Blue Lightning's frames are erected

BLUE LIGHTNING's frames are erected.

Blue Lightning's cedar strip hull

Her Cedar Strip hull takes shape. On the centreline you can see the slots cut for the centreboard case and the outboard motor aperture. After cleaning the interior, the cedar strip was sheathed in epoxy/glass (as was the exterior surface).

Blue Lightning's interior takes shape

The centreboard case is an integral part of the boat's structure. The inside surfaces are glassed for abrasion resistance. To the right is the aperture in the main bulkhead for the quarter berth. Aft of this are two of the sub frames that support the cockpit sole.

Blue Lightning's centreboard

The centreboard being laminated.
The top is laminated Douglas fir, the lower half is cast lead (150Kg), and the two parts are held together by stainless steel plates, through bolted and encased in epoxy resin. The entire board is then glassed over, and a half round brass band is fitted to the leading edge.

Blue Lightning's coachroof under construction

Blue Lightning's coachroof. The construction is similar to that of the hull, with the flat areas made of ply and the curved bits laminated from strips of Western Red Cedar. The entire coachroof is sheathed in epoxy/glass. Carbon reinforcement is used in the deck beams, to minimise their size.

Blue Lightning's hull after turning over

Blue Lightning's hull was fully finished before turning right way up.

Blue Lightning soon after her launch

Blue Lightning just after her launch. She floats high because the interior was not completed, and she originally carried a VERY light centreboard, with only 55kg ballast.
All surfaces were finished with a minimum of 3 coats of epoxy resin, then painted with International 708 2-can polyurethane paint/varnish.

The A Frame used for raising/lowering the rig

The simple "A" frame used to raise or lower the rig. This can be done singlehanded.
