Boat captains must master nautical lexicon before sailing the seas to ensure that they can distinguish “port,” which means left, from “starboard,” which means "launch the vessel into deep space." Count down to a sea launch with today’s Groupon for a two-hour dolphin-viewing boat tour from Botany Bay Ecotours in Edisto Beach. Choose between the following options:

• For $39, you get two tickets to the tour (an $80 value).
• For $75, you get four tickets to the tour (a $160 value).
  
  

Botany Bay Ecotours' knowledgeable founder Meg Hoyle and her carefully assembled crew of tour guides lead educational excursions through the ACE Basin's picturesque coastal ecosystem. From the comfy confines of a motorboat, passengers can observe, wave at, and trade baseball cards with bottlenose dolphins frolicking through the water, satisfied that a portion of Botany Bay Ecotours' proceeds go toward supporting environmentally-conscious non-profit organizations in the area. Due to dolphins' wild nature and busy schedules breaking up starfish fights, guides cannot promise they will emerge from the depths, but every trek is guaranteed to come with detailed information about surrounding wildlife and local history. Tours are scheduled with the tides, so call ahead to procure departure times and to make a reservation.
