Could this work for SUP surfing?

Love the innovation, and I think the tail would make for a very stable sup.  I'll let some of you shapers chime in.

It may in some situations be ok at best but these finless boards just have too many downfalls overall.
Fins, besides being a source of drive and holding power are also the way we fine tune board's handling characteristics. I'd stick with a finned board.

No finless boards for me either. A fiasco just waiting to happen. Like piloting a boat and the steering cable breaks.

I played around with a finless race board, it's hanging on my wall. Works great, goes straight like it was on rails. and when you try to turn, it goes straight, like it was on rails. By the time you get hull dynamics to equal the stability of a fin, you have a very powerful, full-length, full-time stability machine. If you turn a fin a little bit it transitions from stabilizing the board to helping it steer. Not so with finless. It might be fun, but it's not going to be great.

Whenever someone says finless all I can think of is this........whole different level.
