Question 1 of 27070

According to the "T-Boat" regulations, what is the name given to the permanent marks placed on each side of a vessel forward, aft, and amidships to indicate the maximum allowable draft and trim?

🔍 Key Concepts

• 46 CFR Subchapter T (Small Passenger Vessels) terminology for draft and trim markings • Difference between freeboard / load line (Plimsoll) marks and simple draft scale numbers • Purpose of permanent marks showing maximum allowable draft and trim at specific locations on the hull

💭 Think About

• Ask yourself: which term is specifically used in Subchapter T to describe the marks that show the maximum allowed draft, not just any waterline or scale? • Consider how Plimsoll marks are normally used on larger, load line–regulated vessels and whether that exact term is used in T‑Boat rules for small passenger vessels. • Think about what word would most likely be used in the regulations for marks related to how heavily the vessel can be loaded and its fore‑and‑aft attitude.

✅ Before You Answer

• Verify in 46 CFR Subchapter T that these marks are required fore, aft, and amidships on each side for certain vessels. • Check which term the regulation uses as the official name for these marks, not just a descriptive phrase like "draft" or "depth." • Confirm that the chosen option clearly relates to maximum permissible draft and trim, not vertical clearance (air draft) or generic depth readings.
