just finished shaping my first stubby hull it is just shy of 6’ width is around 23" tail 15"… the real meat of the belly starts about 16-18" down. no side bites, im just going to pop in a single fin box, wondering about how far up my fin placement should be and also what size fin. i know im going to use the greenough 4a but unsure about size 9, 9.5? any insight would be greatly appreciated.

I have no advice but that thing is sick!Where is the outline photo?
Yes nice board. How does putting a 10.5" FU box anywhere between 8.5" and 9.5" up from the tail sound? Check the archives, and there might be better info. Keep in mind, most flex fins have a fairly narrow base so you can adjust accordingly until you find the sweet spot. then mark it so you can remember it in the future. with my single fin setups, I take the fin and lay it on its side with the base lined up with the stringer, and move it up or down until about 25% of the fin is hanging off the rail of the board. I heard this somewhere and this fin placement has worked for me.
By the way, do you live on the central coast(specifically arroyo grande)?
rad! great adivce, thanks a bunch. im actually based out of florida, currently up the coast in charleston, sc though.
thanks dood! i appreciate it. ill post the finished product soon
Install the box and try the fin in different positions but you might want to go 7" 4a. I have a 6’10" mp hull and use a 7" 4a about 3/4 the way back w/ side bites. I tried the baord w/o the bites and fin forward but did not like the no drive while hulling down line.
