The Williams Jet Tenders team penned the DieselJet 415 as a can-do tender that can ferry up to six passengers. The RIB’s 110 hp Yanmar 4JH diesel engine works in concert with a jet pump to deliver top speeds of almost 35 knots. It comes standard with about 24 gallons of fuel capacity. All DieselJet 415s are hand-built and sea-trialed, and they have contemporary-styled dashboards with center-fitted 7-inch Raymarine Axiom multifunction displays that are flanked by on-dash stowage cuddies.

The RIB is designed for portside boarding and includes an on-tube step pad and a boarding pole—the latter of which can be stowed in a recess under the bow cushion. Owners can choose from a lengthy options menu, including an upgraded nav system (a 9-inch Axiom MFD with AIS and VHF radio), AC power, a freshwater shower and a Fusion stereo. A low-profile version of the tender has a folding helm station and a removable wheel that lower the boat’s overall height to just 3 feet, 3 inches.

Whom It’s For: The DieselJet 415 RIB is designed for owners of expedition and semidisplacement yachts in the 75-foot range who want to carry a single fuel type aboard their main ride.


PictureThis: It’s a gorgeous day on British Columbia’s Desolation Sound. The mothership motoryacht is safely anchored, but the short-set crew wants to go exploring. The DieselJet 415 is launched, and soon you’re all cruising toward Teakerne Arm Provincial Park to harvest oysters and spot waterfalls.
