Bute has a semi-open car deck with a clearance height of . Like the before her, she has bow and stern access. In addition she has a starboard vehicle ramp aft, which was used at Rothesay before the pier was converted to allow end-loading. Passenger accommodation is on two levels: the first housing forward and aft lounges with a kiosk area and toilets between, while the second level is open deck space from the twin funnels to just forward of the bridge. The bridge sits on its own perch above the open deck. A single lift connects the car deck with the lounge.
Bute has
Azimuth thruster units with engine-driven propellers, by means of a
cardan shaft, mounted on a steerable pod, protruding beneath the hull. These made her harder to position at piers than her predecessors with
Voith Schneider Propellers and led to delays in the first season. ==Service==
