22. Then Make the Frame, the Futtocks
Futtocks were then r aised at several places, interspersed over the leng th of the ship . These were the lower ri sing parts of the frames. For the largest part of the ship they all had the s ame curvature. At most, the builder would slightly plane his mold, the plank he used to mark off the frame parts, working from the m ain frame forward and then aft.
Witsen’s detailed description for two il lustrations of the hull may serve by way of explanation (see fi gs. 2.59 and 2.60).

(151 II 20) When the bottom and the turn of the bilge have been planked, the bilge futtocks are placed on the level marks, and a plank is laid on top of the planking of the bilge, and outside planks across on w hich one can stand; as is shown at r on the plate at X [fig. 2.61].
Then a chock is nailed to the outside of the fut- tocks, with which it stands on the bilge- planking, as in e. Then a line is drawn from the stem to the stern- post, on the center line, and pulled down with another line, attached, on the cen ter line, as in b and g, and from there the transverse symmetry of the futtocks is checked as in f: then a line with a plumb is lowered from anailforthew hole depthofthehold , asin f to h, letting it hang outside the bilge planking, in or- der to mak e the facing futtocks equal in overhang, as shown from d to e. Then to each F rame timber a Putlog is attached, as in p, besides 2 Supports under- neath it, as at n and q, to support the sca olding that will have to be raised when building up the ship on the outside, besides a Strut as at o.
