Earls Coln have a nice TB10 (G-TZEE) @ £125/hr wet. When you check out they will tell you to run it at 2150*21.5 inches! When your off on your own run it at 24/24 gives another 15kn, but probably burns a gallon or so more an hour, but well within the engines operating parameters. She was cruising at around 115kn at the second setting, which isn't that quick for a 180, but they are much more comfortable and spacious than a spammy! They also impress the girls more than a 100 year old 172 with the plastic falling off the door

2. If its windy the doors are very fragile when open.
