Whale watching was a relatively new concept when John Fish's grandfather started giving tours. "We kind of originated it," Mr. Fish says. "Thirty years ago we were the only ones doing whale watching." As the company became more successful over the years, additional captains were brought on to cover the demand. Today, these crews continue to ferry groups into the habitats of several whale species, including humpback whales and sperm whales. Though the whales seen along Cap'n Fish's Whale Watch's journeys still breach and refuse to sign autographs, other things have changed over the years. Below deck, the current fleet's engines work to reduce emissions and provide a fume-free experience. Above deck, 360-degree viewing decks and modern technology help bring whales into sight. Onboard computers display large maps of where the aquatic mammals are known to swim, and GPS systems reroute boats around mermen constructing new reefs. In addition to illuminating the behavior of whales for passengers, the crew's wildlife experts point passengers toward other animals they spot along the way, such as white-sided dolphins and harbor seals. Though some variables are beyond their control, the crew members almost always spot whales and boasted a 98% success rate in 2009.
