Product Description
Achilles SU-18 Super Utility Inflatable Boat (2026)
The Ultimate Professional Powerhouse for Extreme Missions.
The Achilles SU-18 is the flagship of the Super Utility series, engineered for those who require the maximum possible capacity and durability in an inflatable craft. Spanning 18 feet with massive 24-inch tubes, it is constructed from Heavy Duty Two-Layer 1680 Denier Achilles CSM (Hypalon). Whether for commercial diving, military transport, or large-scale rescue operations, the SU-18 provides an unmatched 4,630 lbs load capacity and a stable platform for up to 11 persons.
Unrivaled Durability & Engineering
- Maximum Fabric Strength: Features two layers of 840 x 2 (1680 Denier) Hypalon fabric and four-layer seam construction for ultimate puncture and abrasion resistance.
- Rock-Solid Flooring: Deluxe self-locking aluminum and fiberglass floorboards combined with heavy-duty aluminum stringers create a rigid deck capable of handling extreme engine torque.
- High-Speed Stability: Rated for a 90 HP long-shaft motor, the SU-18 utilizes a deep air keel and large diameter tubes to maintain a dry, stable ride even when fully loaded.
- Mission-Ready Hardware: Equipped with 6 heavy-duty lifting handles, reinforced lifting points (hull and transom), and cargo wear patches for industrial use.
- Professional Safety: Includes a full-length splash guard with safety grab lines and dual self-bailer valves for rapid water clearance in rough seas.
