🔍 Key Concepts
• Navigation Rules Rule 26 – Fishing Vessels (day shapes for vessels engaged in fishing)
• The standard day shape for a vessel engaged in fishing (nets, lines, trawls, etc.), regardless of length, when actually fishing
• The difference between shapes used for vessels at anchor, constrained by draft, and fishing/trawling
💭 Think About
• First, recall which single day shape is required for any vessel that is engaged in fishing, whether trawling or other than trawling. What is that basic “I am fishing” shape?
• Now compare that remembered shape with the four options (ball, diamond, hourglass, single cone). Which option exactly matches the standard fishing day shape shown in Rule 26 diagrams?
• Consider what the ball and diamond are normally used for. Do those shapes indicate a vessel fishing, or do they mean something else, like at anchor or constrained by draft?
✅ Before You Answer
• Verify in Rule 26 that a vessel engaged in fishing (trawling or other fishing) shows the same basic day shape to indicate it is fishing.
• Confirm which shape (ball, diamond, two cones apexes together, single cone) is specifically labeled as the fishing vessel day shape in the Rule 26 figures.
• Be sure you are choosing the shape that indicates the vessel is currently engaged in fishing, not just restricted in ability to maneuver for some other reason.
