ZESST is designing and building hydrofoil vessels that fly above the water with zero emissions, zero wake, and zero compromise.

Why hydrofoils

The physics that make clean propulsion viable.

Zero emissions

Full electric or hydrogen fuel cell – both 100% clean. No CO₂, no NOx, no particulates.

up to 85% less energy

Hydrofoils lift the hull out of the water and eliminate hydrodynamic drag, the dominant energy loss at sea.

 

Silent & smooth

Flying above waves eliminates noise, vibration and seasickness. Closer to aviation than maritime.

Lower cost of ownership

Less fuel, simpler maintenance, no exposure to carbon compliance costs.

our vessels

Two platforms. Two markets.

Private vessel

Precursor

A 10.7 m (35 ft) hydrofoil yacht for up to 7 passengers, available with full-electric or hydrogen propulsion. Built for owners who expect marine-grade performance with the quietness of a private jet cabin.

PAX

A modular hydrofoil ferry, standard 100-passenger capacity, scalable up to 150 in extended configuration. Engineered to replace diesel shuttles on lakes, rivers and short coastal routes.

engineering

Aerospace discipline, applied to maritime.

Every subsystem is developed with the rigour inherited from Almatech’s 15+ years of space engineering – integrated with naval architecture and maritime expertise.

01
Propulsion

Electric & hydrogen

Two clean propulsion paths. Full electric for short urban routes; hydrogen fuel cells where range matters. Both silent, both emission-free in operation.

02
Efficiency

Active hydrofoils

Carbon-fibre wings submerged below the hull lift the vessel out of the water in motion, reducing drag and enabling high cruise speeds at low energy cost.

03
control

Flight control system

Aerospace-derived stabilisation with continuous foil adjustment. Perfectly smooth flight regardless of sea state.
