Narrative:

I departed myf VFR and did a left downwind departure. On climb out I was issued a TA and diverted south then back to an easterly heading following V66. I then asked for and received a frequency change to see tower. Upon contacting see I was issued additional traffic and advised to turn north. I turned south to pass the traffic on the right. Shortly after doing so see said I was in the (san diego) class B. I was at 3100 ft at the time, but I believe I was past the point where the floor of the class B goes to 3500 ft. After reviewing the GPS track, I did get to the mzb 087 degree radial, but cannot discern from the chart exactly where the line between the class B floor of 3000 ft and 4800 ft is, so I may have violated the class B. The san diego tac is very unclr where those zones are, so I am still unsure if I violated or not. The area between mzb 084 degrees and the pgy 286 degrees of the class B is not documented well on the chart. In retrospect, I should have taken a right downwind departure and flown directly over see.

Title: PIPER PLT ENTERS CLASS B INADVERTENTLY.

Narrative: I DEPARTED MYF VFR AND DID A L DOWNWIND DEP. ON CLBOUT I WAS ISSUED A TA AND DIVERTED S THEN BACK TO AN EASTERLY HEADING FOLLOWING V66. I THEN ASKED FOR AND RECEIVED A FREQ CHANGE TO SEE TWR. UPON CONTACTING SEE I WAS ISSUED ADDITIONAL TFC AND ADVISED TO TURN N. I TURNED S TO PASS THE TFC ON THE R. SHORTLY AFTER DOING SO SEE SAID I WAS IN THE (SAN DIEGO) CLASS B. I WAS AT 3100 FT AT THE TIME, BUT I BELIEVE I WAS PAST THE POINT WHERE THE FLOOR OF THE CLASS B GOES TO 3500 FT. AFTER REVIEWING THE GPS TRACK, I DID GET TO THE MZB 087 DEG RADIAL, BUT CANNOT DISCERN FROM THE CHART EXACTLY WHERE THE LINE BTWN THE CLASS B FLOOR OF 3000 FT AND 4800 FT IS, SO I MAY HAVE VIOLATED THE CLASS B. THE SAN DIEGO TAC IS VERY UNCLR WHERE THOSE ZONES ARE, SO I AM STILL UNSURE IF I VIOLATED OR NOT. THE AREA BTWN MZB 084 DEGS AND THE PGY 286 DEGS OF THE CLASS B IS NOT DOCUMENTED WELL ON THE CHART. IN RETROSPECT, I SHOULD HAVE TAKEN A R DOWNWIND DEP AND FLOWN DIRECTLY OVER SEE.
