About this tender
The EvoJet 70 is the build we ask Williams for when the programme needs a full-sized jet tender rather than a compact runabout. At 7.1m and 2.65m beam, it carries thirteen people with genuine deck space to spare, and the Yanmar 4LV common-rail diesel delivers the immediate, lag-free response that jet propulsion is known for. Williams specifies this hull for motherships of 40m and above, and the proportions bear that out.
What sets it apart from a straight size comparison with RIB alternatives is the helm environment. A rotating bolster lets the driver work seated or standing; a single-lever throttle handles shift and trim together; and the Raymarine Axiom 9-inch MFD with depth sounder and chartplotter comes as standard rather than as a chargeable option. The 235 litres of distributed storage - behind the helm seat, port and starboard lockers, and a dedicated anchor locker - means the crew can run a practical day programme without improvising.
The optional folding carbon fibre T-top addresses the garage constraint that makes full-height superstructure impractical on many vessels. Stowed, it brings overall height down to 1.42m, which opens up tender garages that would otherwise rule out a boat of this beam. If your garage is tight on height but comfortable on width, that option is worth specifying at order stage rather than retrofitting.
Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
The 250 hp Yanmar 4LV is a proven common-rail diesel with a global service network. It drives a jet pump rather than a propeller, giving the EvoJet 70 its characteristic instant throttle response and removing the prop-strike risk in shallow or congested anchorages.
Storage is distributed across an easy-access unit behind the helm seat, port and starboard lockers, a centralised compartment, and a dedicated anchor locker. At 235 litres total, it is a meaningful figure for a tender of this size and reduces the need for deck clutter on a full day out.
The optional T-top is fabricated in carbon fibre and folds down to bring the boat within tight garage height constraints. It provides shade over the helm and passenger area when deployed, and its folding mechanism means the decision does not have to be made at the dock.
A Raymarine Axiom 9-inch multifunction display with integrated depth sounder and chartplotter is fitted as standard equipment. Twin chartplotter, AIS, VHF, and a Fusion audio system are all available as factory options, giving captains a clear upgrade path without third-party integration.
The adjustable seat bolster rotates to allow the driver to operate seated or standing at the helm. Combined with a quick-release adjustable steering wheel and a folding helm console with bonded windscreen, it gives the helm position a degree of ergonomic flexibility uncommon at this price point.
