Centuries ago, seafarers landed on the shores of Maine from rough waters leagues beyond. We can only imagine how much of what they found took their breath away.

Today, we continue to be spoiled by the beautiful waters of Casco Bay and the views and experiences that abound here. There really is nothing like it. SeaPortland brings you straight into the heart of authentic Maine. Aboard the Elizabeth Grace, we show you the parts of Casco Bay unseen by most. We provide experiences that strike at the heart of what makes this part of the world so magical.

Join us for boat tours of previously unexplored early nineteenth-century forts. Bathe in the warm lights of a summer sunset over the water. Breathe in the ocean air while viewing Maine’s famous lighthouses. Toast local craft beverages. What could be better?

We had a great sunset sail around Casco Bay, and Sam helped make it educational and entertaining. The waters were beautiful and the sunset was gorgeous!

Our tour was amazing! We got to see three or four lights houses, enjoyed a wonderful local beverage, heard enthralling tails about the local islands and laughed with other guests. Perfect end to our day. The sunset trip was so well timed.

My second summer taking a Portland trip with friends and second trip with SeaPortland. What a wonderful experience! The boat is smaller but much more comfortable than the crowded big ferry-sized boats. The captain and mate are VERY friendly and knowledgeable and will tell you as much or as little about the various sights around Casco bay as you’d like to know. The whole bay is just gorgeous! This boat trip is a highlight of any Maine vacation.

My group of 6 (3 adults + 3 kids) took the Fort tour and loved it! The boat was cleaned, the crew knowledgeable about the local sights and helpful loading/unloading the group, and the tour of the Fort was amazing!

Incredibly informative and interesting tour of Ft Scammel! The tour is contextualized within the scope of Casco Bay and the overall history of the area. Highly recommended and very professional!

This was exactly what we were looking for in a boat tour. Our guide and captain were both knowledgeable and fun. The tour booked was a small group lighthouse tour which was close to two hours. Highly recommend!

Zach and Jonah were fantastic captain and guide! They were both very knowledgable about the history around Casco Bay. After a member of our party forgot his phone on the boat they went out of their way to return it to him. Much appreciated! I highly recommend this tour!

We loved the trip around the harbor with Mark²!Beautiful views and hospitable water; we're thankful we got to jump on a trip before the season was over. Plus the brews were a great sampling of local beer! Thanks from Texas!

We had a great time on the SeaPortland cruise. The captain was so good, excellent boat driver. First Mate Lauren was an excellent tour guide and wildlife spotter, pointing out bald eagles and seals.
