Foul, if, in fact, they told you they were only going to honor warranties on '04 and later, you have legal recourse. They state on their site that they honor warranties from 2001 on. In any case, there are just too many illogical comments for me to just buy into this without more information. You didn't respond to my question about how these cracks appeared two days after delivery, assuming that you, as a professional, inspected the boat before you took delivery. Frankly, I, knowing that they only have a 90 day warranty on cosmetic defects, would not have waited nearly two years to start making an issue of this. It's just that we've been down this road many times before, having some disgruntled boat owner post very one-sided and slanted complaints. The majority of these turn out to be bogus when the "rest of the story" is revealed.
In that regard, I took a minute to call Dan McCarthy at Twin Vee. Guess what? The other side of the story is 180 degrees from yours. Dan said that he called you last week and stated that they intend to correct the problem but needed a little more time. He also stated that they intend to correct this relatively minor problem even though it is a result of a slightly too-thick application of gelcoat and insufficiently countersunk screws. The cracks, small as they are, are simply cosmetic and do not affect the structural integrity of the boat. Speaking of integrity, I was also told that there were some very valid reasons for terminating your relationship with them. It would seem that you jumped the gun a bit with your internet posting. Let's hope that, once the problem is corrected, you are man enough to repost that fact on all the sites that you have visited.
