Using your gloves alone is not enough to protect your seat/paintwork. They are put under pretty big tension and it would knacker any glove with carbon inserts for example.
The ferry guys know what they're doing. They usually put a thick layer of cardboard or rug over your seat first. Make sure they do or the strap can split the seat fabric as happened on a mates Bandit6.
The other thing is......
Deckpaint! Be careful, if it's wet it's treacherous! Gentle back brake only. The word of experience!
