Not illustrated. 1898 edition. Excerpt: ... position will depend upon the changes that take place in the relative positions of these centres as the pontoon rolls to an inclined position such as that sketched in Fig. 38a. The red paint line having swung into the inclined position ACD, the point Bl will have moved away from that line, and will have described upon the bulkhead a part of the "curve of buoyancy," which is simply the path traced by the centre of buoyancy in its successive positions. The new segmental area LSi will have exactly the same shape as the original area LDS; the distance CBi will be the same as before; and a vertical drawn through B, at right angles to the chord LtSi will again pass through the centre of the circle C. Hence, in this cylindrical form of vessel, the point C becomes a virtual point of suspension, and is a true "metacentre;" and the stability of the pontoon depends wholly on the question whether, in Fig. 38, the point G is below or above G. If it is below the metacentre G, any rolling of the vessel to the right or to the left will give rise to a righting moment whose value will be W X CG sin 9, and the pontoon will return to the upright position; but if G is above C, the vessel must turn over keel uppermost. In each of the cases described in Arts. 44,45, and 46, stabilitywas only to be attained by placing G below B. Here that is not necessary, but stability depends upon the placing of G below a new centre, or "metacentre" 0, which coincides, in this particular form/with the centre of the cylinder. As compared with other and more usual forms, the cylindrical pontoon and the cigar ship possess the following distinctive properties: --The curve of buoyancy is obviously the arc of a circle which might be continued all round the...
