b. Standards for Marking Floating Plant.
(1) All floating plant will be appropriately marked for easy identification with only the
authorized designation. Acceptable markings for various types of floating plant can be found in
Appendix J. Markings may be adjusted for acceptable locations based on vessel design and
arrangement as appropriate. Colors that contrast with background coloring will be used for
marks. All lettering will be Gothic block capitals and all numbers will be Arabic. Lettering may
be painted on, stenciled, inlaid, burned in, welded, attached with studs, etc., to suit. The sizing
and spacing of the lettering will preferably be as indicated in Table K-1, Table K-2, and Table K-3
in Appendix K. However, smaller size lettering may be used where the table size results in an
impractical or disproportionate arrangement. In no case, will the lettering size be reduced to less
than one half the table size, or less than four inches.
(a) Name Boards - General. Name or number of vessel, of suitable size and with at least
a one-inch margin at top, bottom and ends of board(s). Name boards will normally have blue
background with gold lettering. The material used for this purpose may be patent gold leaf letters
with a Prussian blue smalt preparation background, or appropriate modern blue and gold
reflective or illuminating paint.
(b) Letters of a color that contrasts with background coloring will universally be used on
the hull, life rings, etc.
(c) An uninterrupted appearance of the vessel identification will be obtained by
considering all interfering or projecting structural members or fittings, such as port-holes,
stanchions, rubbing stakes, fenders, etc.
(2) The Classes of Corps of Engineers floating plant are designated as follows:
Class
Determination
A
vessels under 16'-0" in length overall
1
vessels 16'-0" or over in length overall but less than 26'-0"
2
vessels 26'-0" or over in length overall but less than 40'-0"
3
vessels 40'-0" or over in length overall but less than 65'-0"
4
vessels 65'-0" or over in length overall
c. Class 3 and Class 4 Self-Propelled Plant.
(1) Name Boards. Names of vessels will be displayed on name boards located above the
weather deck on both port and starboard sides preferably abreast of, or on top of, the pilothouse
at the outboard rails. Name boards shall be wood or steel or other acceptable product for exterior
use and shall be rectangular in shape. The vertical dimension shall be twice the height of the
lettering used. The designation marking shall be as indicated in Fig. K-1, Table K-1, page K-1,
except that if the resulting name board would be disproportionately large, the lettering may be
reduced in height to not less than one-half that specified. The board should have a Prussian blue
background with gold color letters, or modern blue background with gold color letters.
