Mass bay Lines is a local, family-owned boat charter and public cruise company. For over 53 years the Spence family has provided affordable, safe and memorable cruises to visitors and local families. We operate six vessels - five motorboats and one sail schooner. They are available for private and public cruises. Corporate, social and NPO's have all been aboard our boats -each having the same reaction: "WOW, what a terrific way to SEA Boston!" The schooner cruise, new and one of our most popular, can come either pirate themed or knot! The Music City Queen, a motor vessel capable of carrying almost 300 guests is the Belle of the Bay, an elegant grand dame perfect for uptown events.
