Frequently Asked Questions (FAQs)

1. What size boat is the 5.7m Galvanised Trailer (ATM 1400kg) designed for?
This trailer is ideal for boats up to approximately 5.7 m in length, including larger aluminium runabouts, centre consoles, bowriders, and similar craft that require a stronger trailer with a higher load rating.

2. What does “1400kg ATM” mean and why is it important?
“ATM” stands for Aggregate Trailer Mass which is the total maximum weight of the trailer plus the fully loaded boat and gear. A 1400 kg ATM rating means this trailer can safely handle heavier boats and equipment without exceeding its design limits.

3. Does this trailer come with brakes?
Yes, trailers with a 1400 kg ATM rating typically include a braked axle setup, which improves safety and legal towing compliance when hauling heavier boats.

4. Is the trailer suitable for marine use, including saltwater launches?
Yes. The trailer features a hot-dip galvanised steel frame that provides excellent corrosion resistance, especially important if you’re launching regularly in saltwater environments.

5. What standard features are included with this trailer?
Standard inclusions typically include an adjustable winch post, keel rollers or skids for hull support, galvanised axle, wheels with mudguards, LED trailer lights, safety chains, and a jockey wheel for easier maneuvering.

6. Can the trailer be adjusted to fit different boat hull shapes?
Yes. The adjustable roller/skid configuration allows you to fine-tune the trailer to suit many hull shapes and sizes, and optional accessories like spare wheel carriers or upgraded lighting systems may be available.
