Re: Boat loading crooked

I upgraded the trailer on my last boat and the rollers were perfectly in line with one of the ribs on the bottom of the boat. It was allways crocked with the rib on one side or the other of the roller. I had to adjust the rollers to get it straight. If you look at it from the back with the boat on the trailer, can you see anything on the bottom of your boat interfering with some part of the trailer, either plank or roller to make it off centre?

Re: Boat loading crooked

I see nothing out of order on the trailer except the planks on the side that is low measures about an inch higher than the other side.The boat and trailer are pertty much as new. I'm thinking planks need adjusted like you did with your rollers,just not sure which way to go in order to raise right side.

Is your boat a flat bottom or a deep vee? Going on the trailer cocked means that it is not centering as you load it. Move the bunks between two ribs if you can and set them to equal height.

Notice how on this trailer I cut the bunks to match the strakes of the hull. Now the hull settles between them quite nicely.

Re: Boat loading crooked

The quick answer is to move the bunk on the low side, toward the keel.

The thorough way to do it takes a little more time.
Make sure bunks are parallel to each other.
Adjust to the same height.
Position them so they are the same distance from the centerline of the trailer.
Easiest to do this with boat off trailer.
So take your tape measure, wrenches, and a string to stretch down the center of the trailer, and head off to the launch ramp.

Then load it up and see how it sits.

Re: Boat loading crooked

Thanks for the good info. I think I can jack the boat up on one side in my shop and move the bunk down before I head for the ramp. Is their any rule of thumb about how far the bunks should be out of water before you start to load? I realize alot of boats load different. Mine is a semi-v 21 foot fish rite with fairley wide bottom?

Re: Boat loading crooked

Most of my trailers are about right when the tips of front bunks are right on the waters edge.

As for adjusting the bunks, it's much easier to adjust after you're at the lake with boat in the water. Makes for easier testing too. Load, check, if okay go have fun, if not, adjust, repeat- but go have fun anyway even if a couple of tries doesn't quite make it!

Re: Boat loading crooked

How far in the water are you backing the trailer?
Try loading with the trailer not so deep in the water.
A little more cranking involved, but workes for me on both roller and bunk trailers.
It bugs me seeing a boat crooked on a trailer.

Re: Boat loading crooked

I have a few thoughts: 1) It's not worth the effort to try and readjust the bunks with the boat still on the trailer, jack or no jack. Go ahead, bite the bullet, and float your boat at the ramp so you can work on the trailer in the parking lot. It's just so much easier.

2) Go ahead and buy the nuts, bolts and washers you will need to replace; then buy at least 25% more. Many folks go into this sort of job thinking that they'll just reuse their old hardware but I learned the hard way: it's a lot easier to cut off the old hardware and just replace it. You will waste a tremendous amount of time trying to undo rusty hardware and then you will still have old nasty hardware. You can do better. And of course buy the extra 25% because once you've put your boat in the water, you won't want to leave the site for any reason. Better to have half a dozen too many bolts than be shy one.

3) If you're going to go to the trouble of replacing the hardware on one side, why not do both? Just replace the hardware on the last bunk one piece at a time rather than removing the whole bunk. Then you won't have to make any adjustments. You end up with all new hardware with no weak side. My experience doing this suggested that 3/4 of the total time spent was on getting the first bunk swapped out and adjusted. Replacing the nuts and bolts on the second bunk only took a little while longer.

Let us know how you resolve this, however you decide to go. We'd like to hear about it... it's how we all learn.

Re: Boat loading crooked

One other option is to put side posts on your trailer so that the boat centers more easily. Also, with the guide posts you can see the position of your hull from inside the boat while pulling onto the trailer (i.e. 3" space on each side from guidepost to boat rub rail).

I REALLY like tall guide posts. While they help in loading, they are a huge assistance in backing your trailer. There is a point where the boat is going down the sloped portion of the ramp but the truck is still on the flat portion... the boat just disappears. The taller guide posts help prevent that.

Re: Boat loading crooked

One thing I do when retrievieng is to back the trailer in until the bunks are all underwater, then pull out until the front edges are just poking up. That gets them all lubed up so to speak for best sliding when winching/powering on.
