Been in Orange Beach area for 20 yrs never seen that for trailerable boats. They have fork lifts at zeke's, sportsman, romar habor and a big boat crane at orange beach marina, but why pay when you can back in the trailer.
So you back up to the hoist, hook up and drop in the water and the cost is? do you bring your boat or is it kept on site and the marina does it for you for a price? I see it for some applications in the pics just curious.
