I have a 2018 Lund Rebel XS boat with a 75 HP outboard, on a Lund trailer. I have had problems loading my boat. I had a terrible time this week loading it, no matter how deep or shallow I loaded the boat as I loaded and unloaded it perhaps 8 times that day. I found that the bunks bolts had come loose during this trying time. So I tightened them and tried another 2 or 3 times to load the boat. Basically, what happens is that when I start to crank the winch to load the boat as the boat gets closer to the winch the rear end of the boat tilts towards the port side of the trailer until it touches the wheel bumper (see picture attached). I am looking for advice as to the amount of slant (in degrees) the bumpers should have (if any) to make the loading of the boat improved.
Sorry for the photo I cannot upload it vertically.
Any other suggestions would be appreciated.
