Gulf Shores marina on Bayshore Ave has the largest supply and it's not all that. Maybe a dozen boards and skates, a few ropes and hadles, vests etc. m They are Mastercraft dealers.
Jet Set surf shop has a whopping 1 (one) wakeboard stashed behind the skateboards.
The cable in Fort Myers is very good, Revolution Cable Park.
I'm in Marco and we run the boat quite often. But it aint exactly an X star.
The best board shop locally is my garage or Dustin Beatys garage.
Hit up Dustin for a lesson while here. He is very good and has all new gear, boats etc..
Just google wake board marco island or something close.
