Hydrogen powered performance.

The 13m Chase Zero boat has been styled for VIPs of the AC37 with a luxurious interior cabin for high-speed transfers, race spectating and race support. With high-speed performance (50 knots), and exceptional visibility, it will serve as an incredible spectating platform.

The interior can be customized to meet client needs or match race boat aesthetics, and is equipped with a head compartment, fridge, and sink, as well as air conditioning for climate control.

The Chase Zero boat currently has seating for 8 in custom-built carbon race seats.

Developed by Emirates Team New Zealand and using Toyota fuel cells, this foiling chase boat has achieved speeds of over 50 knots during trials, and delivers comfortable, eco-friendly cruising at an impressive 30 to 35 knots.

Constructed in full carbon, Nomex and structural foam, the 13m boat has a weight of 5,600kg, a draft of 2.2 metres, and a 4.5-metre beam.

The two Toyota Hydrogen fuel cells are housed within each hull and deliver 80kW’s of power each. The powertrain cooling system is via a seawater pick-up located at the front of each foil-strut torpedo, with two pick-up pumps per hull. The port and starboard main foils are connected via a central wing foil spar and the single rudder features an elevator with adjustable rudder rake.

The power is harnessed with fly-by-wire joystick controls in the main console, alongside the navigational equipment, VHF, AIS, and system monitoring displays.

Performance

To date, Chase ZERO’s top speed is 50.3 knots. This was achieved on Day 9, 29 April.

The boat takes off and fully foils at 19 knots.

Whilst travelling at 25 knots boat speed, Chase ZERO is able to perform banked turns with a radius of 48 m.

Experience with Chase ZERO has shown that an operating speed of 30-35 knots is highly efficient for hydrogen use as well as comfortable for the crew.
