Thanks for putting this up.
I'll say it again, I and a large portion of the SI crowd have a different idea of what performing on a surfboard means. Like I said earlier, you have a go-fast, go-straight board and in your mind that is the epitome of efficiency. That's fine with me.
I think the surfer's idea of performance in this video have more in common with a lot of the SI users. In the video at 1:36 Beano tries a couple times to make a front side turn up the face of the wave. He tries this unsuccessfully then moves back further on the board to try again and still can't do it and finishes out the ride by jumping over the wave at 1:45.
Later, when Jay is on the board he seems to be riding further back on the board as well and getting bumped around pretty violently but still holding on at 3:18 you can see he is trying to trim up to find the high line and at 3:24 attempts a backside turn down the wave and the board proves to be too unstable for him to complete the turn. The later rides show him trying to carve but unable to as the back of the board is too deep in the water.
I know that these guy obviously don't know how to ride this board as you stated earlier. You ride closer to the nose than them. However, this video and their surfing also serve as examples of how the board they're riding, that shares similar design principles to your other boards, is able to catch waves and trim but fails when a carving turn is attempted.
Early on in the Naval Architecture of Planing Hull by Lindsay Lord he writes of the early Japanese and Italian PT boats with 1800 HP that "took ten boat lengths to turn, with speed falling off badly during the turn." We see evidence of this with your videos. These surfers attempted turns and were punished for it, you trim but attempt no turns. We've seen this many times through the videos you've provided.
Again, as I've said earlier, there is a problem with the definition of performance. In my opinion, your definition of performance is riding a wave for as long as possible with minimal movement. My definition of performance would also be riding a wave as long as possible but meanwhile, I try to see the top and bottom of the wave and with a powerful turn in there if possible.... throwing buckets if you will. That's just me and my level of progression right now. If you are at the top of the game for the boards you're making and riding how do you see them progressing? I see people riding modern surfboard doing backflips now. Where is the future performance of your designs going?
