This is a good place to describe the placement of the chainplates tho it is better to delay their installation until just before you begin rigging. As the shrouds fan down from the masthead, each forms a slightly different angle with the channel, Fig. 20A. Therefore the point at which the chainplate attaches to the hull should be in a true line, masthead thru the channel notch to the hull. Temporarily set a dowl in the mast hole, swing a string from masthead height thru the notch and thence to hull, marking with pencil point. (Fig. 20B).



may be made from annealed iron wire of appropriate thickness. The loop form is more authentic, but for smaller (1/8" scale and under), the single wire with deadeye strop (or strap) at one end and eye at the lower end is satisfactory, Fig. 18. Note that the deadeye strop is a loop containing the eye, comes together, passes over the channel and gives an eye to the lower chainplate.


are easily placed. Note that they contain sheaves by which the anchor was hoisted, Fig. 21.

A word may be said here of the topside planking and bottom planking generally. On each side of the keel the planking was thick and then thinned down a little along the bottom and turn of bilge.

From the turn of bilge upwards the planking thickness gradually increased to a maximum about the waterline, which was the widest part of the beam. From here upwards to the top of the bulwark the planking tapered down again. In the later day wooden sailing ships this tapering of thickness was done gradually so that the external appearance was quite smooth except for thin mouldings. Fig. 22. Before this development the thick planking or

Main wales

at the waterline terminated in a distinct ledge on to the thinner topside planking, and sometimes another narrower ledge to the bulwark planking which was the thinnest on the hull. Profile plans of this type of ship will show a single thick line near the waterline and date roughly between the late 18th to mid 19th centuries. Fig. 23, line X.

Large warships from about 1720 onwards to the early 19th century usually had a distinct wide band of main wales with a step top and bottom, and two or three additional topside wales between here and the bulwark. This would show on plans as two parallel lines. Fig. 24.
