The average draft of a typical production coastal cruising sailboat is about 3 to 4 feet. Some vessels, such as fin keel racing boats, can have much deeper drafts regardless of overall length.
How do you calculate draft on a 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.

How far out is considered offshore?
Offshore Fishing
Offshore journeys or deep sea fishing, on the other hand, commonly need a dedication of 12 to 72 hours to take you anywhere from 30 to 130 miles far from the shore. This type of water warrants bigger game fishing watercrafts furnished with larger fishing equipment sonar.
Boat Length
The most common offshore boats are usually between 30 to 40 feet, which is perfect for long trips and most weather conditions. Anything less than 30 feet will not handle weather and waves as well, but they still make for great boats if you pay attention to the weather.
A small inflatable boat can travel out 1 to 2 miles, a 20-foot center console can handle 5 to 10 miles offshore, and a cruiser can travel hundreds of miles.
