🔍 Key Concepts

• Navigation Rules Rule 26 – Fishing Vessels (International & Inland) • Difference between lights (green over white / red over white) and day shapes for fishing vessels • The standard meanings of common shapes: ball, diamond, cone(s)

💭 Think About

• First, recall what day shape a vessel engaged in fishing (trawling) must display. Is it a single shape (ball, diamond, cone) or a combination of shapes? • Look closely at options A–D and identify which one shows the same combination and orientation of cones described in Rule 26 for a vessel engaged in trawling. • Ask yourself: does the rule change the day shape based on the vessel’s length (30 meters) or just require the same fishing shape for all sizes?

✅ Before You Answer

• Verify in Rule 26 that a vessel engaged in trawling shows the same day shape as other fishing vessels, and that length (over or under 20 m) does not change that shape requirement. • Confirm from the rule that the day shape consists of two cones and pay attention to how their apexes are oriented (pointing together or apart, up or down). • Match the exact geometry shown in the illustration (ball vs diamond vs cone vs two cones) with the wording in Rule 26 before choosing your answer.
