The Isles of Shoals Steamship Company has been operating for over 25 years cruising the Piscataqua River and Isles of Shoals. We offer a variety of cruises to suit nearly everyone. Whether it be with family, friends, co-workers, students or hosting a special celebration, our crew looks forward to welcoming you aboard. Come cruise with us and take in the breathtaking NH seacoast. The M/V (motor vessel) Thomas Laighton was named for a famous “Shoaler”, politician and businessman. As keeper of the Isles of Shoals Lighthouse with his family on White Island, Thomas Laighton later founded the Appledore House Hotel. This began the resort era of the Isles of Shoals and NH seacoast in the mid 19th century. The M/V Thomas Laighton is a 90’ vessel with three decks which is certified to carry up to 340 passengers. There are two enclosed cabins and an open air sundeck. We carry up to 150 guests for a seated dinner and up to 275 guests for a cocktail style cruise. We limit sightseeing cruises to 275 guests as well for comfort. The Thomas Laighton features three full bars, one on each level.

The Ledges Golf Club in York, Maine, offers you the finest public golf experience on the seacoast. In fact, north of Boston, this is definitely the first course you'll want to play. Rugged New England terrain frames an attention-grabbing par-72 layout where you may be distracted at times by the spectacular vistas and lush pine trees, the velvety green course conditions and the wildlife that you'll see everywhere. Architect William Bradley Booth designed The Ledges, and both the course and the designer won instant recognition after our opening. We like to say, in fact, that The Ledges put Brad Booth on the map in the golf world when we opened for play in 1999. That year, Golf Magazine named us the best new public golf course in New England. Since then, Golf Digest has awarded 4½ stars to The Ledges Golf Club.
