Surfing Waves

Hi.

I was wondering if anyone bought a Paddle Board and uses it also as a long board on a wave.
Does anyone do this? If you do, is it too hard to maneuvere when riding a wave because its so long?

Thanks.

BTW Im a new surfer.

I surfed a 10' Laird "Performance" SUP.. if there is such a thing? the waves we around knee high.. it was fun for a little bit. I would rather have a dedicated long board though its do-able...
