🔍 Key Concepts

• Tide height vs. charted depth – total water depth is charted depth plus (or minus) the tidal height at that time • Vessel draft – depth under the keel is total water depth minus the ship’s draft • Time interpolation on the tide curve or tide table – estimating the tidal height at 0112 from the given data

💭 Think About

• Identify the charted depth at the vessel’s position and the ship’s draft from the problem statement or diagram, then think about how to combine them with the tide height • Determine whether the tide at 0112 is rising or falling and whether it is closer to high water or low water to estimate the tidal height • Once you have an approximate tidal height at 0112, calculate the approximate total depth of water and then subtract the draft to see which choice is most reasonable

✅ Before You Answer

• Confirm the charted depth at the location (in feet or meters) and keep units consistent • Verify the vessel’s draft and make sure you subtract it from the total water depth, not the other way around • Double-check whether the tide height at 0112 has been correctly interpolated from the tide curve or table before comparing your result to the choices
