Most photos in this section were supplied by Gary Wallis, who built his Cape henry 21 from a kit supplied by Jordan Boats in UK. Where photos are supplied by other builders, their names are alongside the relevant photos. Thanks to all builders for your contributions.

Some photos are of Cape Cutter 19 plywood projects, with identical detailing.

	Sergio Vianna is building a plywood Cape Cutter 19 in Brazil. Here he is holding the backbone and standing within the building stocks.
	Sergio Vianna's Cape Cutter 19. Here he is laminating the curved plywood transom and its doublers over a temporary former.
	Yuri Pikulyk is building his Cape Henry 21 in Moscow, Russia. Here he has the bulkheads set up and the centreplate case fitted. He has also fitted the locker fronts between the 3rd and 4th bulkheads. This is part of the interior joinery and can be done at this stage or later after turning the hull upright.
	This series of photos was supplied by Gary Wallis, who built his Cape henry 21 from a kit supplied by Jordan Boats in UK. Thanks Gary, for your photos. The bulkheads have been set up and the stringers fitted. Some of the detail of the building stocks can be seen in the photos. This is the mast bulkhead, looking aft. You can see the mast support post and the laminated deck beam that links the two halves of the bulkhead at deck level.
	Bulkheads set up on building stocks and diagonally braced to keep them plumb and level. The backbone interlocks with the bulkheads, helping to keep the structure rigid during assembly. The stringers have been joined to the stem and fitted into the bulkhead slots.
	Transom set up on building stocks. The transom and its doublers have been laminated over a curved former to set the transom rdius.
	In this photo the transom doublers are clearly visible, as well as the framing that is holding it to the correct angle and position. The stringers are slotted into the transom doublers but do not pass through the transom, which covers the end grain of the timber.
	Aft view of hull skeleton. The sheer clamp has not yet been fitted, allowing easier access to the interior of the hull.
	Forward bulkheads, with backbone slotted in. The bottom panel (topmost in this upside-down photo) has a stringer in the middle of the panel from the stem to the mast bulkhead. All other stringers are at the chines, helping with the shaping and fastening of these joints of the hull skin. The bottom panel on the other side has already been fitted in this photo. It is important that the forward sheet of this bottom panel is done with okoume plywood. If done with meranti, mahogany or fir plywood, it will be too stiff to accept the twist that this panel needs, so construction problems will be the result.
