Not to one of my boats, but I've seen it happen with a bunk trailer, before. Or, I should say, I've seen the aftermath. Not pretty. Imagine what happens when a board breaks away from the metal mount that it's secured to.
Don’t have to imagine,
Happened to my aluminum boat this past summer. Took the boat out a week before vacation for a shake down run. Loading it it seemed odd. Once home I discovered the two back bunks had broken free. Fortunately nothing bad happened to the boat.
Could have repaired it for about $150 but I just said screw it, too old to be playing that game anymore so $1,100 later I had a new trailer under it for a worry free trip.
when I got back I sold the old trailer for $500 as is.
So $600 got me a worry free rig for a number of years ahead.
I don’t know how obvious it is but the new trailer is 2’ longer which made backing it, dunking and retrieving the boat noticeably easier. Trucks rear tires don’t get near the water. The price difference between a 14’ trailer like this 15’ boat once sat on and a 16’ trailer was just $50 so it was a no brainer.
The Grady’s trailer cost me $4,800 with all its bells and whistles. I was happy to sell its old trailer for $500. I think I made out pretty good on the tin boats trailer purchase and sale.
Come to the conclusion lately that’d id rather spend the day on the water than working on stuff.
