What is the definition of transverse metacenter?
A. The distance between the actual center of gravity and the maximum center of gravity that will still
allow a positive stability.
B. The point to which G may rise and still permit the vessel to possess positive stability.
C. The sum of the center of buoyancy and the center of gravity.
D. The transverse shift of the center of buoyancy as a vessel rolls.

ReplyDeleteYes, B is the best answer.
ReplyDeletePlease keep in mind this applies to small angles of transverse inclination say no more than 5 to 8 degrees. As B moved transversely it travels in the path of an arc for a wall sided vessel. The center of the arc is located at M where B is acting upward through M, the Metacenter. The radius of this arc is BM, the Metacentric Radius. My favorite illustration is Fig. 16-2, on page 46, of the 4th Edition of "Stability and Trim for the Ship's Officer".
