When it comes to boating, one of the most important things to know is how to calculate the length of your boat. This formula, known as the 34 Rule, can help you do just that.
To use the 34 Rule, simply take the length of your boat in feet and multiply it by 34. Then, take the square root of that number. The result will be the length of your boat in nautical miles.
So, for example, let's say you have a 30-foot long boat. Using the 34 Rule, you would first multiply 30 by 34 to get 1,020. Then, you would take the square root of 1,020 to get 32. That means that your 30-foot long boat is 32 nautical miles long.
Of course, this formula is only an estimate and should not be used for navigation purposes. But it's a good way to get a general idea of how long your boat is in nautical miles.
