Williams Jet Tenders is expanding its product range with two new jet tenders. With the TurboJet MX series, the manufacturer is launching two models aimed primarily at owners of yachts between 40 and 70 feet. From August 2026, they are set to replace the existing MiniJet 280 as the entry-level model.

With the TurboJet 280MX and the TurboJet 320MX Williams is introducing two new models that are priced below the existing product range. As with the brand’s other tenders, the two new models are also fitted with a jet propulsion system rather than a traditional outboard motor.

Compact and with 60 PS

The TurboJet 280MX is 2.79 metres long and can accommodate three adults and one child. It is powered by a BRP Rotax Ace 903 engine with 60 PS (44 kW). This is said to enable the tender to reach a top speed of 36.5 knots or 67 km/h.

The price is 17,299 pounds, which is equivalent to around 20,000 euros. According to Williams, the 280MX is also around 30 per cent lighter than comparable jet tenders from other manufacturers.

More space and 90 PS

The TurboJet 320MX is slightly larger. It is 3.19 metres long and can accommodate four adults and one child. The engine produces 90 PS (66 kW), which is said to enable speeds of up to 39 knots. The price is 19,995 pounds, which is approximately 23,500 euros.

With both models, customers can choose between white and grey hoses. The hoses are made from multi-layered Hypalon material, which, according to the manufacturer, is particularly resistant to UV radiation and salt water.

A more competitive offer for a changing market

According to Williams, the new MX series is its response to the changing situation in the yacht market. Sales figures have declined in recent years, particularly for yachts between 40 and 70 feet. The company cites the significant rise in prices due to inflation as one of the reasons for this.

The new tenders are therefore expected to be around 20 per cent cheaper than comparable models with jet propulsion. Mathew Hornsby, sales manager at Williams, sums up the development: “For many owners, you’d have to go back to 2017 to find a new Williams tender in this price range.”

The MiniJet 280 is being phased out

With the launch of the TurboJet MX series, Williams is also phasing out the MiniJet 280 as its entry-level model. Production of the current model is set to end in September 2026. Thereafter, yachts in this size range will be fitted with the new TurboJet models as standard.

According to Williams, there are currently more than 5,000 of the brand’s tenders in use worldwide on yachts between 40 and 70 feet in length.

Now available to order

The two new models can now be ordered via Williams’ global dealer network. Despite the lower price, the manufacturer has no intention of compromising on quality or workmanship. Both tenders continue to be produced at the Williams factory. According to the company, they undergo the same quality controls there as the brand’s more expensive models.

Ole Puls was born in Schleswig in 1999. He quickly swapped the football pitch for the Schlei and grew up sailing a wide variety of dinghies and tall ships. From his grandfather's self-built wooden opti and a Europe to a 49er and an X362 Sport, there was a lot to choose from. After leaving school, Puls decided to train as a boat builder at the high-tech shipyard Knierim Yachtbau in Kiel in 2016. He successfully completed his training in 2020 and stayed at the shipyard as a bachelor. In 2022, he decided not only to build boats, but also to test them. Since then, he has been working for Delius Klasing Verlag in the Test & Technology section of BOOTE magazine. The training he received and the eye for detail and quality of workmanship he acquired help him immensely today. Even though he is a regatta sailor with heart and soul, he feels right at home on motorboats and enjoys separating his professional and private lives and yet combining them. Because we all know one thing: there is simply no better place to be than on the water.
