What determines hull speed?

Hull Speed Formula Theoretical displacement hull speed is calculated by the formula: velocity in knots = 1.35 x the square root of the waterline length in feet.

Does water depth affect boat speed?

Shallow waters decrease the boat speed because the water flowing under the boat moves quickly in shallow water, thereby creating high velocity. The main reason behind the decrease in the speed is due to the boat sinks more (or draft of a boat increases) in shallow waters than in normal (more depth) waters.

How do you know if you have shallow water?

Summary of shallow water effect on manoeuvring include:

  1. Bow wave increases.
  2. Manoeuvering becomes sluggish.
  3. The engine load increases.
  4. The ship speed over water reduces.
  5. Stopping distance and time increases.
  6. The turning circle increases to a great extent.
  7. Rolling and Pitching reduces.
  8. The ship may start to vibrate.

What is the Draught on a boat?

Draft is how shallow your boat’s hull can go in the water essentially meaning, it’s the minimum depth you can safely take your boat without hitting the bottom of the hull on the surface below the water.
