190 THE SUBMARINE TORPEDO BOAT
ordinary repairs, and in addition to this she carries in
storage a supply of extra parts and fittings for each boat
of her flotilla. She also carries a considerable supply of
fuel oil for the submarines and thirty-six spare torpedoes.
Besides quarters for a complement of 131 men and ample
Type of Italian “Mother” and drydock ship for salvage and repair of
submarines
accommodations for all the crews from the submarines
there is provided a commodious and extremely well
equipped sick bay.
The testing and dry dock feature of the ship is attained
by having a cylindrical steel caison constructed within the
outer hull of ordinary ship form. The cylindrical section
has an overall length of two hundred and ten feet and a
diameter of twenty-three feet which affords sufficient space
for conveniently docking and repairing a submersible one
hundred and ninety feet long. The submarine is floated
into the dock through a movable caison fitted to the after
end of the cylindrical section. The ship at this point is
built with two extended sterns or pontoons with the caison
lock entrance between, or in other words like a catamaran.
This way of constructing the entrance to the dock permits
the forward end of the cylinder to be permanently sealed
and therefore enables the vessel to retain the ordinary bow
form. In fact she retains the ordinary ship form of con-
struction way aft to the entrance caison.
