If you call Matt you can get a definitive answer to your warranty question...the time you are spending beating around the bush is way more valuable than a $5 dollar phone call...My sister lives in your city and I talked to her on my cell ( I live 90 miles south of Matt) for 60 minutes for $26 bucks...how long would it take for Matt to give you a yes or no answer if the boat is under any kind of warranty?

Since no one else seems to have experienced anything like your problem with the Blade, it makes me wonder if any moisture got in the laminate at the cracking area and froze in your -30 degree winter weather...no boat would hold up to that...
