We Are Authentic Maine!

Family-Owned in Portland, Maine for 10 Years!

Welcome to Casco Bay in Portland, ME!

Our family-owned, small Maine-business Casco Bay Custom Charters began it’s journey a decade ago in June of 2014.

After restoring a classic 1969 Maine lobster boat, the MONHEGAN, we began sharing our love for boating and the sights of Casco Bay. Our first boat tours were lighthouse tours and sightseeing charters. Over the past decade our offerings have expanded to offer bottomless mimosa brunch and sunset dinner cruises, private-chef boat charters, and private island transportation.

Our fleet grew in 2018 to add a vintage passenger ferry, MARIE L, allowing us the opportunity to take larger groups for tours of the southern coastline of Maine. MARIE L is a classic vessel who has been in service in Casco Bay for nearly 70 years!

We’ve learned that businesses, like people, are at their best when they cooperate and collaborate. We love working with a large number of local partners to provide our guests with the best possible experience [learn more below].

After 10 years, we’re fortunate to say we continue to have a lot of fun with everything we do. Whether it’s a sightseeing tour of iconic Maine lighthouses, or a small wedding elopement, our crew strives for an exceptional experience tailored to your perfect day on the water.

We would love to share the beauty of Maine with you and your friends and family.
