Hi everyone,
I'm looking forward to shape my first own shortboard for waves from waist to overhead height. I first started with a single concave and quickly thought that I could make it end with a double for smaller waves with less speed . This is where things got really complicated. I thus ended up with two versions; one with a single concave, as I thought my imperfection would have less impact, and one with a single to slight double that left me with a lot of questions that I couldn't answer searching on internet.
In both case, I can't really tell if the depth and transition between concaves is in the right place so I could use some help.
Both boards have almost exactly the same dimensions and rocker, and even if the concave type is different, both have the deepest concave (almost 0.26") point slightly behind the middle.
Here's images so you can see all the specs. (the red line shows where the sections are made and the blue line shows the concave evolution)
Cheers,

Okay, what I do for this kind of board know is a single start at one foot from nose finish at front of back fin max depth at two feet+ from tail where I start a double barrel concave up to tail. I work it to make lot of angle at rail, harder to put fins but good feeling on wave.
Listen to lemat.
That which can be assorted without evidence was read in an illegal magazine.
Thanks for the advices.
So I moved the deepest point of the single concave to approximatively 2.3 foot from the tail where it switches progressively to a double concave with the deepest point between the front fins. I also readjusted the angle of the double concave that is now dominant at the rails and flatter in the center. (image below)
Does the rail profile and angle with the concave looks alright and do you think the concaves are deep enough? (3/32 inch (almost 0.1 inch) for the deepest double concave point and 0.235 inch for the deepest single concave point).
One last thing, do you think I should make the angle of the rail less sharp and more open? They almost seem a little too pointy even if the section is down around the front fins
Thanks for your time,
cheers,
Marc

I am a hand shaper so I don't be used to look at those kind of pictures... Double profile look good for me but at that point it's insert in the single. So overall deepness is more for me in general for short boards.
