I think I should add some info having done more than 50 crossings on various bikes...they know how to strap your bike down, in gear, side stand down, no centre stands, they apply your front brake with a rubber band, forks about 3/4 compressed and apply 2-3 tie down straps...it's not there first rodeo so leave them to it. Some riders have complained about damaged fork seals over my many trips, all typically popular cruiser style bikes. Never had any troubles on S10, Vulcan 2ltr, Ducati Diavel, KLR 650 & FJR1300 in all my trips. So park where and how they tell you to, grab your keys and pre packed overnight/day bag, helmet and jacket and enjoy your passage.
Special Note: Decks can be slippery and the Elephants Feet (tie down points) on the deck are to be avoided.
When disembarking, remember to undo the off-side tie down first, thats the one opposite your side stand. I have seen others not do this and in panic thinking their bike is about to tip over have either pushed their bike over into the bike next to them and/or done an injury trying to catch their bike.
I hope you all enjoy the motorcycle nirvana that Tassie is, I know I did for the 4yrs I lived there
