Narrative:

Departed runway 9; very shortly after lift off captain asked if we were supposed to be on an RNAV SID; I stated I thought we were on the logan 4 departure; he double checked and it was the PATSS1 RNAV departure we were cleared for on the pre departure clearance clearance; he quickly tried to reprogram FMS; but the SID page is not available after takeoff; I stated we should ask for a heading immediately so we do not miss a turn. He continued to try to program in the correct fix but could not program it correctly. ATC was talking so he could not get in a word to request a heading and explain our situation. At the first break in conversation on the frequency; controller inquired if we were on the PATSS1 RNAV departure; which we acknowledged; and then he laughed and mentioned we missed the turn at claaw by almost 3 miles; he then gave a heading turn to 210 degrees. Airplane came in late; loaded 15 people immediately after crew change and then agent stood over our shoulder the entire preflight prep asking if we were 'all set' multiple times; which we were not. But admittedly we rushed to help get out on time. I briefed the logan 4 departure; and executed it. Captain caught the error immediately after takeoff before a turn or initial fix had been crossed but failed to get in the FMS programming in time. We had every intent on asking for a heading and explaining the situation before an error was made but due to frequency congestion were unable until it was too late. No traffic in the area and no conflict with other aircraft was evident or mentioned. Avoid being rushed by agents at any cost including a 25 minute turn for them! Always double check printed pre departure clearance clearance - it's the only thing that counts; instead of trying to quickly reprogram an uncooperative FMS; ask early for heading direction and admit fault before a fix is crossed and a turn is missed. We realized our mistake very early but tried to program quickly to recover before and error occurred; time and frequency congestion were not on our side; and it was too late.

Title: An air carrier crew running an hour and a half late failed to program the FMS with the BOS PATSS1 RNAV. After takeoff the Captain realized the error; but unable to change the departure in-flight waited for an ATC vector.
