Wow. what a saga. We're not power-boaters, but we've always thought the Rangers are cute, neat layout, and would be fun for a summer adventure like the Trent-Severn or Rideau
canal systems. They're always popular at the boat shows.
Was there not an out-of-water
inspection as part of your
survey?
Just my non-legal and unschooled opinion:
Don't waste a second lamenting the lack of proactive response from the dealer or the manufacturer, or feelings about being "part of the family". Job #1 is to establish the fact that the boat was damaged before you officially owned her. Be certain about this: get solid confirmation that the boat was handled and blocked carefully and correctly while officially yours.
Once this is established and provable, then go back to the dealer with this proof, and demand either proper repair or 100% refund plus expenses. Period.
I don't believe for two seconds that the original owners got out of that boat, after such a short period, after investing in a
marine railway... out of boredom. I'd bet that either the dealership quietly took it back to settle a claim from the original owner... or the original owner, having discovered or caused the damage, has quietly walked away from it.
You have a
legal problem right now, not a
fiberglass problem. A different specialist is recommended. From a repair perspective, if the damage is isolated to the area right around the visible cracks, I believe that it could be successfully repaired from the outside, but I myself would still expose as much as possible inside as well, in case there's cracks that would admit bilgewater into the
core. Interior flooding certainly suggests this. I'm guessing this will possibly be a (Canadian) 5-figure repair cost, if done by a good independent shop.
