Hey noob don't get tied down on small details.
I used to see the shaper for Zuma Jay pushing boards that were totally different rail configurations side to side lengths and tail configurations!
You will go nuts trying to make your first board perfect.
Do your best!!
I will tell you anything that floats and paddles well will work and look at all the guys shaping flat planks of wood and ripping on them.
Also look up the Orange thread you can always sand it all down and reshape it.
My first board was something to behold almost flat rocker pulled in tail super sharp rails in the back going to very blocky rails in the front.
It had dips and wobbles a terrible looking glass job and I over shaped the deck so it dented real easy.
I worked on the fins for years grinding them off and putting them back on and it worked with every fin configuration I tried.
It looked like Frankenstein by the time I was done!
My friends teased me and told me it was a piece of crap but I not only made it work I surfed it fairly well none of them could surf it worth a damn which made me laugh even more because they all thought they were good surfers.
It was hard to paddle but was the fastest quirkiest board I have ever owned.
I shaped it to surf one and only one wave the small point break at Zeros a small point/reef beach break in Malibu.
I had it almost twenty years and recently sold it at a garage sale for almost as much as it cost me to build it.
So do your best shape it, glass it, ride it proudly, learn from your mistakes and most of all have fun!
My only other bit of advise is to have someone to help you glass it because no one ever mixes the resin right the first time and nothing sucks worse then having it kick half way through the process.
If you lived in San Diego i would have been happy to help my glass jobs while still ugly have never failed me.
Did I mention they are ugly?
