I’d spin it round and it’d look better, a pulled in tail will sink a bit on slow waves. Sizewise it depends what your used to, I’d go smaller than that if your used to shortboards or fish. I’m a bit heavier than you and surf a 5’9", 21",2.5" I’ll go shorter and thinner next time .
You should change the tail to a diamond tail and instead of just making the tail wider 1’ up make the actual tail wider. Also the nose seems a bit wide. But that is just my 2 cents
i made one recently for a customer. Attached should be the aku shaper file i used for my template. Maybe you can mirror some of the curves if you like them. The board is said to go really well, nice and smooth and picks up waves with ease. I made it as a single fin but a two plus one would probably be your best bet.
As far as rocker goes i would recommend shaping by eye to begin with. Find a blank that has a nice rocker curve in it and retain that curve so it looks pleasing with a bit of extra flick nose and tail to finish off. Going off one measurement on the nose and tail won’t really help in getting a nice curve throughout. Standing the blank against a wall will give you a good perspective and just keep picturing the water moving along it uninterrupted.
once hatched! no, thats a good one… i’ve always classified 7’ + to be getting into the mini-mal range. Once they start getting a straighter oultine through the middle and losing that curvey egg shape they begin to resemble a mini mal more and that seems to begin to happen past 7 foot (unless its 23 inches wide).
