“WAVE-PIERCING” trimaran, WPT: the concept and some applications. Victor A. Dubrovsky

WPC differs by high performance, big deck area, developed seaworthiness.

Achievable speed of WPC is restricted in principle:

Fish view of WPT.

Towing model, design speed

Aerodynamic tests

Some examples of applications: 1-t racer, up to 150-200 kn; 20-t mini-ferry, 70 kn, Sea State 3; 100-t ferry, 90 kn, Sea State 4; 600-t long-range passenger ship, 130 kn, Sea State 5 – 6.

Racing boat is dynamically stable

Mini-ferry has additional bow wing:

Proposed ferry for line St.Petersburg-Helsinki

Possible trans-Atlantic ship:
