Curiosity and a desire to explore the unknown might bridge that gap. We after all are quite fascinated by whales, by the idea of living in the sea, and we even here are having a discussion about what it might be like to think having only ever existed in that environment. Whales may be similar. They know of land; they know of people in boats. I guess I am suggesting tourism as a motivator. EDIT: adding - I don't agree at all with that predator outsmarting point you made. Aquatic mammals often have quite complex techniques for hunting and evasion.
