Boothbay Harbor’s first whale-watching company proudly still touts itself as the best, and it’s hard to dispute the claim. Its vessel is large and fast, with both a sheltered lower deck with large plate glass windows for viewing, and a spacious upper deck where passengers are free to roam to seek out the best views. Experienced captains know just where to travel in the Gulf of Maine for the best chance for viewing humpback, fin, minke, and other whales in their natural environment, while onboard naturalists help explain the behavior of the animals when sited. On those rare days that no whales are sighted, Cap’n Fish offers a free return ticket that is good not only for another trip, but can also be used instead on several other area attractions.
