What Williams Jet Tenders does
Williams Jet Tenders Limited is a UK-based manufacturer of luxury jet-powered rigid inflatable boat (RIB) tenders, founded in 2004 and operating from two sites in Berinsfield, Oxfordshire with 140 employees. The company produces compact and superyacht tenders across six product lines — MiniJet, TurboJet, SportJet, DieselJet, SOLAS, and EvoJet (including the Electric EvoJet 70E) — under the Williams brand, and a separate superyacht specialist brand, Evene Tenders (Origin Series), launched in 2025. Its core technology is jet pump propulsion, which provides shallow water access, propeller-free safety, and precise low-speed manoeuvrability; the company also operates an in-house resin-infusion moulding facility (opened 2020) and integrates patented Petestep hull technology in the Evene range. Engine supply is dual-sourced: YANMAR diesel engines power the DieselJet and SOLAS ranges, while BRP Rotax engines power the SportJet, TurboJet, and MiniJet ranges.
The business sells bespoke-influenced hardware at quote-based pricing through a global authorised dealer network, with an in-house "Build My Tender" configurator, dedicated US distributor (Williams Tenders USA, Pompano Beach, Florida), and direct OEM relationships with yacht manufacturers including Sunseeker International. Pricing is not publicly disclosed. Customers are superyacht owners (>35m), yacht manufacturers (OEMs), and luxury leisure boaters; the company has built over 12,000 tenders cumulatively, with the 10,000th unit milestone reached in 2021. Regulatory certifications span SOLAS, Cayman Island Shipping Registry, Red Ensign Yacht Code 2024, and Malta Yacht Code 2025, and the company holds the 2024 King's Award for Enterprise in International Trade. Williams is a privately held, founder-owned company (Hornsby brothers and Roy Parker) trading under Williams Marine Group, with no disclosed external funding.
