Nasdaq-listed Lindblad Expeditions has opted for Norway's Ulstein Group for its new expedition cruiseship.

It has signed a deal to take delivery of a firm vessel in the first quarter of 2020, with an option for two additional units.

The Finansavisen daily reported the price for the ship at NOK 1.1bn ($134.6m).

The shipowner is promising the world's "foremost" expedition vessel, designed to venture into polar regions.
