🔍 Key Concepts

• Narrow channels and fairways in crowded traffic areas • Purpose and location of auxiliary channels versus a main ship channel • How large commercial traffic typically uses the Thimble Shoal Channel approaches

💭 Think About

• Think about which channels are normally intended for deep‑draft / large commercial vessels versus smaller or local traffic when passing between Trestle "A" and "B". • Ask yourself whether there is any situation in this area where "any channel" would be acceptable, or whether traffic patterns are more strictly organized. • Consider why exam questions about a specific named channel (Thimble Shoal) often focus on keeping heavy traffic in predictable, designated routes.

✅ Before You Answer

• Verify on the chart which channels are actually marked and named near Trestle "A" and "B" and how they connect to Thimble Shoal Channel. • Check which of the options suggests an unrestricted choice ("any channel") and whether that fits with safe traffic separation in a high‑risk area. • Confirm whether both the Main Channel and South Auxiliary Channel are used for through traffic after entering Thimble Shoal, or if one is primary for that leg.
