What is the model, length, and year of the boat that you have asked us to evaluate?
The hull has had a rough life.
To assess the transom integrity you need to test its rigidity by using the gear case of the outboard engine as a lever. See if you can deflect the transom.
Stress cracks often appear in areas where the gel coat resin layer has been applied too thickly. This happens typically in areas where there is a bend in the surface, which in the mold forms a recess. If the transom has any flex, it can also create stress cracks.
Minor abrasions to the hull along the chine lines are common.
What I find most interesting in the illustrations is this hull appears to have been molded in some portions with a gray gel coat finish, and then subsequently been painted to an off-white or white color. The paint appears to be flaking off. The use of a gray gel coat finish would be typical for a boat made for military use. It appears that any sort of sanding or fairing will result in a change in color to gray from white. This probably means that the entire boat will need to be repainted. At least, that is the impression gained from viewing the illustrations, particularly Fig. 3. It looks like the interior was originally a gray gel coat. The hull may also be painted, but the illustrations do not show it as well as the interior illustrations.
To know if the hull contains entrapped water is impossible from a photograph. Please see the
FAQ for more information about entrapped water.
To restore the boat to a like-new condition will require considerable work, but I would not characterize the boat as a "throw-away", unless there are further problems with the basic structure and integrity of the hull. But it will be a project.
Radial stress cracks at fastener holes are usually caused by poor workmanship when the fastener was initially installed. The gel coat layer must be relieved and made larger than the fastener in order that the process of initial threading of the fastener does not crack the gel coat.
