Aluminum Boat Trailer WP1315 - Single spring axle - Suits boats 4m to 4.6m.

WP1315 Boat Trailer Overview

The WP1315 is positioned as a single‑spring‑axle trailer designed for small to mid‑size tinnies and runabouts. Its configuration suggests a focus on simplicity, corrosion resistance, and ease of maintenance.

Key Specifications

• Boat suitability: 4.0 m to 4.6 m hulls

• Construction: Stainless steel components, keel roller plus skids

• Overall trailer length: 4.8 m

• Tare mass: 260 kg

• ATM (Aggregate Trailer Mass): 1500 kg

• Price: $6,990

This combination of a relatively light tare weight and a 1500 kg ATM gives you a generous payload buffer for boats in the intended size range.

How these specs translate in practice

• Single spring axle: Best for lighter boats, easier servicing, fewer moving parts, and lower long‑term maintenance costs. Ride quality is simpler than multi‑axle setups but perfectly adequate for the size range.

• Stainless steel components: A strong advantage if you’re launching in saltwater. Stainless hardware significantly reduces corrosion risk compared to standard galvanised fittings.

• Keel roller + skids: A hybrid setup that supports the keel while stabilising the hull. This is common for aluminium boats and lighter fibreglass hulls.

• 1500 kg ATM: Well above what a 4–4.6 m boat typically weighs, even with fuel and gear. This gives you margin for safety and towing stability.

• Price point ($6,990): This sits at the higher end for a single‑axle trailer in this size class, likely reflecting the stainless components and overall build quality.

How it compares to typical trailers in this range

Most 4–4.6 m boat trailers:

• Run 750–1,200 kg ATM

• Use galvanised rather than stainless hardware

• Cost $3,500–$6,000 depending on brand and features

The WP1315’s higher ATM and stainless components place it in a more premium bracket, aimed at buyers who want durability and long-term reliability rather than the cheapest option.
