The League of Underwater Superheroes is the brainchild of  Eddie “Diver Ed” Monat. Diver Ed is a graduate of College of the Atlantic, a commercial dive and scuba instructor, a former Bar Harbor harbormaster, and a Smithsonian marine ecologist. See Diver Ed in action. 

Diver Ed is well known on Mount Desert Island for the Dive-In Theater he operates in the summer with his partner Edna “Captain Evil” Martin. Join them aboard the Starfish Enterprise for the most entertaining and memorable experience of your Maine visit. This interactive, underwater (for Diver Ed, anyway) adventure is for all ages. Check out the Dive-In Theater.
