CUPA Bow and Stern Thrusters

Technical descriptionAdvantagesAvailable optionsQuotation request

  • CP 40
  • Specially developed for ships or boats with a length of up to 10 m. The battery voltage is 12 Volt. Thus this model can be used in almost any ship.

  • CP 50
  • With its thrust capacity of at least 50 kg, the CP 50 can be installed in vessels of up to 14 m long. If the CP 50 is to be used in a 12 Volt installation, a series-parallel connection can be delivered.

  • CP 90
  • For ships of up to 18 m a rigid and reliable bow propeller with a thrust of 90 kg is available. Even when installing a CP 90, there is no extra loss of space in the bow of the ship.

    Since the CP 90 derives from the CP 40/50, all the advantages in these models are also present in the CP 90.
