With the bulkheads all in place, the longitudinals can be slotted into place
The fore – aft position is obviously fixed by matching up to the bulkheads. The height is adjusted until the marked water line matches the marking on the bulkheads. My laser level made the whole process relatively straightforward.
Then out comes the icing bag to squeeze a line of resin into the corners made by the crossing of bulkhead and longitudinal. The resin mixing sticks have a nice radius on one end to shape the resin in the joint.
After the longitudinals have been glued in place, the transom can be screwed and glue in place. I have the shape of a boat emerging!
