well several years ago i was fishing northfork on Rough with my wife , cousin and his girlfreind when we watched a guy backing a traier down to the water he sets the break gets outand is guiding his wife in. this is a big ski boat 28-30 foot with a lot of power no doubt , so he is standind on the tounge of the traier with whinch strap in hand guiding her in and everything was going great. as she is sliding up the trailer the boat seemed to slip out of gear and wide open up the trailer past the whinch and hits him and pins him right up against the back of a van. while hes pinned up on the back od the van with bow slamming in his chest shes is freaking out and still going strong. luckily there was several guys standing aroung who were riding with him and one jumps in the boat and backs off the throdel so the others can get him out of there, he was hurt no doubt but when they got him out from under the bow he went in the water after his wife. yelling and screaming at her while the other guys calmed him down. this guy could have been injured a lot worse and possibly killed and you could hear his wife screming she didnt know what to do and it was the first time she had ever loaded a boat on a trailer so it wasnt entirely her faught
