The 5.7m Galvanised Tandem Boat Trailer – ATM 2000kg from Sea Raider is designed for transporting boats ranging from 5.2m to 5.7m (17 ft – 18.7 ft), making it ideal for heavier aluminium and fibreglass hulls. Built on a wider 1895mm chassis, this trailer provides increased lateral stability and balance during towing—especially important for high-speed or long-distance travel.

Fitted with tandem axles and a mechanical override braking system, it ensures smooth braking performance without requiring an electric controller. This trailer can be built as either a roller or skid version. It features heavy-duty tube side adjusters that allow for quick and precise roller alignment, providing optimal hull support and easier launching and retrieval.

Frequently Asked Questions (FAQs)

1. What size and type of boats is the 5.7m Galvanised Tandem Trailer (ATM 2000kg) suitable for?
This trailer is ideal for larger, heavier boats up to about 5.7 m in length, including centre consoles, bowriders, cuddy cabins, and other vessels that benefit from a tandem axle configuration for better stability and load support.

2. What does “ATM 2000kg” mean?
“ATM” stands for Aggregate Trailer Mass, which is the maximum combined weight of the trailer plus the fully loaded boat and gear. A 2000kg ATM rating means this trailer is built for heavier loads and more demanding towing requirements.

3. Why choose a tandem-axle trailer over a single-axle model?
A tandem axle offers improved load distribution, stability at speed, better handling, and reduced sway, especially when towing heavier boats. It also generally provides a smoother ride and better support over rough roads.

4. Does this trailer come with brakes?
Yes, trailers with a 2000kg ATM rating include a braked axle setup, which enhances safety and helps meet legal towing requirements when transporting heavier boats.

5. Is this trailer suitable for frequent marine use, including saltwater launches?
Absolutely. The trailer is built with a hot-dip galvanised steel frame, which offers excellent resistance to corrosion and makes it suitable for regular saltwater launching and marine environments.

6. What features are included as standard?
Standard features typically include an adjustable winch post, keel rollers or skids for hull support, twin galvanized axles, wheels with mudguards, LED lights, safety chains, and a jockey wheel to make launching and retrieving easier.

7. Can the trailer be adjusted or customised for my specific boat?
Yes, the roll rollers/skid positions can be adjusted to suit different hull shapes, and optional extras (like a spare wheel bracket, upgraded winch, or lighting plug type) may be available depending on your needs.
