Double check that Trailer??
I have just been to a nasty accident
Chap towing his Rib for a day out at Weymouth.
He got about a mile from home when the trailer uncoupled from his towbar
he had a "safety rope" which snapped.
Trailer and Boat collided head on with a car coming in the oppposite direction.
Fuel in boat ignited and when I got there the whole lot was a fireball in the middle of the road.
Luckily the driver managed to get out with no more that singed hair and shock but, believe me, it could have been a lot worse.
There was nothing left of the Rib except a charred outboard.
Moral of the story is check and double check that coupling and use a wire strop for safety - make sure its in good condition and up to its job!
Live every day as if its your last and one day you will be spot on!!
