Lund boat trailer

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.

Thank you

I have a Crestliner I transport on  trailer made by ShoreLandr. It has four bunks, two on each side. The bunks are mounted to a fixture I'd describe as a yoke which is bolted to the frame of the trailer. I've adjusted the mounting bolts on the front and rear yokes so that they are just barely snug. When the boat is off of the trailer, the bunk assemblies rock toward the centerline of the trailer under their own weight. As I load the boat, the bunks follow the lines of the hull and rotate outward thus centering the boat. If there is a strong crosswind or current I compensate by backing the trailer into the water a bit less. 

When launching, I back down ramp just enough so the boat floats off of the trailer. Usually the trailer tires will be submerged between 2/3 to 3/4. Make a mental note of the water level at the point your boat floats off of the trailer without assistance. 

When recovering, my tires are about 1/2 submerged (shallower than launch).

I drive onto the trailer at low speed. In gear, at idle, it usually moves about 2.5mph.

If I happen to be a bit crooked, I pause for a moment. The next wave or my wake hits the transom and usually causes the boat to settle in.

I hope this helps and doesn't seem too convoluted. Good Luck!

What was posted below, plus check your weight distribution on the port side. Also, they make self-centering rollers that help.

Same boat and problem when I first had my boat. Side bunks had like 4 to 6 inches of play on both sides. Solution was to get the boat dead center on the trailer. I able to drag it to center by grabbing the back side and using my entire body pushing off the trailer can inch my boat to center. Then move your side guide bunks, so they are within 1 inch of each side of the boat. Even on an uneven launch my boat now centers perfectly after moving the side bunks in.
