Then again, I have heard several people talk about the potential corrosion my boat can incur from the aluminum hull sitting on carpet, wet with salt water and wrapped around pressure treated wood. I haven't seen any damage, but the boat is new and I'm not crazy about the idea of it happening.
I looked at several different bunk glide products, but realized I would have around 100 bucks in it by the time I was done. There had to be a better, and cheaper, idea. One I could build instead of buy.
Step 1: PVC Is Slippery
I bought a piece of the trim board and twenty 1 1/2" stainless steel screws at my local building supply yard. That's all I needed, and at $30 dollars, it was considerably cheaper than any commercially made bunk glides I had seen.
The piece of PVC trim I bought was 18' long and the bunks on my trailer are about 7' each, so first I cut it to length. Then I cut a slight bevel on the front end of the pieces and lopped the top corner off the rear ends. I then sanded both cuts, making the rear into a rounded bullnose. I also planed and sanded down both top sides for the length of the boards so there were no sharp corners in contact with the hull of my boat.
The photo shows the trim piece after the cut but before finishing the rounding.
Step 2: Screwing and Countersinking
Step 3: Mounting
Step 4: Finished Product
This is the trailer after the addition of the bunk glides.
I am very pleased with the end result. Before, it was hard to launch the boat and equally hard to recover it. There was so much friction that I was afraid that I was going to pull the bow eye out of the hull.
Now, the boat slides easily onto the glides and I can crank the winch with one hand.
I could have bought a similar thing, but I did this for much less money and very little effort.
Note: After two years, the PVC is holding up well and the screw heads are still out of the way.
