Well, I at least got an estimate on the repairs - most of it is parts (IMCO SC). The hull held up just fine (still need to check stringers and bulkhead (if possible) when motor is removed) - a testament to the structural integrety of the Sunsation. An accident reconstruction "specialist" spent the better part of a day last week, going over the boat. He was surprised and impressed at how well the hull held up. He found no indications of anything "wrong" with the hull.
I will not be back in the water this year. At this time I am prohibited from making any mods to the boat, until I get the "OK" from the insurance company - no doubt they do not want to pay the liability (like any insurance company), and they are looking at it from every angle (e.g. mechanical failure, for instance). When it's back together, it goes up for sale. For now, I just sit and pay $600/month, unable to use her.
