Funny, I've been through it and I don't see any
partical board. All seems to be plywood and everything except for under the dash is coated in fiberglass and pretty thickly too. It's about the same construction as my old Crestliner and that lasted 35 years in my family - only replaced the floor in that because it was left without a cover for a couple winters.
There's no rot, no soft spots - zero. I'm not an idiot when it comes to boats - like I said, I grew up around them and have owned them before. I know a bit about what to look for. It's a very dry climate out here - what gets wet doesn't stay wet long. Additionally any snow we get is very powdery - and I'm doubtful if any has ever gotten inside. Floors are less likely to deteriorate out here than gel coat getting chalky and seat vinyl dissolving.
If I would have suspected anything of what you describe, I would have walked away. I walked away from six or seven boats previously after looking at them for one thing or another - and none of them had Bayliner written on the side.
You're exactly the snob I was describing in my first post. Could be junk or might not. So far it's not. Two weekends full of tooling all over the place - and going out again this weekend. Runs great, gets up and goes and hasn't sunk. I'd call that a good boat. So you can go bash Bose. I'm going out on the lake with a cooler of beers, a tube and the family on my K-mart boat with the Sparkomatic stereo blasting (it may actually be one!).
