The next pics of the tractor and boat are very interesting. The beach is such that the boats that want to launch must travel a wide beach area to get into the water and it is quite dangerous with a car or pickup truck. These tractors hook up to the owners boat trailers go out and wait for them to come in . We think that they are talking by radio to set this up and as they come in. You can see the driver and the red on the back is the guy waiting for the boat to come and then he jumps into the water and hooks the boat on. After the boat is hooked on the tractor moves out and takes them to shore where they transfer the trailor and boat onto the owners pickup truck and away he goes. This all happens within 3 to 4 minutes. They are doing this all day long. Taking boats out and bringing boats into shore.
