“The jewel of any visit to Newport is the opportunity to participate in a cruise offered by Marine Discovery Tours. Fran & Don Mathews have created one of the finest combinations of cruising & learning I’ve found in my travels. Their hands-on cruise is perfect for all ages. You’ll drop crab pots (and retrieve them later in the voyage), view tiny ocean creatures under the microscope (images project on a screen so all can see), and even meet a few of them up close.”
