🔍 Key Concepts

• Under-keel clearance (UKC) = charted depth minus draft (adjusted for tide) • Using a tide table (or graph) to find the predicted height of tide at a specific time between high and low water • Converting between feet and meters and checking which answers are realistic based on the vessel’s draft

💭 Think About

• Ask yourself: What is the vessel’s draft, and what is the charted depth at the ship’s position? How do you combine these with the height of tide at 0731? • Where is 0731 relative to the nearest high or low tide on the tide table, and how does that affect the total depth of water? • After you compute the total water depth and subtract the vessel’s draft, which answer choice is closest to your calculated under-keel clearance?

✅ Before You Answer

• Be sure you are using the correct time zone and time (0731) from the tide table given in the problem • Confirm you are using the correct charted depth (not another nearby sounding or the depth at a different point on the track) • Double-check your unit conversions (feet ↔ meters) so your under-keel clearance matches the units used in the answer choices
