Private Marina Service

The aft end of each ship transforms into its own dock, making it easy to set off by paddleboard, pedal boat, or even water ski from the retractable marina platform. Of course, you can also embark on one of the expert-led excursions (part of the optional Ventures by Seabourn) kayaking in the Amazon with a marine biologist, or whale watching in Alaska’s Misty Fjords.
