Yesterday I was pulling the boat off the water when I noticed the back center bunk board floating down stream! @#%#@$%%# I found 5 other bolts that were backed out completely or completely stripped from the wood.

I fixed it temporarily by moving the board an inch down and putting new lag bolts in but was very surprised that boatmate trailers (at least 2009) uses lag bolts versus nut/bolt or carriage bolts.
