"radio shack" That brings back a lot of memories.

I have been absent for awhile. Great the Radio Shack name came up. I was on the the coast of Alabama last week and I needed a 25 ft cat 5 cable and I saw a Radio Shack and pulled in. I asked the owner that I thought all the stores closed up and the company went into bankruptcy. He went on to tell me only the "Franchisee" stores were still open and all company stores had closed. Anyway a piece of Radio Shack trivia.

Just from the ballast set up I would expect the G to be louder. 1400# of lead. Boat was probably turning 3700-3900 rpms vs a underweighted Ri. I have never been in a Ri without the pnp doesn’t seem like a common set up. The 550 motor boats are definitely quieter but most run the 450 Ho motor that is in no way whisper quiet when weighted with pnp and extra lead like the majority are.

could be a factor.
the more i think about it, the more i wonder wonder how the giant walk thru impacts noise? Does the increased exposed fiberglass result in less sound deadening than a fully padded or sea dek'd design? What are the engine dividers made of? Do they isolate noise from the rear compartments or do they turn into echo chambers? Are the rear compartments isolated from the port and stern side under seat storage (they are not on my 230)? Probably lots of factors at play here.

I have toyed around with the idea of applying sound deadening to the inside of my engine hatch to see how much it impacts noise transmitted to the cabin.

I didn't read the whole thread, but, has anyone discussed the "grid" stringers in the G's (no foam) vs the foam stringers in the Centurions? I would think that would have a LOT to do with dampening the sound levels in both boats.
