I'm with everyone else on this. You can't assume that you will dock on time, and disembarking is a lengthy process. Either find another flight or stay overnight if you have to. Personally if I'm checking bags I like to try to be at the airport at least 2 hours prior to departure because you never know how long the lines will be.
