⚖️ Dinghy Mechanics

Reading time: 1 minute approximately

The objective of this chapter is to understand the main mechanisms that allow a dinghy to sail.

The mechanics of the dinghy is actually a complex science requiring significant mathematical knowledge. Important “shortcuts” will be made in order to get to the point.

In all that follows, we consider a dinghy that moves forward at a uniform speed with no change in heel/pitch/roll.
