Narrative:

Departing runway 1 at dca with a line of thunderstorms to west and north, tower cleared us for takeoff with a right turn heading 090 degrees and 'stay clear of P56.' our charts do not have a great deal of detail on P56 boundaries and there are no electronic guidance means (ie, dca 328 degree radial when departing north up the river). I'm not sure we didn't clip the very southeast edge of P56 during our climb out and turn. A better detailed map of P56 and some electronic guidance would have helped. (Maybe a radial off armel (at dulles) not to go north of.)

Title: B737 FLC CLIPPED THE EDGE OF P56 PROHIBITED AIRSPACE DURING INITIAL DEP FROM DCA.

Narrative: DEPARTING RWY 1 AT DCA WITH A LINE OF TSTMS TO W AND N, TWR CLRED US FOR TKOF WITH A R TURN HDG 090 DEGS AND 'STAY CLR OF P56.' OUR CHARTS DO NOT HAVE A GREAT DEAL OF DETAIL ON P56 BOUNDARIES AND THERE ARE NO ELECTRONIC GUIDANCE MEANS (IE, DCA 328 DEG RADIAL WHEN DEPARTING N UP THE RIVER). I'M NOT SURE WE DIDN'T CLIP THE VERY SE EDGE OF P56 DURING OUR CLBOUT AND TURN. A BETTER DETAILED MAP OF P56 AND SOME ELECTRONIC GUIDANCE WOULD HAVE HELPED. (MAYBE A RADIAL OFF ARMEL (AT DULLES) NOT TO GO N OF.)
