What should be done when the distance to be measured exceeds the span of the dividers?

When the distance to be measured exceeds the span of the dividers, setting the dividers at a specified number of minutes to mark off the distance is the most effective solution. This technique involves adjusting the dividers to cover a specific range and using them repeatedly to measure longer distances by marking points at regular intervals. It ensures that the measurement remains accurate and allows for a methodical approach to determining the total distance.

This method also harkens back to traditional navigation techniques, making it an essential skill for boat crew members who may not always have access to electronic devices. Other approaches, such as measuring with a ruler, can prove impractical for larger distances. Estimating the distance visually lacks precision and can lead to significant errors, while relying solely on a GPS device may not always be possible in all navigation scenarios. Thus, using the dividers to mark off the distance in segments strikes a balance between accuracy, practicality, and sailoring skills.
