roller to bunk trailer--Who has done this?

[willy]

What is down the center (keel) when you first pull her up, what is helping to center the boat? I saw one keel pad in the pics but it looked low.

All I can say is WOW!!...I fully expected to see ALL the roller brackets gone, replaced entirely by bunKs and a couple of rollers for centering and beam protection...the flat bunks running front to back of all the brackets is a real stroke of genius!!...talk about SUPPORT!!...and easy to see why she centers so well loading...did you see that done or is that all your idea?...either way...GREAT!!...

[step up here]

yes sir, its a good thing i saved my rollers. now i have two options. looking at the pics is a huge help. MANY THANKS on that one.

The keel rollers on there are ones that were previously on there with the rollers--I just did not remove them---the boat gets nowhere near them--so not needed--The 4 boards are measured as to slide it in place off of the bottom (chines)of the boat.

The idea to use the roller brackets was mine---I took measurements and built it--then went down and loaded the boat out of the lake---brought her home and jacked up the boat in place, then moved the boards into place to make them tight on the chines---1/2 to 3/4" clearence.

The boards are allowed to swivel by being on the roller assemblies bothfront back for them to conform to the hull front to rear and pivot center to outside to conform to the V shape---

I put the trailer about 6 inches in front of the fenders underwater and drive her on--centers automatically about 3/4 of the way on---then pull her out and crank in about 4 inches as the bunks level out when you stop floating the boat---has worked spot on everytime since I got her done last year.

Cost estimate--under $100
Time--about 6 hours


Glad you guys like it---I will get pictures with the boat off this coming week when I am out fishing off the coast---Ling Cod and Sea Bass!!

I am in need of replacing my keel roller, it is tearing up the keel big time. You can see the pic of it in my profile where the roller sits at. I put that there to replace a broken pvc centering... thing. We thought it would be a good idea to replace it with a keel roller. It turned out to be a not so good idea. I like the bunk boards for the keel that tsubaki has on his boat, i just need to see them better or even find out who makes them.
One place wanted me to use a swiveling bunk board bracket to fit on there, but didnt say how I would attach it at or if I can angle it to fit the keel.
Any Ideas?

If I had a roller trailer, I'd convert mine TOMORROW...THE WHOLE THING ARTICULATES TO CONFORM TO THE BOTTOM OF THE HULL...YOU MIGHT HAVE REALLY HIT ON SOMETHING...Damn caps Lock...

A properly fitted keel roller will not tear up the keel. The whole reason for the roller is to prevent the keel from being torn up. I'm willing to bet that your keel is hitting something as your boats launching or retrieving. But the roller (if it's adjusted correctly) should never do anything except allow the keel to glide across it.

How big a roller was it and did it spin properly?...sometimes they stop turning on their shaft...

The keel roller is a 12" thermal plastic roller from yates. I can tell where it took off the gelcoat due to some left over paint embedded in the roller.
After the weight of the boat sitting on the roller for a while it developed a flat spot, and its starting to bend making it hard to roll.
So I got a few choices left, either replace it with a self centering polyurethane roller or do away with it all and do the brackets and bunk board. Or add in another cross beam aft and keep the roller to help center the boat. Either way I am looking at 100 bucks to fix this problem.
I noticed in the past that the 3x3 tube the I beams connect to sits almost 4" forward of the roller cross beam. I can tell it has done some damage in the past. I've looked at other Aluminum trailers on the internet and seen that this tube doesn't extend nearly as far aft as mine does. This is the reason that we had to keep the keel roller so it doesn't contact the tube. I'll go this weekend and get the boat off of the trailer and take more pictures.

Yeah...once that roller won't roll freely, it becomes a problem...the pin going thru the roller is't strong enough to support the weight of a V20 on it's own....had the same issue...never tried this, but considered putting TWO rollers back to back on the same cross-member to double the support...I did the two bunks you describe....more $$ but it solved the problem...
