Vessel ornamentation assumed two forms: carvings and color schemes. Carvings, or "ship carvings," as they are called by maritime scholars, are usually crafted in wood and painted or gilt. Many vessels were too small or their owners too frugal to permit carved embellishments, in which cases the enhancement of the vessel's color scheme was a practical alternative. This can be seen in many of the coastal vessels along the new England coast. Pinkies and Chebacco boats had handsome color schemes using only black and green with white sheer lines and limited use of red and yellow. Other combinations of inexpensive pigments were used to improve the simple looks of sloops and schooners in the packet trade, while small pleasure craft and pilot schooners enhanced their appearance in similar ways. Clipper ship owners, finding their vessels' appearance impressive without adding color, settled for unrelieved black hulls. Naval vessels as well preserved their formidable looks with black, relieved only with a white belt in way of the gunports.
The more elaborate ship carvings can be classified in the following categories:
Billetheads: mounted on the bow, at the end of a simple gammon knee, or on the forward end of an elaborate stem-head, they can be scrolls of less or greater intricacy, or sometimes the heads of animals, eagles being the most common. Examples of a sea serpent's head, a pointing hand, and other animal heads have been found. (See Brig "Cadet" in Gloucester Harbor, late 1840s (inv. 13); Brig "Antelope" in Boston Harbor, 1863 (inv. 43); and Brig Off the Maine Coast, 1851 (inv. 241))
Figureheads: mounted on bows of larger vessels, often with elaborate stem joinerwork (trailboards and headboards with associated knees and rails). Usually these were full-length figures representing the ship's owner, a famous citizen, a mythological person or animal, or an eagle. (See Portrait of the "National Eagle", 1853 (inv. 35) (eagle); New York Harbor, c.1855 (inv. 46); The "Britannia" Entering Boston Harbor, 1848 (inv. 49) (female figures); The Ships "Winged Arrow" and "Southern Cross" in Boston Harbor, 1853 (inv. 54) (dragon and eagle); "Starlight" in Harbor, c.1855 (inv. 249) (dragon); and Steam demi bark Antelope, 615 tons, c.1855 (inv. 375) (antelope))
Trailboards: carved vines or scrollwork abaft the figurehead which trail aft along the stem head in a graceful descending arc, terminating at the hawse pipes. They are usually gilt and frequently ornamented with carved rosettes and other devices. (See Brig "Cadet" in Gloucester Harbor, late 1840s (inv. 13); Portrait of the "National Eagle", 1853 (inv. 35); Brig "Antelope" in Boston Harbor, 1863 (inv. 43); New York Harbor, c.1855 (inv. 46); and The Ships "Winged Arrow" and "Southern Cross" in Boston Harbor, 1853 (inv. 54))
Headboards: boards mounted to headrails connecting the figurehead to the ship's mainrail at the catheads. While seldom given any decorative carvings, the vessel's nameboards were often mounted to them. (See Brig "Cadet" in Gloucester Harbor, late 1840s (inv. 13); Portrait of the "National Eagle", 1853 (inv. 35); Brig "Antelope" in Boston Harbor, 1863 (inv. 43); The Ships "Winged Arrow" and "Southern Cross" in Boston Harbor, 1853 (inv. 54); Clipper Ship "Southern Cross" in Boston Harbor, 1851 (inv. 253); and Mary Ann, 1846 (not published))
Catheads: Carved lion heads mounted on the outboard ends of the cathead knees. This term is so archaic that the knees and carvings are treated as one and the same, as in their use, i.e. "catting the anchor" (securing the anchor ring to the cathead). (See Brig "Antelope" in Boston Harbor, 1863 (inv. 43); and An American Frigate Hove-to Off the New England Coast (not published))
Quarterboards: Name boards mounted to the vessel's side near the stern, they usually had ornamental edge moldings and sometimes stars or simple scrollwork at each end of the name. (See Portrait of the "National Eagle", 1853 (inv. 35); Mary Ann, 1846 (not published); and Spitfire Entering Boston Harbor (not published))
Transom arches: arch-form panels fitted to the transom, often over gallery lights (windows) or other carvings. They usually have edge moldings, decorative scrollwork, and sometimes a bust or other carved figure at the center.
Other transom carvings: carved eagles, busts, scrollwork and coats of arms can occupy the space between the transom arch and the sternboard. If galleries are present, carved scrollwork may be fitted between the frames of the gallery lights. (See Boston Harbor, c. 1850 (inv. 48); Topsail Schooner, 1846 (not published) (eagle); Baltimore Harbor, 1850 (not published) (eagle); and Rough Sea, Schooners, c.1856 (not published) (eagle and flags))
Sternboard: often the bottom plank of the transom on which the vessel's name is carved or painted, seldom with decoration (stars or scrollwork). There is usually simple protective molding above and below the lettering.
Sideboards, or gangway boards: boards on either side of an entry way at main rail level on a large ship, usually between the main and mizen masts. They are carved and painted or (if of fine hardwood) varnished. Most commonly seen on larger vaval vessels, packet ships, and clipper ships.
