The next step is to cut planks to fit between the marks. Belt A<br />

will not require spiling, so straight tapered planks can be<br />

made. Start at Bulkhead G and install the upper plank under<br />

the quarter deck planksheer. Use two planks, one from Bulkhead<br />

G to K, and another from K to the transom. First, lay a<br />

piece of planking material over the bulkheads. Using a pencil,<br />

mark the lengths at each of the bulkheads. Next, use a set of dividers,<br />

or a tick strip, and lift the plank widths from the marks<br />

on the bulkheads and transfer them to create each plank. Draw<br />

a line through the points and cut the planks. You should now<br />

have tapered planks. Trace these planks to obtain those needed<br />

for the other side of the hull.<br />

Install the planks you’ve just cut on the hull, butting them up<br />

against the planksheer. Where the planking does not fit flush<br />

up against the underside of the planksheer, trim the plank<br />

edges so they do fit. Glue and fasten them into place.<br />

Continue the same process for the next strake below. This time,<br />

the strake will go from the bow to the stern. Stagger the butts<br />

for this strake. Install a plank from Bulkhead F to B, B to the<br />

stem, F to J, and J to the transom. You will have four planks<br />

making up the strake from bow to stern (see figure 19). At the<br />

stern, some planks must be twisted into place. They should be<br />

steam bent if the twists are severe.<br />

FIG. 20b – Planks in Belt “C” at Stern<br />

Horn timber cheek<br />

This sharp angle diminishes<br />

rapidly forward of the rabbet<br />

as shown by dotted line<br />

Generally, no nibs<br />

are used above the<br />

design waterline<br />

Move down to the next planking strake and work as before.<br />

Stagger the planking butts, starting at Bulkhead E. Continue<br />

until this strake is complete, then complete the other strakes in<br />

Belt A.<br />

For now, let the aft ends of the planks that rest on the transom<br />

extend just beyond the transom. When you plank the transom,<br />

the transom and hull planks will meet in a miter. More on this<br />

later.<br />

Laying the Planks in Belt B: Belt B is very similar to Belt A in<br />

that it has six planking strakes about the same width. If you<br />

have not removed the temporary batten, do it now. Then you<br />

may start the planking process for Belt B. Remember to stagger<br />

the butts.<br />

At the stern, a few planks should land on the transom bevel,<br />

and the others should butt against the side of the horn timber<br />

(our center keel) and up against the horn timber cheeks.<br />

At the bow, the planks feather out at the stem rabbet rather<br />

sharply. This is fine for the model, but there is an option. Many<br />

real schooners have nibs in the planking forward (see figure<br />

20a). You can do this if you desire. This also applies to Belts C<br />

and D. See the profile detail on the plans.<br />

Laying the Planks in Belt C: Belt C is also similar to Belt A except<br />

that the planks do not taper as abruptly at the stern. At the<br />

intersection of the horn timber and the sternpost, there should<br />

be an abrupt change. One plank should flow to the horn timber.<br />

The plank below it should flow into the rabbet at the stern-<br />
