Ray, (See the Cherubini Forum) I believed you solved the mystery. I have a 30G - same basic hull, with the few differences you mentioned. The "Blue Nose" page was great, and highlighted the differences, the main one of which is the extended cabin trunk (we always bang our heads in the forward cabin, after a year of owning this boat) The 30T has several additional port lights, and a port lazarette that uses the waisted interior space at the foot of the stern berth. I also noticed that the backstays are mounted slightly astern, which allows for rail seats, and possibly a larger roach on the main. But probably the most practical change was the relocation of the batteries and holding tank to the rear locker, which is spacious. Our holding tank was originally located in the head, and was moved to under the rear berth, which is a real pain, and severely limits size/capacity. The 30 T is the boat we sailed at our club, and is actually the boat we wanted to buy but ended up with a 30 G instead---got a great price, so am satisfied, as is my curiousity. Thanks for solving the mystery....
