Casco Bay Custom Charters is Portland, Maine's, most exclusive boat tour operator. We are the only private charter operator on Casco Bay that uses a vintage wooden lobster boat, and we are the only company to include a tour guide on EVERY charter. Bring your friends, family, or just that special someone and join us in viewing southern Maine's best coastal sights in the relaxed comfort that only a private charter can provide. Whether you want a 2-hour sightseeing or sunset cruise, an evening-long private dinner cruise with our onboard chef, or a half- or full-day adventure around the bay, your family or small group will get an authentic Maine experience that most people only dream of.
