Which mooring type allows up to 64 kt wind with 2 kt broadside current or less?

• A. MST I
• B. MST II
• C. MST IIA
• D. MST III

Answer: (B)

Mooring types define what environmental loads the mooring system is designed to withstand. The key factor here is matching wind and current conditions to the rating of the mooring arrangement. For a scenario with very strong winds (up to 64 knots) and only a small broadside current (2 knots or less), the rating that accommodates that combination is MST II. This type is built to handle near-gale to gale conditions with minimal cross-current, ensuring the vessel remains securely moored without overloading the lines or fittings. Other mooring types are set for lighter or different load profiles, so they wouldn’t be the best fit for these specific conditions.
