We had a 5 species day ā harbor porpoises, common dolphins, Atlantic white sided dolphins, a humpback and a finback. The boat was smaller (and better) that the larger whale watches out of Boston. There were fewer people on board. So, we always had good views. The crew was great ā especially the narration. And parking was free and convenient. We happened to have fabulous weather. It was all around a perfect day. Highly recommended!
