RE: 2004 Cobia 184 CC specs Vs Sea Hunt
I can't offer a whole lot of suggestion, but here goes. I went out last summer on essentially the same boat (185, with 2 stroke yamaha 115). Overall, pretty nice boat. I thought it needed tabs (then again, most boats do benefit from them). To me, that price sounds pretty good. MSRP on a 2005 with F115 looks to be around $25k (although I'm sure you could get it for less).
As far as Sea Hunts go, I've heard lots of great things about them, but never been on one. It is, however, high up on my list of boats to look at next.
