Velocity Made Good (VMG) Formula
The following two example problems outline the steps and information needed to calculate the Velocity Made Good (VMG).
VMG = BS * cos(TWA)
Variables:
- WMG is the Velocity Made Good (VMG) (knots)
- BS is the boat speed (knots)
- TWA is the true wind angle (TWA)
To calculate velocity made good, multiply the boat speed by the cosine of the true wind angle.
How to Calculate Velocity Made Good (VMG)?
The following steps outline how to calculate the Velocity Made Good (VMG).
- First, determine the boat speed (knots).
- Next, determine the true wind angle (TWA).
- Next, gather the formula from above = VMG = BS * cos(TWA).
- Finally, calculate the Velocity Made Good (VMG).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
boat speed (knots) = 5
true wind angle (TWA) = 30
VMG = BS * cos(TWA) = ?
