Q

If your vessel has a GM of one foot and a breadth of 50 feet, what is your vessel's estimated rolling period?

🔍 Key Concepts

• Approximate rolling period formula using beam (breadth) and GM (metacentric height) • How larger GM affects stability and speed of roll • Typical rolling periods for a beamy vessel with moderate stability

💭 Think About

• What simple formula do mariners often use to estimate rolling period from GM and beam? Try writing it down and plugging in the numbers. • Given a GM of 1 foot on a 50-foot beam vessel, would you expect a very quick, snappy roll or a slower, more comfortable roll? Which time range matches that feel? • Calculate the period using the formula, then compare your result to the closest answer choice.

✅ Before You Answer

• Be sure you are using beam (B) and GM in the correct positions in the formula (no inversions). • Confirm your calculator is in proper order of operations when taking a square root, if the formula needs it. • After computing, check if the result is in seconds, not minutes, and then match it to the nearest choice.
