Hello everyone.
I've been thinking about welding up everything that is clamped with a U-bolt on my tinny trailer. Not solid continuous welds but decent tacks. What do you think?

Re: Weld trailer?

Are you ever going to need to re-rig it? I wouldn't weld stuff that is clamped so that it can be adjusted.

Re: Weld trailer?

The fastening relies on the clamping force. Even with welds, if the U bolt breaks, it's still going to get loose..

Re: Weld trailer?

after you finish adding extra foam to the boat and have nothing else to do....

On a serious note, the little bit of give for bumpy roads in a bolted/clamped attachment might help it last longer than a rigid weld. And as a saltie, I avoid welds b/c they rust first.

Sounds like this is a EZ loader galvanized trailer? (I ask because my EZ is all clamps & u-bolts) You can't weld on galvanized, it puts out some nasty fumes.

Re: Weld trailer?

However you can grind off the areas and weld away. If you plan on this trailer only working with your boat, then by all mean weld it up and you will never have a broken "U" bolt to worry about. I like that idea of all supports being welded on and never having to worry about bolts breaking or "U" bolts slipping and such. If you adjust everything to fit your boat and then weld it all up, how can that ever change? You need to protect yourself while grinding off any galvanized areas, but folks should use breathing protection anyways when grinding anything... Just my two cents for what it is worth... :cool:

Re: Weld trailer?

It's a Trail Rite not an Easy Loader and is painted. Don't know if it is galvanized.

......welding up everything that is clamped with a U-bolt on my tinny trailer.............................It's a Trail Rite not an Easy Loader and is painted. Don't know if it is galvanized.

Yes you can! and YES it puts out "nasty fumes"!!


I have a Trail-Rite ............You'd know if it's galvanized......paint doesn't like to stick if it is......

If you're welding the bow stop to the cross-member (2 U-bolts there) holding the winch you're probably ok.

The bow stop is not welded so you can adjust the position of the boat on the trailer to change the center of gravity (basically, tongue weight)

Once you get it where you want it, you'd never have to change it again and you could probably weld it.


It's really not necessary though, It usually doesn't get very wet or submerged, and would probably not get corroded. (those U-bolts are [or should be] hot-dipped galv.......and if they're not, get new ones)

I think I have U-bolts on my axles. Don't weld anywhere on your axles or they'll eventually break.... I also wouldn't weld on my horizontal longitudinal frame channel.........especially on the bottom....... they flex a LOT with a heavy boat and any weld could propagate a crack.

This has lasted for 30 years. I had the option of welding the bow stop post to a plate then using U-bolts to hold it to the tongue. I elected to weld it directly to the trailer. I don't remember my reason.

My welds are a bit sloppy but they are sound with good penetration.

We call those booger welds.

I hope you didn't pay much for that weld job. Not sure why you think there is good penetration on those welds, especially that front brace.

Re: Weld trailer?

The reason I was thinking of doing this is because my keel roller came loose and when I floated the boat it fell off and I didn't notice it. At first I thought it had been stolen, but I think it fell off. Bad maintenance on my part. The new one I installed, I loctited the nuts so I hope this is good enough to hold them tite. The other reason is for a better ground for the lights.

Ayuh,.... Even welding don't fix poor maintenance,...

You could probably weld your keel roller on but again, you're welding to a structural cross member (albeit on the top....so it might be ok) There's nothing wrong with u-bolts holing your hardware on though. Just use "nylock" nuts on the new one (loctite works too)

I wouldn't weld on a trailer just to get a better ground. Rewire your trailer with ground wires and use marine grade crimp connectors.

Re: Weld trailer?

You have to be very careful welding on trailers. I would have never welded the bow stop shown in Frank's picture since that is a load carrying beam and subject to cracking. At least its on the top of the steel tube.

For what its worth...bolts are superior to welds
