Surfing Waves

Saw this and thought I could use it as a beginner board. Have. Plenty of experience in board sports so I have pretty good balance and heard funboards are slightly more maneuverable then a longboard.

Not a bad place to start but depends on your height/weight.
If you're tall and/or heavy, that'll be a bit too small to start out with. An extra bit of volume isn't going to hurt.

Don't worry too much about manoeuvreability yet - the first part of learning to surf is all about learning to paddle, learning to catch waves, etc., and board-sport experience won't be any help for a while. The biggest risk is going out, catching nothing, getting frustrated and not having a good time.
So go big - you'll be upgrading your board as you progress anyway.

I'm 5'8 about 145. I read that the size needed for me was a 7'2 so that's why I went with a 7'6 instead. Should I just go 8'0 then? Still learning how thickness and what not affects ride quality and what not.

Those size guides are hopeless

For your size, 7'6 – 8' would be a good start. The 7'6 would probably be manageable, but an 8' would be easier. With a cheap pop-out board like that, you don't need to worry about the long-term – once you've got the basics down, you'll want to upgrade anyway

Lol! Alright cool. I was thinking the same thing. when I get pretty confident in myself on a board Ill upgrade and give my wife the funboard for her to learn on.
