Narrative:

The first officer obtained a clearance from austin clearance delivery while I listened. I heard that we were cleared via the centex 3 departure; navis transition; direct lufkin; then 'as filed.' when I read the departure procedure; I saw the navys transition and input that transition into the FMS. The first officer also heard something that he thought sounded like navis; and when we reviewed our FMS routing; we agreed that we had the correct route in the FMS. However; after takeoff; we were cleared direct hookk intersection. Hookk was not a fix on our departure procedure; and I told ATC that. The controller instructed us to fly a heading. Controller then told us that hookk intersection was 17 miles off the 088 degree radial from centex. Controller gave us a heading to intersect the departure. When I realized hookk was on a different transition than the one we had in the FMS; I asked which transition we were supposed to be on. Controller said the navasota transition. I changed the departure procedure to the navasota transition; and no further events occurred. The reason for the confusion was a miscommunication between clearance delivery and the flight crew. We both thought it was feasible for the navys intersection to be pronounced like navis. Also; there is a box on the commercial chart that has 'navys transition' in big letters on the middle of the page; but the only way to notice the navasota transition is to read that tnv is the navasota VOR. Also; in the FMS; the navasota transition is listed as tnv; so the only transition that initially looked like navis was the navys. Being unfamiliar with the airport; and hearing the clearance improperly; resulted in us thinking that we had been cleared with the wrong transition. I think that one of the transitions should be renamed to avoid the possibility of people getting the two confused.

We both thought it was feasible for the NAVYS Intersection to be pronounced like NAVIS. Also; there is a box on the commercial chart that has 'NAVYS TRANSITION' in big letters on the middle of the page; but the only way to notice the Navasota transition is to read that TNV is the Navasota VOR. Also; in the FMS; the Navasota transition is listed as TNV; so the only transition that initially looked like NAVIS was the NAVYS.
