Green stage

The chemical process of curing a resinglass hull can take days or weeks. Although the resin may appear to have set quite firmly in less than an hour, the assembly may be susceptible to permanent distortion for a period of weeks. If left unsupported during that time. it may take on a permanent change of shape. This is part of the green stage, though the greenest part is in the first hour. Moral: if you buy a freshly moulded hull, set it up true, support it well, and build in stiffen¬ing bulkheads and the like before supports are moved.
