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.
A sail is “cut” into several areas that have specific names. A sail is a surface in 3 dimensions.
A profile is a section of the sail along the mast.The profile of the sail changes with height but also with trim.
