Beautiful boats, yes. But how do they move? What are the best engines and how do they differ? Better outboard and inboard? Here are seven chapters, seven propulsion systems, all of which you can find aboard recreational boats. What do outboards look like and how do they differ from inboards inline and sterndrives? And again, how do IPS, PODs, surface drives and waterjets work?
Here is Episode #4 of our “I EXPLAIN THE BOAT” videopodcast, produced in collaboration with Suzuki Marine Italia. In the studio, as usual, Luca Sordelli and Stefano Monfroni.
In this first installment devoted to propulsion systems we make an initial descriptive overview to understand their basic characteristics, in the next two we will delve into the most common types on recreational boats: outboard, inboard, shaftlines and IPS.

The model was designed according to the criteriaof the Executive Sport Vessel (ESV), an approach developed by the Tuscan
What if the boat really could moor itself? We tested the new Simrad AutoCaptain and can confirm that it’s (almost) a reality. Thanks to six cameras and onboard intelligence powered by cutting-edge electronics, maneuvers are practically automatic. You can navigate from point A to point B without touching the helm or even moving the throttles.
