Boat rides in Ocean City, MD?

Was wondering if anyone had rode the assateague adventure boat ride.. my family and i are going on vacation to Ocean City, MD in a few months and are looking to do some new things we've never done there before.. what all do you do on the boat, is it worth the money? And if anyone else has any good family activites to do there that would be helpful.. (does anyone know where theres like a big shark mouth statue that kids can sit in the mouth?) thanks for you time
