Well, let's see: Hull Warranty?
OK, all you C-Dory owners who have had a hull failure, such as delamination, severe blistering, the hull splitting in two, the cabin blowing off, the windows exploding, etc. hold up your hands and let me count...
Hmmm, yup about what I expected...
Now if you are talking about the chartplotter going black, or the radar not radiating, or the sounder not sounding, all those issue would go back to the equipment maker anyway, so you do have whatever warranty Garmin, Lowrance, Raymarine, etc. offer...
IF it is an engine problem, ditto...
If it is a wiring or plumbing problem, you are mostly on your own - though if it is less than 5 years old the selling dealer is likely to give you a break on repairs - or maybe not, it is not a perfect world...
As far as leaks or gel coat cracks, you will have to solve those on your own... Not exactly a life changing event...
I have noted that the majority of owners on this forum are a capable bunch who don't hyperventilate if they have to change out a fitting or clean some electrical connections... Those who are not, will likely become so, simply through necessity...
And lastly, though the new factory may not warranty an old hull, they are likely to give advice and moral support, which is far better than the HUNDREDS of boat builders who have just shut their doors in the past 3 years and walked away, never to be heard from again... It was on The Hull Truth (I think) that there is a listing of the known boat builders that have gone dark... It is a breath taking list...
