Fig. 7.—“SPAR-DECK” TYPE.
Fig. 8.—“AWNING-DECK” TYPE.
Fig. 9.—“SHADE-DECK” TYPE.
[Fig. 7] shows a “spar-decker,” which is the first of the three-deckers that we shall now mention. This was evolved for the purpose of carrying passengers between decks. It has a continuous upper deck of fairly heavy construction, the bridge deck, of course, being above the spar deck. In [Fig. 8] we have the “awning-decker,” which has a continuous deck lighter in character than the last-mentioned type, and like the latter, the sides are completely enclosed above the main deck. Because of this lightness of construction, it is not customary to add further erections above that are of any weight. Its origin was due to the desire to provide a shelter for the ships employed in carrying Oriental pilgrims. Later on this type was retained in cargo-carriers. Finally, we have the “shade-decker” as in [Fig. 9], which is provided with openings at the side for ventilation. This type is so well known to the reader from posters and photographs, that it is scarcely essential to say much. But we may remark that the lightly constructed deck fitted between the poop and forecastle is supported by round stanchions, open at the sides (as shown herewith), but sometimes closed by light plates. It is built just of sufficient strength to provide a promenade for passengers, or shelter for cattle, on the upper deck. This is still a very popular type for intermediate and large cargo steamers.
