Back's getting a bit creaky, so figured a kneel up board would help.
So tried a mate's board today, and sure enough, back comes out a lot better. Picking up waves was easier, but on a steepish wave I found the board was running away from me and I fell off the back. I think the weight of the board may be the problem, also makes it harder to turn.
This board was a fraction under 9kg, 9'4" X 23" X 3". I'm thinking of knocking up something similar, except shorter, thicker and lighter,

Maybe a bit under 9' same width 3.5" or 4" thick and closer to 5kg than 9.
I think that should paddle as well, turn easier, and not take off on it's own down a steep wave.

Any thoughts? Can a long board be too light, maybe a problem in strong off shores, getting blown off the top?

Oh yea, I'm only 65kg.

Enjoyed my session today, although I surfed like a kook, I don't think it would take me too long to remember how to walk the board, get my foot back to turn and try some nose riding again.

Just need to know what to build and why.
