That was a pessimistic view on it in my opinion. Your boat is still very much competitive in the F16 class.

Vectorworks is still in business so any claims should be possible to present for them? My sympathies for being between a rock and a hard place due to business decisions out of your control.
I am not afraid to whip out the skilsaw, epoxy and glass so I would get into fixing any issues myself when/if warranty expired. Perhaps you could do something similar, or have some connections able to teach you?
