4. The wing transom.
(73 II 23) In the gure No. 20 [fig. 2.16], a is the wing transom, b are the transoms, c the broekstuk [only the top of the broekstuk is visible in this sketch; cf. fig. 2.33], which joins the lower ends of the fashion pieces: d is the fashion piece, e the chocks of the gunports in the tuck.
(66 II 40) Of the Wing transom.
7. In order to obtain the length of the wing tran-
som, one takes 2⁄3 of the width of the ship.
(68 II 13) The length of the wing transom, equals the breadth of the bottom.
. ..
(66 II 44) 2. For the thickness, breadth and the curve, take as many inches as the wing transom is broad in feet.
. ..
Or: (68 I 36) The wing transom is also arranged in thickness, breadth and cur ve, as the inside of the sternpost.

The Wing transom is radial, outward.

The Wing Transom sti ens the fashion pieces, and thus holds together the entire ship.

(147 I 17) Next follows the Model of the Wing Transom as seen on the Plate at letter E [fig. 2.18].
a Is the upper side, b the back, e the inside face, f the underside, at the back it is made with a hollow , underneath which a rabbet, in which the planks of the Tuck are made fast; at d is the rabbet, c is the hollow, and when made thus, the back is laid at the inside of the Sternpost, close to the upper end, and fastened with a dovetail. I t has to be level , on the inside as on the upper side, on w hich the Fashion pieces are set, which ends are held on the sternpost. The lower side should come level with the rabbet, and the sternpost

does not protrude above the wing transom. When this wing transom is made, the camber is made after the length it has, and also the breadth and the thickness, as is to every ten feet of length eigh t inches to the camber,andtothebreadth everyfootoflengthone inch of breadth, and the thickness slightly less.

(73 II 6) 4. Of the Wing transom.
1. The wing transom be 19 feet 6 inches long, thick 1 foot 21⁄2 inches, broad 1 foot 31⁄2 inches.
2. The wing transom has a cur ve of 1 foot 2 inches, the rabbet long 31⁄2 inches, deep 3 inches.
3. The hollow above the rabbet long 3 inches, deep 1⁄2 inch. All that it is more, remains square, it’ s joined half into the sternpost, and secured with a dovetail, two bolts are struck through, which also go through the sternpost but for one inch.
