Heavy offshore boats are where stock trailers fall short. We build custom aluminum sport fishing trailers with bunks set to your hull's deadrise and axles placed for your loaded weight, so the boat launches and loads cleanly and tows straight.
Built for salt water
Sport fishing boats live in salt water, and so do their trailers. Aluminum frames, galvanized torsion axles, stainless fasteners and marine disc brakes with stainless pistons keep corrosion off the trailer. Add aluminum wheels, stainless steel brakes and sealed Vault hubs for even less upkeep.
Options anglers choose
- Slide tongue to keep your tow vehicle out of the water on steep ramps (requires electric over hydraulic brakes).
- Aluminum side guides and 2- or 3-rung boarding ladders for easier solo loading.
- Welded or adjustable V bow stop, spare tire and mount, and a trailer utility box.
Sport fishing boats we've built for include Radon, Force, Grady-White, Pacific Custom, Innovator, Amato and North River boats.
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
What size trailer does my offshore boat need?
We rate the trailer at your boat's loaded weight (with fuel, engines and gear) plus at least 2,000 lb, then choose axles, tires and brakes to match.
Do you build trailers for Radon and Force boats?
Yes. Radon and Force are among the boats we build for most often.
Which brakes are best for a heavy boat?
Electric over hydraulic disc brakes give smooth, proportional braking and are required for a slide tongue. Surge brakes are simpler and need no brake controller. We'll recommend one for your boat.
