🔍 Key Concepts

• Extreme Low Water (ELW) and the Old Point Comfort tidal datum/value provided for this scenario • Under keel clearance (UKC): compare the vessel’s draft with the water depth alongside at the dock • The illustration is a deviation table for magnetic compass corrections; it does not establish tide height or UKC

💭 Think About

• From the earlier steps, what vessel draft was specified, and which tidal information should you use for the dock arrival? • How do you adjust the charted or stated depth alongside for the ELW condition before comparing it with draft?

✅ Before You Answer

• Use the stated 22-foot draft from step 1; do not substitute height of eye or a compass value. • Verify the Old Point Comfort tidal information and distinguish depth at ELW from tide height relative to a datum. • Calculate UKC as available water depth alongside minus draft, then check which choice matches.
