Make sure, first of all, that it is a boat that can transport units, and check what kinds. (Frigates cannot carry anything, Caravels only carry certain units, Galleys carry everything, etc.)

Then, if you are in a city, select the unit that you want to put on the boat (it has to be in the city too) and click the "load" button at the bottom of the screen in the unit commands section. It should look like a ramp going onto a ship. If there is more than one transport, the game will prompt you to tell you which boat to put the unit on.

If you are outside of a city, you should merely be able to move the unit onto the square occupied by the boat. The squares must be adjacent, however.
