2026 Highfield Sport 420

The 2026 Highfield Sport 420 is a 13.92-foot aluminum rigid inflatable boat built for dual duty as both a premium yacht tender and a capable family day boat. Its marine-grade aluminum deep-V hull combines strength with minimal maintenance—no gelcoat concerns, no water absorption, and superior impact resistance compared to fiberglass alternatives. Powered by a 60-horsepower Tohatsu four-stroke outboard, it reaches 40 knots top speed and cruises efficiently at 24 knots, offering strong acceleration and responsive handling across a range of conditions.

The layout centers on practical comfort and functionality. A forward sundeck provides relaxation at anchor, while an integrated console accommodates electronics. Seating is arranged for family and friends, with ample dry storage compartments and a self-draining deck. The inflatable tubes use ORCA Hypalon material for long-term UV and saltwater durability. Optional features include a tow post or roll bar for watersports.

Lightweight construction makes the Sport 420 easy to tow and launch, a genuine advantage for trailering and management. The boat's modest size and strong power-to-weight ratio keep handling predictable and stable, whether anchored or maneuvering in turns, making it approachable for new boaters while remaining capable enough for serious coastal cruising and shallow-water exploration.

An EZ Loader trailer is included with this boat.
