The first thing to remember when talking about marine batteries -- batteries for your yacht or boat -- is that there are two main types of such batteries, serving two separate purposes. The first one, called "cranking batteries," is the one used for starting the main engine, while the second one, "deep cycle," are meant for trolling motors.
Here's where the main differences lie. Cranking batteries, the ones intended for the main engine, contain a number of thin lead plates giving better bursts of energy, which is needed for a quick start. Deep-cycle batteries, used for trolling motors, come with fewer but thicker plates, whose purpose is providing better power-output for a longer period. The thicker plates also do a better job in withstanding higher temperatures, which the motor will encounter when heavy current is drawn down for an extended run-time.
