Version 2.0
My son and I worked on it for about 4 hours, spent another $160, so my dock has now cost me $280. I didn't have to waste anything from V1 except the foam noodles. I dropped the L shaped re-barb down to the lowest point, hammered the base down a few more inches so it is now about 3-4 inches above the water level. Maybe could have gone down another 2 inches.
Made a frame out of 4x4 eight feet by 6 feet. Since the bottom of the pontoons are not flat, I put five 8'6" 5/8 pipes across the frame, using 2x4 blocks on the outside sets, then 1x4 on the first set inside and nothing in the middle. Came close, but the curve is so severe, the first set of rollers could be 2 inches higher
I think it is closer, I put PVC over the ends of the steel rods hoping they would roll, but that didn't work out. Almost seem like I need bearing to get them to spin when the boat is being put on.
Sliding the boat on was much easier than lifting.
I do plan to add a wentch to allow me to get it on the platform by myself.
Things I learned:
1. Due to the curve in the bottom of the pontoons, I need to add another block under the first set of rollers.
2. May need to see if I can get some bearings to make the pvc roll.
3. Might want to remove the block on the rear set of rollers to make getting the boat out of the water easier, just use it for loading and not support once it is in place.
4. Need better fasteners to hold on PVC, what I got just isn't staying on well.
5. Because I am on a calm lake that doesn't get much wave action, I might want to go lower or add an additional roller that sticks out behind the platform at water level.
