- - Very true in and of itself but with a major asterisk attached - The quality of the repair and the knowledge & skill of the "glass man" is critical to making the statement being true. For instance, with brick or concrete block buildings, the composition of the mortar and techniques of laying up the brick/block makes the difference between a "3 piggies proper brick hut and a straw-quality hut."
- - With FRG, there is an additional requirement to know how the various glass fiber matt, roving, or fabmat orientation reacts to stress imposed by standing rigging
and other stresses placed on the hull
. Knowledge of resins and resin to glass ratios can make the difference between a better than new repair and a repair that will break away/separate from the original hull
during the first storm as sea.
- - I have watched the repairs
made at yards in the Caribbean
and even in some yards in the USA and shake my head
as I know that repair is destined for failure and loss of the vessel. The workers are hired off the street and have no interest in or knowledge of how to do the reconstruction correctly. And unfortunately after the repair is finished and the boat is painted, there is no way to know if the job was done properly or "slap-dash." The owners are normally in a hurry to get rid of the boat and recover whatever money
they can get.
- - So unless you really know the history
of a repaired FRG boat it can be very risky to take such a boat out of sight of land. But just like ferro-cement boats knowing the history and how the boat was put or put back together can make all the difference between a fabulous good deal and a disaster waiting to happen.
