    42. Lay Down the Waterway
The waterway could be fastened with bolts laterally, going straight through the ship’s side and sometime through the wales. Such bolts were more th an a yard long! This component of course strengthened the hull considerably.
43. Then add a ceiling plank or two.
(76 II 19) 24. About the Ceiling on the Waterway, and others. 1.Theceilingonthewaterwaybethick31⁄2 inches,broad
15 inches.
2. The ceiling on that one, thick 3 inches and 2 1⁄2 inches,
broad 16 inches.
43. Then Add a Ceiling Plank or Two
On the w aterway, against the f aired frames, a c ouple of spirketings were added, considerably adding to the inter- connection between the futtocks and the top timbers. Wit- sen apparently knew of no methods for sealing the seam between waterway and ceilings other than with caulking. According to l ater sources, the w aterways were sh aped
with a raised horizontal edge against the frames, raising the seam to be caulked above deck level.
44. Fit the Beams of the Upper Deck, and make the Gun Room.
(76 II 39) Their number is according to the strength the ship is to have and the number of guns she will carry: upper beams are ligh ter then lower beams, to each end of the beams a hanging knee is tted.
18. About the beams of the upper deck.
1. For the thickness of the beams of the upper deck, 2⁄3 of the thickness of the stem.
2. For the camber 5⁄6 parts.

3. For the breadth ⁄3 parts of the same.
    (76 II 29) 26. About the upper deck beams and knees. 1. The upper deck beams, thick 8 inches, broad 9
inches.
2. Have a camber of 13 inches. F orward they lie
5feet,91⁄2 incheshigh,inthemiddle6feet2 1⁄2 inches high, aft 6 feet 6 inches high. The aftermost upper deck beam lies 2 feet 4 inches away from the for wardmost beam of the gun room.
(77 I 1 3) The beams lie 3 feet 9 inches from one another.
