Biofuel- enormously expensive and can damage diesel engines.
Electric- you really think you can run a fishing boat on batteries?
Fuel cells- require the mass production of H which requires more energy than you ever get out.

Biofuel, electric, hydrogen cell technology, would be great if sails were the best option, but there are many possibilities.
