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?

Appreciated

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,
