The build commences

Finally, after a very long period of cutting out complicated pieces of plywood, it's time to start putting together something resembling a boat.  First, the bottom panel, scarfed from four pieces of ply.  The bend in the bottom panel is substantial once it's on the jig.  Hence the use of many bricks - aka "Tasmanian clamps"

Once the panel was solidly on the jig, I could start fiddling around getting the centreboard case and the associated bulkhead, together with bulkhead #1 and the stem all in place, straight and level.  Definitely starting to look boaty.
