CHAPTER III. 
CARGO CARRIERS. 
CLASSIFICATION OF VESSELS. 
VESSELS which are engaged in the carrying of commercial 
cargoes may be classified as follows :— 
I. Transatlantic Passenger Liners, built mainly for 
speed and for the accommodation of passengers and mails ; 
they have usually a small amount of hold space for cargo. 
The s.s. Olympic, for instance, with a displacement of 
52,310 tons, carries 2,500 passengers and only 3,000 tons 
of cargo. The s.s. Majestic, of 64,000 tons displacement, 
carries a like amount of cargo. 
2. Intermediate vessels, in which the proportion of 
space assigned to cargo is much greater and the passenger 
accommodation from the primary, gradually becomes a 
distinctly subordinate, consideration. The s.s. Adriatic, 
one of the largest of this class, of 42,000 tons displacement, 
can accommodate 20,000 tons of deadweight cargo and 
fuel, in addition to the full complement of passengers and 
crew. The s.s. Aquitania, of 50,000 tons displacement, is 
capable of carrving 14,000 tons deadweight of cargo and 
fuel. 
3. Cargo vessels proper, that is, vessels devoted en- 
arely to cargo carrying. A large proportion of these come 
ander the designation of “ Tramps,” i.e., vessels which have 
no particular port or route, but which proceed from place 
to place, picking up freight as occasion offers, and available 
for charter to any quarter of the globe. Speaking generally, 
such vessels have deadweight tonnages up to 12.000 tons
