so i have science homework on systems. anything can be a system , like something as simple as a toothbrush . or something as complex as the sun-earth-moon system.
what is the energy input , energy output, and the energy transfer of a SAILBOAT system ?
for example, i think the energy input would be the wind hitting the sails causing the boat to move.

energy output could be friction with the water

I think your teacher is trying to get you to see that the energy input and the energy output will be equal. Not all energy output will be in the form that the user wants it to be. In the case of a sailboat, some of the energy input is wasted on drag.
The energy transfer -- do you mean changing energy from one form to another? Kinetic energy of the wind is changed to ...

the energy input is probably the wind.
the energy transfers from the wind to the sails?
