PHS....since the GW hulls are made one at a time by hand, to have an across the board defect with voids like (Toyota's runaway gas pedal) is very uncommon. A bow flex issue for a model year would most likely be due to an engineering faux pas :?: and can be factual (but that is unknown to me) at this time. The hull would have had to be designed with a thinner than required thickness or lack of structure to flex like that. That is very different from actual voids in the laminate, which you will have on a hand laid hull as the void is caused by the glass laminator either going too quickly or not rolling/pressing out the air with his glass roller.....the two issues in most cases would not be linked unless GW had a crew of really poor glass laminators (craftsmen) working for them for 2 full seasons and caused the issue. My 1988 hull has small voids throughout, ( found this out during a stringer replacement) but is still pretty darn stiff and shows no cracks whatsoever anywhere in the hull after 20+ years. Do you know if this is a cored boat, ie, structural foam core vs solid glass?
I'm not sure what a surveyor can show you unless he can do an X-ray of the hull or see cracks in the actual gel coat outside the hull....you cannot see these small voids with a moisture meter and you cannot see them without grinding down the glass laminate under the fuel tanks or any other part of the hull.....not sure what your guy can tell you from an inspection otherwise...it would be a guess at best without tearing the boat apart. The tell tail signs would be cracks at all major joints both topside and underneath, if its visible, ie after blasting off the bottom paint.
Please let us know what you find out.....this is a major development for GW if it were true.
