Dynamic hydrofoil for low-wake, high-speed ferry

The Lady Swift, an aluminium catamaran coupled to a composite superstructure and a dynamic carbon fibre hydrofoil, was delivered to Bremerton on Friday, July 26, 2019. The vessel was designed by Teknicraft Design Auckland, New Zealand and will operate on Kitsap’s current cross-sound ferry route between Bremerton and downtown Seattle, alongside the recently delivered Reliance. The design of the new 78’ x 28’ vessel was based upon the successful ultra-low-wake Rich Passage 1 (RP1), built by All American Marine in 2011. AAM, the exclusive builder of Teknicraft Design in North America, was selected as the sole source to build this vessel.

“Lady Swift is not your typical ferry, it was built to be very lightweight and to fly smoothly through the wake sensitive zone,” explains Matt Mullett, CEO for All American Marine. “This vessel was strictly modelled on the proven hull design of Rich Passage 1 and Reliance, but additional enhancements and modernizations were added without hampering performance.”

The 78’ Lady Swift was designed to carry 118 passengers and travel at service speeds up to 36 knots.
