I've currently got a 9' 6" longboard, and I want to buy a short board that I will be able to duckdive easily. I weigh 165.
I know that there are several variables: Length, width, thickness, buoyancy, my experience level, etc.
But assuming I can get pretty good at this, please give me some guidelines as to length, width, and thickness. I will probably pick up a junker at a garage sale to try it out, and I'd like a guideline such as "If you get a board that is less that ___ in length, ___ in width, and ___ in thickness then you should have no trouble duck diving."
Thanks!
