8'9" x 28 " x 4 1/4" (I'm 83kg)
It's got generous Rocker - heaps of Concave and low profile rails. Swallow tail and plenty of nose area.
Here's an experiment for you:
That Laguna board is 8'9 x 28 x 4 1/4.
Scaled down (divided by 1.41). You are riding a 6'2 x 19 3/4" x 3" Not too far off what you would ride as a shortboard at 85kg barr the thickness of which is blown out as you are not lying down to paddle.
My point: There is not much new to learn here, you want performance boards for the surf? you get a performance shortboard outline and scale it up. Bang. The amount you can scale up is reliant upon your balance, strength and experience. Do the maths with your board.....
There is room to reduce length further by exploring new ways to maintain volume without having to go too wide as (just as shortboards) if you go wide with too much rail outline you lack projection from turns, it's loose but you go nowhere.
I think about this stuff way too much.
