South America quiver

I’m planning a Chile/Peru trip next year and am looking to make myself a couple of single fins to take over, specially set up for surfing clean long left points.

I’m going to have one all rounder for headhigh-overhead days and one step up for up to 2x overhead days.

This is what I’ve drawn up on BoardCAD so far for my all rounder single - a 6’2 x 18 3/4" x 2 3/4". 13 1/2" nose, 13" tail, 3" of nose rocker and 2" of tail rocker. Just a rough idea of what I was thinking of doing.

Flat entry with slight double concave vee starting in the middle and running through the tail.

Have only designed a few boards so any feedback on what I could improve would be great, and also any suggestions for what I could do with the step up single fin would be really helpful.

Cheers
