Hinckley was the first to bring the marine space the world’s first fully electric luxury yacht in 2017 (Dasher), and now the Maine builder is back with a new hybrid upgrade for its iconic Picnic Boat, which can run in full silence with its trademarked SilentJet technology.

“We know our clients want what’s next, and they also want common sense solutions,” says Geoff Berger, CEO of The Hinckley Company. “The electric Dasher turned heads as all our new models always do, but the practicality of going any distance on electric, given the best current technology wasn’t ideal for our clients.

“With SilentJet, you can travel farther with the hybrid diesel system than with Dasher’s electric platform. Furthermore, we learned that electric-powered water jets are much quieter and produce less vibration than traditional propellers. To deliver a truly silent cruising experience that feels almost like sailing, we knew our water jet propulsion system was the best fit.”

Hinckley started conceptualizing a hybrid solution shortly after the 2017 launch of electric Dasher. Ongoing conversations with Twin Disc led to collaborating on the project, and the team developed the final was integrated into Hinckley’s JetStick control system and featured automatic components that no one had brought to market before.

“By collaborating with Hinckley to implement a complete hybrid solution, we advanced our development with a proven builder who embraces electric and hybrid technology,” said Mike Gee, Vice President, Hybrid Engineering. “Twin Disc focused on Hinckley’s needs and tailored our technology and software to provide an automatic mode that seamlessly manages diesel/electric operation. The functionality perfectly complements Hinckley’s already existing user-friendly control system.”

The SilentJet technology maintains the standard of excellence found in all Hinckley products. Quiet propulsion and less time lost at the fueling dock make SilentJet the best way to spend time on the water with family and friends, the company says. With SilentJet engaged, the Picnic Boat 40S’s cruising speed is 7 knots. Range is at least an hour (at 7 knots, and up to 90 minutes at 5.5 knots), and the Picnic Boat 40S cruises at 35 knots (depending on load) under diesel power.

“With SilentJet, you glide away from the dock and cruise through the harbor in total silence,” says Scott Bryant, Hinckley’s vice president of sales and marketing. “When faster speeds are desired or the battery requires charging, the diesel engine comes on automatically, replenishing the battery in just 30 to 45 minutes. Since all the electrical loads on the Picnic Boat can be supported by the battery while at anchor, there’s no need for a noisy generator. It’s a complete paradigm shift in the onboard Hinckley experience.”

The company, founded in 1928, has a long tradition of innovation in yachting. From the early use of fiberglass in the Bermuda 40 in the 1960s, to the development of the first recreational joystick control (JetStick) on the category-defining Picnic Boat in 1990s, it has endeavored to combine the latest technology with cutting edge naval architecture.
