jusyt saw this thread. Heres something for the mix. Rob's boat is actually 25 3/4' on the inside of the stringers. It was also originally a jet boat though. One of just a handfull i guess.

Yes, I dont think there were too many jet packs compared to the I/Os on these 20's. I have only seen a few of them.. Donzi did some stuff like that too back in the day on the classics. Most of the stuff was always I/O, but on occassion you would see a jet, V-drive or an OB.
