WHY BOOK A FULL-DAY WHALE WATCH?
Eight hours lets the boat follow whale activity much farther and longer than a short cruise, with more chances for breaches, dolphins, monk seals and even rare sightings.

HOW THE CRUISE RUNS
The yacht departs the south shore, usually the calmer side in whale season. From the tuna tower the crew scans for whales, dolphins, monk seals, turtles and seabirds, and stops so you can snorkel or swim. Bring food and drinks to prepare in the full galley.
