Given your out line. lots of room, fuel efficient, under $200k , room and your doing the loop I would go for the tug in 27sc. i have been on all the boats you mentioned and that would be my choice. Is the best laid out of the boats mentioned. It has the ability to cruise slow or get up and run around 18 knots, something the 28 pacific cant do. Its a slow boat only and I did not like the stepping up and down from the salon to the bridge and down to the berth again. I like the one level of the tug. the Pacific's and the Rossy's don't have as much of a back deck as the tug 27 either. The cut water is nice and I would love to test drive one but I would have to change the berth around a little, which the factory said they would do. It does have the greatest deck seat in boating. You can face in or out of the cockpit in the flip of a seat.
My 27 would be great on the loop. 9 1/2 foot back deck, head, large berth, large table and a ton of storage. Add the ablitiy to cruise at 18 knots or run at 30 to get out of the way of storm fronts or cross large water. its a great boat.
