity, and made the ride smoother.
I also tried the new Quatro Power in 94L, and while it was even better in the top turn than the new One (snappier, to the point of deserving to be called a true waveboard imo) it really was not as good at getting planning in lighter winds.
