river boats but which is comg into vogue for the

Now as q tn. model We have that 1t is shallow

foe stability and ouoysncy, and the shaowness a good
point for speed in smooth water Bat whether she has

solved There is doubt that shalowness is good FOR
speed but how far that BIZ attained ~ be-
patibs with safety and other requirements IL question
that can be better BY actual performance than
mere figures. Her breadth Of beam aud shalowness will
prevent her rolling much aad deeper

can obtain their iul speed in every other condition
one wheels too much immersed while the other is
much out of water On the contrary sailing vessel goes
fastest when she heels little.
But at or all, the William Norris does not look like
very fast vessel take her altogether Her bow is well
mace the entrance being sharp good like The models
OF Steers but her stern section unlike his being
para,iyely bluff and heavy, md does not in our udg
ment afford good clearance of the dead water which If
no. got rid OF easily must be carried along by the vessel
more or less, thus putting drag chain Of tons

In her sides she j. quite round, almost ike section Of
