Temporary building frames are set up on building base. They are set up at a comfortable working height so that you can reach the keel, yet still get underneath the gunwale if required

Put packing tape or polythene over frames to prevent glue sticking to them

Brace frames diagonally as required, remember these frames will be used to build two hulls

Plank from gunwale towards keel on both sides. Leave planks overlong at stem.

Strips need to be trimmed narrower at aft end for approx 1200mm (4ft). Note scrap ply pieces so that temporary fastenings can easily be removed (or use long flexible strips as shown in the drawings)

The central cuddy is made as a separate unit, in plywood for both the strip plank and hard chine versions. This is the base (upside down) and you can see the large cutout for the "pop bottom"

The right way up now and being fitted out. At the front are the three anchor lockers with the deep mast step at the cabin front and a temporary cabin roof frame fitted

Cuddy almost complete, missing the front windows, so the temporary roof frame is still in place. Note forward beambox in front of anchor lockers

A hard chine Wizard being assembled for the first time, above, decks are left off to ease access. Note essential spirit level on the aft beam

A strip cedar Wizard, again the aft decks are left off until beams have been fitted to simplify access, below. Note pivot bolt in aft beam. The beams are now ready to be glassed to the inner hull skins

Forward beam in position prior to cutting hole in hull. Note anchor locker hatch

Cut out hullskins in way of beam. Insert beam until it touches outer hullskin. Mark and cut beam to exact length

Aft beam now heavily glassed to inner hull skin

The cockpit and cuddy are initially built as two units to simplify building and reduce required space. They are now joined together as shown


Initial stages of final assembly, note the outboard bracket as part of the beam pivot bolt. The alternative is to have a small nacelle in the middle of the cockpit. A nacelle is better when motoring, an aft beam bracket better when sailing. Your choice (Note this photo shows a Sango, but Wizard is similar)
