About SunStone Ships Inc

The expedition cruise vessel expert.

Knowing the right way to navigate has been essential to maritime activities since mankind’s earliest days on the sea. In the days of the Vikings, it was the ancient sun stone that provided this ultimate guidance and insight for waters across the globe. When placed in a direct line with the presence of sunlight, the stone would glow brightly. Even on an overcast day with the sun visually obscured by clouds, rain, or snow, the stone would light up when pointed in the direction of the sun, identifying a ship’s course.

​Today, with decades of expertise and hands-on experience, SunStone operates the world’s largest fleet of expedition vessels available on charter. SunStone is NOT a cruise company, but a provider of tonnage to cruise companies, tour operators and travel companies around the World. With the new building series, INFINITY delivered between 2019 and 2023, and BOUNDLESS to be delivered from 2025, SunStone will stay in front in the development of the expedition and small ship cruise tonnage.
