Need Dim suggestions for single fin PLZ

I have a 7’3’’ clark blank. I would like to make a classic single fin, like the merrick single fin g2, or something similar. I need to make it about a 6’10" or 6’8". Can someone help fill in the rest?


Just throwing something out there…

16in nose and tail

21in wide

I’m not familiar with the traditional point break style single fin. But I like the outline of the ones that seem to have a fuller nose and narrow sharp pin tail. Just want to do something a bit different. Thought it would be a good project and excuse to foil a wood fin for it. Thanks,
