Harley is definitely on outdrives..
Having met the owner a few times & witnessing his antics around weymouth /Portland area. I'd be confident the sinking was due to human error sadly!
There must be two Paul..
This one is definitely a 40, with outdrives. I used to walk past it to get to my boat..
As said earlier its also the same boat which hit weymouth bridge last summer & tore off its radome/aerials, damaged the arch etc etc
Such a pity, she used to be a nice boat
This is/was the boat which struck Weymouth town bridge last year around this time! (Videos of it went viral).
Before that incident, the owner also managed to fill his domestic water tank with diesel!
From your description I would throw in a cheeky offer of 4k and go from there! There's gonna be so many unknowns to overcome, admittedly if you can do all the repair works yourself you could get a cheap boat. If you've got to start paying people then the costs could rocket!
The current owner...
