How do I find the draft of my boat?
Boat Draft Formula
To calculate a boat draft, divide the weight by the density, then divide this result by the result of the length divided by the width, then finally, multiply by 3. This draft also does not include motors of rutters. Those should be added to the total draft.
What is the draft of a boat called?
A boat’s draft is simply the distance between the waterline and the deepest point of the boat.
