The two float halves are joined together. The float half still in the frames takes care for the correct shape, while the hull half on top is out of shape between the bulkheads. Once correctly aligned at both ends and bulkhead stations, this is not a real problem. With some temporally screws the shape of the hull half on top is easy corrected to the shape of the hull half below. With some bog between and taped bulkheads in the middle, the now joined hull is strong enough to release from the frames and, while turned in a convenient position, to go inside for taping the keel and deck join. I am happy with my four electrical winches in the ceiling, with which I can lift and turn the hull on my own.
Combined hull halfs.
