Facebook for business benefit - Please Advise . . .

Hi all . . . need some advice and opinions . . . .
I have a surfboard brand and design all legally registered and have been told it’s actually a very good business (and surfing) proposition.
I have been told that I need to get onto Facebook to further my cause;
So . . .
A question to you my honourable surfing guys and gals of surfing waves . . . . .
PRO SURFERS:
Does Facebook further you cause ?
PRO SURF COMPANIES:
Does Facebook further you cause ?
PRO AM SURFERS:
Does Facebook further you cause ?
Non Pro Surfers:
Does Facebook further you cause ?
Humble ordinary surfers and surf schools:
Does Facebook further you cause ?
Ultimately is Facebook worth the maintenance hassle to promote a young business?
All opinions and more than welcomed.
Hwyl’i chi [cheers]
