Yes you can, but you aren't really praying to St. Gabriel as much as you are asking St. Gabriel to pray for you or intercede for you (Get him to bring your prayers to God).
This goes for all the other saints as well.
In Christianity, prayers are directed to saints to ask for their intercession with God. While Saint Gabriel is a prominent figure in the Bible as the angel who announced the Annunciation to Mary, he is typically not invoked in prayer since he is seen as an angelic messenger rather than a human intercessor.
St. Gabriel is an archangel and not a sailor.
