A lot ;)
 

It'd take some time to put a # on it.
$150. per is pretty good money for labor too. I do that work down here for $75. per on the very few jobs I accept.
What I tell people is that you have to do it because you want that boat not because it makes sense to anyone else or is a wise investment as we all know it's not.
I look at the time/$$ I have in my ancient Sonic and compare that to what it would cost to replace it w/something new/newer that does everything it does and it always ends up being $30K+ used and $100K+ new. (we just spent 5 days/nights on ours in the Keys)
I probably have $10 - $15K in mine including motors.
If you could get that hull for a couple $K and do a hull up restoration and have maybe $10 - $15K in it, IMO you'd have something. Whats a virgin 28' Pantera worth? Can you even find one?
If it were closer and I had the space......., I'd look seriously at it.

Yep...that one is only worth it if you can get it really cheap....and you can do all the work yourself. I did mine myself, and know what I have now, altho I never would have paid somebody to do my boat for me. Not worth the money. 2cts

Kinda like.....
 

the story I read about a shop that specializes in restoring old Boston Whalers. Why pay twice as much to restore a 17' Montauk than what you can buy a E.C. condition version that's turn key?
Has to mean something to and be worth it to the owner.

As an investment you almost always lose money.
