Details and Specifications of Four Crew Boat Cats (This design is available for construction)

“Bue Daryn” is a slightly larger and faster version of the 18m, 50 passenger crew boat catamaran design. Powered by twin cat 3412 engines (1100 h.p.) and doen 220 water jets, the vessel has a top speed of 32 knots.

In order to meet the owner’s contract requirements and in a race against time to get the boats up to the Caspian before the only access closed due to the winter icing over, the builder decided to ship “Bue Naryn” and “Bue Daryn” in a semi completed stage and finish building her in Baku.

The builder sent the construction squad to Baku to complete the vessels, the team of 10 to 15 men plus 10 local azuri laborers took a total of 14 weeks. Other Australian companies to assist with the project in Baku and send men were Doen Waterjets and TMQ Marine Electronics and Lloyds Australia.

Sea trials were very successful in the 1.5 to 2 metre conditions with the catamaran handling well with speeds up to 32 knots.

All vessels were purpose designed by Paul Birgan in conjunction with the experienced owners ‘Bue Bulkers,’ to meet the challenging conditions of the Kazakhstan oil fields.

  • Low draft of 900mm fully loaded.
  • Large aft’ open work deck with additional strength to enable load carrying activities.
