distance between the observer and the ship decreases,
other features appear until a complete distant view is
possible. Actual first sighting of the vessel will be of
masts, kingposts, funnels, and superstructure because
the ship will be hull down. The vessel must then be
studied according to a definite plan. The most obvious
method is to start forward and work aft noting the
prominent features in sequence, as listed below. (See
figure 27.)

Hull Design
It is unlikely that the hull will be sufficiently
distinct at a distance to enable an accurate initial report
to be made. However, once the vessel is well above the
horizon, distinctive features begin to appear, such as
stems and sterns. These features can be added to your
amplifying report. By numbering the castles from
forward to aft, as in figure 28, an indication of the hull
form can be given. For example, a three-island ship is
described as having hull form l-2-3, and ships that have
no raised castles are classed as flush-decked vessels.
