Boat Speed Formula
The following equation can be used to calculate the boat speed.
S = 10.34*(WLS/WLM)-10.34
- Where S is the boat speed in knots
- WLM is the waterline length when moving (feet)
- WLS is the waterline length when stopped (feet)
To calculate boat speed, divide the waterline length when stopped by that when moving, multiply by 10.34, then subtract 10.34.
Boat Speed Definition
A boat’s speed is the velocity at which a boat is traveling based on its waterline while moving and stopping.
FAQ
What factors affect a boat’s speed?Several factors can affect a boat’s speed, including its hull design, weight, water and weather conditions, and the power of its engine or sails.
How does the drag coefficient impact boat speed?The drag coefficient measures the resistance of an object in a fluid environment, like water. A lower drag coefficient means less resistance and potentially higher speeds for boats.
Why is understanding buoyancy important for boat speed?Buoyancy affects how much of the boat is submerged in water. The right balance can reduce drag and improve speed, while poor buoyancy can increase resistance and slow the boat down.
