Suitable for all fitness levels; you should be able to step on and off a small dock and stand or sit on deck for several hours.
Set off from Portland’s working waterfront on a private powerboat and chart your own course through Casco Bay. From iconic lighthouses to seal-haunted ledges, this customizable cruise is an easy, wildlife-rich way to experience Maine’s coast.
The engine’s low thrum becomes part of the harbor’s soundtrack as the dock recedes and Casco Bay opens like a bruise of deep blue. On a private powerboat out of Portland, Maine, the city’s slate-roofed skyline slips behind you and the air sharpens with salt and diesel. Seabirds wheel; a seal watches with an eye like a polished coin. For families or small groups, a two-, four- or six-hour private charter turns the famous coastline into a tailor-made circuit: lighthouses, lobster boats, and islands you can only reach by water.

Plan to be at the dock at least 10 minutes before departure so the captain can brief you and stow gear; parking is available on Front Street and Dyer Street.
Even on warm days the bay can be chilly and windy—layers keep you comfortable while moving between sun and spray.
Spray and sudden gusts are common; a dry bag protects phones and cameras when you move about the deck.
If seals or porpoises are nearby, stay quiet and let the captain approach at safe speeds to avoid disturbance.
Portland’s harbor has been a strategic maritime center since the 18th century; Portland Head Light (1791) marks an entrance once vital to commerce and defense.
Casco Bay faces challenges from stormwater runoff and marine debris; choose operators who follow no-trace practices and avoid disturbing wildlife.
Protects against bay wind and spray—useful any season but essential in spring.
