The boat slips away from 13 Ocean Gateway and the city contracts into a watercolor of piers and rooftops. Salt air sharpens; the harbor opens and the 39-foot wooden tour boat Ruth, built in 1935, rocks with a steady, old-boat confidence as she threads between islands. Ahead, the sun lowers itself toward the horizon and the lighthouses of Casco Bay begin to outline like punctuation marks—white towers catching flame before the sky cools.

Adventure Tips
Dress in layers
Even summer evenings on the bay turn cool fast—bring a windproof jacket and warm mid-layer to stay comfortable on deck.
Bring a small cooler and picnic
Food and drink are allowed aboard; pack spill-proof containers and a towel for the occasional spray.
Arrive early to board smoothly
Plan to check in at the dock house before departure; boarding surfaces can be uneven and lines move faster when you’re on time.
Protect your camera gear
Use a strap and a weather-sealed bag; golden-hour light is stunning but sea spray is constant near the bow.
