Question 1 of 27070

A jack-up, while level in transit at 10 feet draft, experiences a wind gust which results in a port draft of 11 feet. What is the new starboard draft?

🔍 Key Concepts

• Transverse stability and heel on a jack-up when draft increases on one side • Relationship between port and starboard drafts when the vessel was initially level • How a change in draft on one side affects the draft on the opposite side if the vessel pivots around its centerline

💭 Think About

• If the jack-up was originally level at 10 feet draft on both sides, what does an 11-foot port draft tell you about its heel? • When a vessel heels toward port, does the starboard side go deeper or become shallower in the water? Visualize a cross-section of the hull tilting. • Is the change in draft on the opposite side necessarily equal, greater, or less than the change on the heeled side for a small heel about the centerline?

✅ Before You Answer

• Confirm that initial drafts on both port and starboard were the same (10 feet). • Visualize the vessel rotating (heeling) about its centerline and how that changes immersion on each side. • Check which option reflects a shallower draft than the original 10 feet and which reflect a deeper draft; decide which matches a heel toward port.
