Description

Why the HRAB1315S H4 Full Alloy Trailer is the Ultimate Launch Platform

For smaller coastal boats up to 4.8m, weight and rust are your biggest enemies. The North Coast Trailer Spares HRAB1315S H4 completely eliminates saltwater corrosion concerns. Constructed with a rigid 100×50 marine-grade aluminum frame, this trailer will never rust out like traditional galvanized steel, protecting your investment for decades.
Built for Simple, Safe Highway Towing
Despite its lightweight design, this trailer doesn’t compromise on running gear. The high-capacity 7-leaf spring suspension provides excellent dampening over uneven regional roads. Paired with commercial-grade 185 70R14C tyres and striking custom alloy wheels, it tracks perfectly true behind your vehicle while adding a high-end look to your boat setup.
The front winch post serves as a complete command center, neatly packing your heavy-duty hand winch and an integrated spare tyre bracket right where you need it most. Durable, impact-resistant plastic fenders provide excellent protection against road debris without adding unnecessary bulk.
