Q

Entering from sea, how would a daymark on the port side of the channel be indicated on a chart?

🔍 Key Concepts

• IALA B lateral buoyage system used in the United States ("red right returning") • Difference between buoys and daymarks and how they are shown on charts • Chart symbols for port-hand vs starboard-hand aids when entering from seaward

💭 Think About

• First decide: entering from sea, is the port side of the channel marked by red or green lateral marks in the U.S. system? • Next, recall which geometric shape (square/can vs. triangle/nun) is associated with that color and side of the channel. • Finally, think about how fixed daymarks (not floating buoys) are drawn on the chart: what color is the symbol, and is it a square or a triangle with what letter(s)?

✅ Before You Answer

• Confirm in your mind the U.S. rule: which color is kept to starboard and which to port when returning from sea • Be clear on which shape (square vs triangle) goes with port-hand vs starboard-hand marks in IALA B. • Check that you are thinking of a daymark (fixed aid), not a buoy, and how its symbol is simplified on the chart (single letter vs two letters).
