Stubby shortboard rocker

Hi

What would be the rocker measurements on a stubby 5´8 shortboard (Dumpster diver type) for small to medium size waves, waist to head high, beach breaks?
Nose rocker and tail rocker, considering it has a continous rocker, not staged, and a slight to medium single to double concave, nothing to extreme.

What would be the minimum and maximum rockers a board like this would work with?

I´ll try to upload a pic , lets see what you think about this design.

…use the US blank 6R nat

Hi reverb, thank you for answering… but I live in an island and buying a blank would be very expensive because of the shippng costs. I do have an EPS factory near by and thats what I use for my surfboards.

I dunno, looks like KS and Reverb are on the same page…or at least can be sketched on the same page. I understand not being near blanks.
