I did a seven finner @ Surf Systems in 70/71. It was way too loose, by the then standards of ride performance. Did not persue it beyond that one board. Box placement similar to yours, but closer to the tail.
how great is surfboard design, youguys did this 30 years ago and someone is doin it now, still always lots to learn, we'll never know it all, plus sooo many variables and potential combinations.....some are looking to add more fins and some are goin towards less or no fins...I think now we are in some sort of surfboard design revolution...happy times.....
