WHAT IS A TUNA TOWER?
It is a tall lookout platform on sportfishing yachts. From that height it is much easier to spot spouts, dolphins and turtles, which helps on a whale watch.

HOW THE CRUISE RUNS
The yacht departs the south shore, where sea conditions are usually calmer in whale season. The crew looks for whales, dolphins, monk seals, turtles and seabirds, then stops so you can snorkel, skin dive or swim. You can bring food and drinks to prepare in the galley.
