The propulsion system is a critical part of all patrol craft. There are different types of propulsion systems available for use on these craft, and selecting the “best” one for the application at hand is not to be taken lightly. You will note that I used “best” in quotes, which I’ve done to hint at the subjective nature of the decision. Propellers, waterjets, sterndrives, outboards – they are all commercial off the shelf technologies which are mature and used in different patrol craft applications.
