Sure I would be very interested. But I'm talking about rocks. Do they operate airboats in rocky shore areas? When I see them on TV they are always flying over marshy shorelines. We don't have marshy on my beach.
They try to avoid hard surfaces, but I have seen my neighbor go across his shell driveway and another guy drove his airboat right up a concrete boat ramp. The coatings have to be pretty tough to stay when blasting through sawgrass, but I have no idea how they would really hold up for your use.
Thought they used catfish gland system I hear Oracle used the idea in the previous AC on the Monster. The tough coatings these days all seem to be grippy vs hard and slick. The coating needs to be flexible enough to let the aluminum flex when being beached without cracking and breaking the coating also. But 120lbs a simple big wheeled cart which after beaching and unloading, you slide it up on the cart then Bob does his best Ox beast of burden imitation and wheels it up above the high tide line.
