Remember the trailer? This one, the one that almost killed us?


We left the shantyboat hull pretty complete. Now that the boat is ready to be flipped, we turn our attention back to the trailer.

It is really a rusty, janky old thing. Ive owned it for fifteen years or so, or sorta owned it since I bought it with Sean for our Burning Man theme camp, the Costco Soulmate Trading Outlet. Its been stolen and recovered, broken and repaired on the road. We used to haul that thing back and forth loaded to the gills over the Sierra Nevada Mountains, taking our lives into our own hands. Then we realized that if we stored it in the desert, we could save wear and tear on our mortality. So there it stayed for about ten years.

When the camp realized it could buy a shipping container and have it dropped off at their campsite every year without the hassle of dealing with That Trailer, the poor thing got abandoned for a few years out in the Nevada wilds. You remember that I drove out to the desert with Alex to rescue our friend the trailer, a trip with nearly fatal results.

So here it is, a 20 foot flatbed, maybe suited to my shantyboat, maybe not, needing suspension work, a coat of paint, deck repair, and maybe some repair welds.


The first thing I did was fire up my cutting torch and cut off the weird distinctive triangle things, and ground down the cuts. I always assumed they were there as a token gesture to structural reinforcement.


I replaced all the deck bolts that had rusted through, grinding off and replacing any that had loosened. The deck needed about 50 new bolts. This alone made the deck much more stable.


I gave all the metal on the entire trailer, top and bottom, a new coat of Rust-Oleum. I had to get suited up to prevent myself from being painted too thoroughly, climbing under the trailer and applying paint overhead.

It looked pretty good when I was done. Though crawling around under the trailer, I saw several places where the metal was cracked, principally around the lateral beam that joined the two pairs of leaf springs on either side.

For a while, Id been sweating how to make the skids that would hold up the boat. I considered using recycled railroad ties since I could get them for free at the local trainyard, but their height and condition were too inconsistent. Eventually I got a ridiculous deal from a friend at the local lumberyard who found me some 6x6 treated lumber seconds that had a barely perceptible twist or were split a bit at one end.


I positioned the skids so one set would lie just inside of the skegs, and the other set so they lay at the outside edge of the trailer, as far out as could be secured. I figured this would support the boat along the stringers as well as give it side-to-side stability, something I thought would be extra important as we were trucking down the highway.


I drilled bolt holes through the skids and into the support brackets under the trailer.


I put big long 8 inch carriage bolts through the skids. For extra measure, I painted the bottom and tops of the carriage bolts. Lawrence joined me for a bit and serenaded me with excellent banjo tunes.


To prevent the skids from damaging the surface of the hull, I chamfered the sharp edges of the skids with my skill saw.


I cut the ends of each skid at an angle to guide the skegs while the boat was being trailered. Though honestly, I dont think the skegs at the back of the boat will be anywhere near the skids, since that end of the trailer will be deep under water and the back of the boat high above it during a boat launch or trailering. But it seemed like a good idea.


Then I covered the skids with indoor/outdoor low-pile carpet, stapling and using roofing nails at the edges.


The result was surprisingly legit looking.


Then Jen and I sat on the trailer and had a beer.  Something about this trailer makes you want to sit on it and have a drink.  Whats that about?

Next, the superhero of heavy duty welding flies the trailer high into the sky and melts it with his heat ray vision!

We fretted over fiberglassing the hull so much, we put off beginning with this step for weeks.  We read and reread our instructions from Glen-L, Ken Hankinson Fiberglass Boatbuilding book, and anything else we could find.  We went over scenarios and thought of terrible things that could go wrong.  We thought it would be so harrowing and difficult, that in the end, it was a bit of letdown.

Heres where we left the boat last time.  Filled, shimmed, routed, sanded lovingly.  Lawrence came by a couple times and asked, "What are you building, a boat or a piece of fine furniture?"


Before we started the day, we had to wipe the whole boat down and make sure there was no sawdust, grease, debris, or anything anywhere.


But really, this was just the seal coat, the first of four or five coats wed put on the hull.  We wouldnt even get out the glass cloth until the next coat.

And now a quick primer on fiberglass:  Fiberglass is a composite laminate material.  The layer(s) of spun glass cloth or mat embedded in a matrix of polyester or epoxy resin are what gives it strength.

In some boats where the hull derives its strength from the fiberglass, it is typical to use alternating layers of mat (a loosely woven nest of randomly aligned spun glass) and glass cloth.  In our boat, the fiberglass covering on the plywood hull served only the purpose of keeping it watertight and creating a durable wear-resistant maintenance-free surface.  So we had only to put one layer of glass cloth between several layers of epoxy.


There are many methods of applying fiberglass to a boat hull, but they break down to the so-called wet and dry methods.  "Wet" means the fiberglass cloth (or mat) is laid over a just applied layer of resin and then "wet out" with more resin on top.  This sounded hectic. We imagined laying cloth over a wet sticky layer of resin and fighting wrinkles and having the cloth misaligned and pulling our hair out and getting sticky head to foot.

We were relieved to discover in our Glen-L instructions that they recommended the dry method.  "Dry" means simply that the first coat is rolled out without the cloth and allowed to set.  Then the cloth layer is laid out over this dry layer and more resin on top of that to wet it out.  This allows us to carefully align the cloth without the stress of either sticky goo or the ticking clock.


In this first seal coat, all we were doing was covering the hull with epoxy.  Kai mixed up big batches of epoxy and put them in paint trays for me to roll out with a dense foam roller.


Then Kai came around with extra resin and touched up spots Id hit too lightly and brushed down any air bubbles.  Because we werent mixing the resin with filler, it had a longer pot-life and so didnt tend to kick off early, even though we were mixing it in larger quantities.



The result was beautiful, though vaguely reminiscent of a horribly outdated style of 70s handmade varnished pine bedroom furniture.




Though it was a hot day in the barnyard, we were feeling pretty good about our work and the results.
