That boat isn't solid most likely. With the debris and sun fading the fact it was stripped and de rigged says that it had a bit wrong with it and was 'disposed of'. That shows pretty obvious neglect but it did have some nice stuff at one point. Sea Ox was a Grady White copy and are decent boats, but I would not spend more than $1,000 on that, and I put $1k into reasoning because that motor bracket would cost $1k to replace
See the thing with boat angel or other donation center is, you can take a boat that is junk, and might not even have title to, and 'donate' it, and claim it on taxes, but you can only claim so much.. That donation center will sell it for whatever they can get, regardless of it's worth or actual condition.
