Converting a trailer to a swing-away tongue

Anyone done this? My trailer is galvanized, and I don’t weld, so I’d use one of the bolt-on adaptors.

My buddy bought a place on the coast and it has a shop bay with a high door that’ll fit my boat... which is awesome... except my boat/trailer is too long. Should fit with a swing away tongue (by mere inches) but I can’t/won’t afford an $8k new trailer right now, plus, I recently completely rebuilt my hubs and brakes on my unit.

Anyone do this? Happy with the result? What brand kit did you choose?

I replaced my broken Fulton hinge with this.


only because it came with a hinge in the tongue when I bought my boat and trailer.

After going through this I would never cut a trailer tongue on purpose. YMMV

No, it’d be within mere inches WITH a swing away tongue. It’s a 24’ (outside measurement) deep bay; so more like 23’5” on the inside. That’s right where a swing away trailer puts me.

Since it’s going to be so close, before I do anything I’m going to take my own measurements at his shop.

Any chance angling the boat might work? Just an idea. Good luck. I tried ordering one of those upgraded hinges mentioned later in this thread and still haven’t received it - almost a year later.

I faced the same issue with my boat in my garage and converted it to a swing. I've never regretted installing the hitch but it hasn't been without issues. Storing the boat inside is so much better for it and you. Not having to remove your gear everyday saves you a ton of time and energy in addition to making everything secure.
I was about to go with another Fulton but instead decided to go with a swinger. As others have said it's much better built but also much more expensive.
As a result I'm selling the Fulton I was going to install.

I’m a machinist, so as long as I can get the trailer in my lathe, I’ll be ok. 😗

I think I’m gonna go for it- once I get my buddy to re-measure the space. At best, it’s going to come to mere inches, but if we can angle it even a little, it should fit. And the payoff is huge. It’s a 2-bay shop but has a stepped slab to create more headroom for the big bay; that’ll restrict how far we can angle it, unfortunately. But I have a good feeling about this.

This trailer has seen a LOT of salt; modifying it is no crime, trust me. That said, what should I treat the cut edges with?

Could you fabricate a tongue that slides in and out? I've seen that set up on sailboat trailers.

Friend brought his 21' boat to a welder. Tongue was cut, a box receiver - next size up of square tubing - was welded to the boat side of the cut, two holes through box and inserted tongue, bolted together with case hardened bolts, rock solid Just a couple of minutes to remove or install, and hella strong, believe it cost him about $300 to have done.
