How much size of luggage restriction taking ferries from hk to macau

Hello. We want to know, what are the luggage restrictions size for riding ferry to macau? We planning to take turbo jet to macau.
is it ok to handcarrry your luggage? But we see on turbojet website they allow 1 hand carry luggage for 60x20x35 cm. but my luggage over size : 60x26x39 cm. can I still carry my luggage for free?
is the turbojet staff strictly check the luggage size?
