There isn't any episode of "Star Trek" quite like "Explorers". It is at heart a character study, with excellent scenes between Sisko and Jake. A little creative license is taken with the solar sails, although that didn't stop the episode being given an award by the Space Frontier Foundation for its creativity. The inside of the solar sailing vessel is also very interesting looking and quite evocative of a Jules Verne novel.
The episode also has an excellent "B" story with Bashir facing a competitor from Starfleet Academy and features Bashir and O'Brien together singing when drunk.
