Innovative hulls for fast ships

The Parametric Fast Hull
The "pfh" is a new hull for planing and semiplaning ships developed for minimum power requirements, very low fuel consumption and outstanding manoeuvrability.
This innovative hull is successfully used in a pilot vessel on the river Elbe and demonstrates these advantages in daily operations.

FeaturesAdvantages
  • deep V forward, concave bottom aft
  • airfoil shaped hull
  • pressure distribution counteracts stern down trim around hump speed
  • suitable for monohulls and multihulls
  • optimal for Fn > 0.8
  • Not suitable for very high speed > Fn=1,5
  • Very low power requirements compared to conventional designs
  • Superior seakeeping behaviour
  • Low wash
  • Very low draught
  • Very good manoeuvrability
  • Predestined for water jet propulsion
  • Very spacious aft
