The HDPE strips and StarBoard-covered bunks made moving the boat off and back on the trailer much easier than the bare plywood deck and carpet-padded bunks did.

Great article, Chris.This past summer, I had to remove the bunks on the used trailer that came with my 16’ Lund. The carpeting had held moisture over the years and the boards had begun to rot in places. I replaced the bunks with new pressure-treated wood and used HDPE instead of carpeting. I can echo everything that you mentioned plus would add that there was no longer any hidden rot for me to worry about. HDPE is the way to go.
Sounds like a great idea. Any idea how the surface of the HDPE holds up over time?
I have metal guards on the bottoms of the two boats I’ve dragged over the HDPE on the trailer deck. There is some scuffing, but I don’t see that the plastic is being worn away. A search on the web turned up indications that HDPE is broken down by UV light, but I suspect that process take a direct exposure to sunlight over a long period of time. I have a decades old Nalgene bottle that’s made of HDPE and it’s still in good shape. If you have a boat on the trailer and the boat is covered, the HDPE will have little UV exposure and should have a long life.
I was struggling with the same dragging problem and upon reading your piece on HDPE I contacted the supplier and am waiting on my order. Thanks for the tip, Chris.

I have been building and modifying trailers for small boats for 35 plus years. Flat-bottom boats don’t work on the standard commercial boat trailer.
For plastic strips try ultra high molecular weight polyethylene, UHMWPE. It is also available in strip and solid form. It is used for the bearings supporting the masts and periscopes on submarines. Many people use it to make woodworking jigs. It may be better for trailers and has a weird soft but tough property that will protect a hull from impact.
I have used the cheap PVC trim boards that are sold for plastic houses at Home Depot. Super cheap, light and easy to rout and cut.
A single roller at the back of the trailer helps with the loading and usually ends up with just the skeg on it.
whatever helps us get the boats to and from the water
Carpet on bunks left out in the weather can stay damp and eventually cause pinhole corrosion in aluminum hulls and soften or bubble some paints. Plastic runners on bunks dry out better, another advantage.
Great info! My small cedar-strip lobster-style boat has a flat bottom, so I have carpeted bunks on my trailer. However I also found it a bit hard to get the boat on and off. Last fall I added strips of my grandkids’ no-longer-used super slider to the bunks. I figured if it slides over the snow so easily, the boat should slide over it easily too. It did! Pulling the boat (about 1800 pounds loaded) up was a breeze. I don’t know how long these thin sheets will last, but hey, they were free! Since my experiment worked so well, I will probably follow your article’s advice and eventually upgrade to the HDPE strips when the super slider wears out.
This is a fantastic idea and will be going this route on an upcoming trailer rebuild/modification for a flat-bottomed Pacific Power Dory. Thank you for putting it up!
Chris,
I am looking for a trailer to carry our 17′ Mackinaw-style row boat. It is to hard to load the Trail-Ex without getting into the water. I am looking at a Karavan or Shorelander basic bunk style trailer. I would cover with plywood like your trailer is. What make is your trailer?
The trailer in the article is one of two drift-boat trailers that I found on Craigslist (Seattle). Here on the West Coast, lots of river anglers use the dory-style drift boats and their flat bottoms work well on a plywood-decked trailer. Both trailers have hinged tongues, so the beds can tilt for launch and retrieval, but I’ve never needed that feature. The trailers seem to be manufactured by a lot of small shops. Neither of the trailers I have come from a shop listed on the web.
If you just need strips, check out the plastic lattice sold at home improvement stores. It works well and is relatively cheap. It can easily be cut to the shape you want and it is bendable. It will take carefully countersunk screws.
John mentioned plastic lattice a few years ago and I installed a piece on my fltabed trailer. It works very well. See “Five Practical Tips.”
