Issues after 3 years of wrapped storage

[Liv2Fish]

So I unwrapped the chitbox after 3 years of dry storage. This is a 01 206 keylargo that was used quite a bit before kids but meticulously maintained. It has seen very little use over the last 6 years and has been shrink wrapped entirely for the last 3 years. None of this stuff existed before I put it away after last use.

There are spider cracks originating from almost every transom penetration. There are hairline cracks at most 90 deg corners around the transom and rear compartment areas. There is a nasty crack at the top of the transom where it turns out at the top where the motor is mounted. WTF??

I'm assuming this is all caused by the (supposidly resing impregnated) glass wrapped plywood transom absorbing water and swelling. It's all easily fixed with a dremmel tool and new gelcoat but how did this happen?? The boat was dry inside the entire time it was wrapped.

Is this a Keylargo trait? There is a lifetime stringer and transom warranty? Do you think this qualifys as warranty?
