2026 Williams Jet Tenders 345 SportJet

The Williams Jet Tenders 345 SportJet is an 11-foot fiberglass runabout built to serve as a high-performance tender for larger yachts. Powered by a single 90 hp BRP Rotax engine, the boat combines a sports-oriented hull design with jet propulsion for responsive handling and shallow-water capability.

The compact layout accommodates up to five people—driver and four passengers—in a focused, dynamic package. The boat's beam of 5.67 feet and overall footprint allow it to fit on davits or be towed behind mid-sized yachts without excessive weight or storage demands.

The hull is fiberglass throughout and runs on gasoline. The jet propulsion system and sports-tuned design make this tender suited to spirited operation while maintaining the maneuverability expected of a dedicated support boat.
