. The encyclopaedia of sport. ranged from 3 feet in Kriemhilda, and3 feet 6 inches in Miranda to 4 feet in the The conventional centre of effort, that is, thecentre of the effect of the propulsive power ofthe wind upon the sails, must also be is arrived at by simple triangulation ap-plied first to each of the sails, and from thosevarious centres of effort the centre of effort forthe whole of the sails can be deduced. The trueeffective centre of effort and also the effectiveamount of lateral resistance, differ no doubt con-siderably from results theoretically derived ; butby means of these preliminary calculations adesigner gets a rough but fairly accurate ideaas to the dimensions, displacement, stability,and sail area possible under the rating formulato which he is confined. A designer in selecting an example need notconfine himself to a vessel of the same size asthat which he is shaping out in his brain. Abasis of comparison has been established be-tween the actual ship and her model, and equally. Fig. I represents a vessel upright, withher centre of gravity in a normal is the centre of gravity, B the centre ofbuoyancy. WL the water-line. VV thevertical line passing through the centre ofgravity. Fig. 2 represents a vessel inclined, thecentre of gravity being properly placed atG. B is the centre of buoyancy shiftedout by the inclination of the vessel. M isthe meta-centre. GZ is the couple, and itis a righting couple, as the force of buoy-ancy acting perpendicularly upwardsthrough Z rotates the vessel towards anupright position. Fig. 3 represents a vessel inclined,whose centre of gravity is improperlyplaced in reference to the centre of buoy-ancy. In this case the arm, ZG, forms anupsetting couple, as the force of buoyancy,acting perpendicularly upwards throughZ, tends to capsize the vessel. Rose of Devon. In the case, however, ofvery broad shallow-bodied yachts, the corres-ponding heights may be as much as 8 or 10 ft;et. For preliminary pu
