Large pontoons and tritoons are long, wide and heavier than they look. We build custom aluminum pontoon trailers with bunks set to your tube spacing and axles rated to your loaded weight, including triple axle builds for the biggest boats.
Built to your tubes
We measure the distance between your pontoons and set the bunks and center guides to match, so the boat sits where the builder intended and loads straight. Our build sheet includes the bunk spacing and center guide measurements for pontoons, so you can measure at home.
Ready for the ramp
Choose surge or electric over hydraulic disc brakes, aluminum wheels, a spare tire and mount, side guides and a bow stand ladder. We've built and shipped pontoon trailers from California to Hawaii.
What goes into every ABTrailers build
- Aluminum I-beam frame sized to the load, from 7.5 in to 10 in, so the frame never rusts.
- Galvanized torsion axles with removable, replaceable trailing arms, rated to the boat's loaded weight plus a safety margin.
- Marine disc brakes with aluminum calipers and stainless steel pistons, surge or electric over hydraulic, plus Synflex non-corrosive brake lines.
- Carpeted bunks (2x6 up to 4x10) set to your hull's deadrise, on aluminum uprights and cross members.
- Stainless steel fastener package and sealed LED lighting.
- 3-year standard warranty and our corrosion-free guarantee: a custom aluminum trailer is built to last at least three times as long as a painted or galvanized steel trailer.
How a remote custom build works
- Tell us about the boat. Year, make and model, length, beam, deadrise and loaded weight (fuel, engines and gear). Our online quote builder walks you through it.
- Send a few measurements. If you have a trailer now, a handful of measurements from it (bow eye to tires, coupler size, tongue length) tell us how the boat sits. No trailer? Your boat's specs are enough to start.
- We design the trailer to the hull. We choose the weight rating, frame, axles and brakes, and set the bunks to your hull's shape, then send a written quote.
- We build it in San Bernardino. Pick it up at our shop, or we arrange delivery and freight, including crating and ocean shipping to Hawaii and Guam.
Your boat never has to come to our shop.
Questions owners ask
Do you build tritoon trailers?
Yes. We set the bunks to each of your three tubes.
Does a big pontoon need a triple axle trailer?
Sometimes. We rate the trailer to the loaded weight plus a safety margin; heavy tritoons often need three axles.
Can you ship a pontoon trailer to Hawaii?
Yes. We crate trailers and arrange ocean freight to Hawaii.
