• Bunk Trailers: Support the hull using padded wood or plastic boards. They require driving or winching the boat into deeper water to launch and load, but offer superior hull support and lower maintenance.
• Roller Trailers: Use cylindrical rollers to roll the boat off and on. They allow launching and retrieval in shallower waters or steep ramps, but require more moving parts maintenance.

• Single Axle: Ideal for lighter boats (typically under 3,000 lbs / 1,360 kg). Easy to maneuver by hand and lower maintenance costs.
• Tandem Axle: Essential for heavier loads. Provides better stability at highway speeds and safety in the event of a tire blowout.

Inspect wheel bearings annually or every 2,000 miles (3,200 km). Repack them with marine-grade grease at least once a season, especially if launching in saltwater.

Yes, thoroughly wash the frame, brakes, axles, and lights with fresh water immediately after every saltwater immersion—even if the trailer is galvanized or aluminum.

Inflate tires to their maximum PSI listed on the sidewall, park on wooden blocks rather than cold ground, or use tire covers to block UV rays. Alternatively, elevate the trailer on jack stands to take the weight off the tires.

Target a tongue weight between 10% and 15% of the total gross trailer weight (trailer + boat + gear). Too little weight causes dangerously instability (trailer sway); too much overloads your tow vehicle's rear suspension.

Regulations vary by region, but most jurisdictions require independent trailer brakes on rigs with a Gross Vehicle Weight Rating (GVWR) over 3,000 lbs (1,360 kg). Surge brakes or electric-over-hydraulic brakes are standard
