Welcome to Capt. Bill & Sons Whale Watch. We are a well established, family owned and operated whale-watching company in Gloucester, Massachusetts, and we are now in our 47th season of whale watching! Join Us For An Experience You Will Never Forget! Sail our popular three to four hour tour to view the world’s largest mammals surfacing, feeding, and breaching in the important feeding areas of Stellwagen Bank. In summer, these waters, a National Marine Sanctuary, provide some of the BEST WHALE WATCHING opportunities in the world. Enjoy the antics of the dolphins, as they swim and jump right alongside the boat. Our unique and awe-inspiring whale watching tours offer many great photo opportunities!
