- BA conical shape, apex downward; vessels under 12 meters are exempt✓ correct
- CA conical shape, apex upward; vessels under 7 meters are exempt
- DA diamond shape; vessels under 20 meters are exempt
Why B is correct
33 CFR §83.25(e) requires a vessel proceeding under sail when also propelled by machinery to exhibit a conical shape, apex downward, forward where it can best be seen. A vessel of less than 12 meters in length is not required to exhibit this shape, but may do so.
