C210 PLT RECEIVES SEVERAL ATC WARNINGS REGARDING CLASS B AIRSPACE WHILE FLYING OUTSIDE THE LATERAL AND VERT BOUNDARIES OF THE AIRSPACE.

Narrative

WE WERE ON A VFR FLT FROM APF TO LEE. WE DEPARTED APF AND INDICATED TO THE TWR THAT WE WOULD LIKE TO PROCEED NBOUND A COUPLE OF MI OFF THE COAST AT 1000 FT. APF TWR PROVIDED SOME TA'S AND HANDED US OFF TO RSW APCH FOR FURTHER VFR ADVISORIES. WE MADE THE SAME REQUEST OF RSW APCH AND CONTINUED NBOUND ALONG THE COAST AT 1000 FT. AS WE APCHED SRQ; WE CONTACTED TPA APCH AND AGAIN MADE THE SAME REQUEST TO CONTINUE NBOUND OFF THE COAST UNTIL WELL N OF TPA CLASS B AIRSPACE. WE WERE PROVIDED A XPONDER CODE AND ASKED TO REMAIN CLR OF CLASS B AIRSPACE. AS WE APCHED THE TPA CLASS B AIRSPACE WE CONSULTED A TPA/ORL VFR TERMINAL AREA CHART; AND 2 INDEPENDENT GPS MOVING MAP SYS. OUR RTE APPEARED CLRLY OUT OF CLASS B AIRSPACE SINCE WE WERE TO CONTINUE TO FLY A COUPLE OF MI OFF THE COAST AT 1000 FT. HOWEVER; DURING OUR FLT ALONG THIS RTE WE RECEIVED SEVERAL WARNINGS FROM TPA APCH TO REMAIN CLR OF CLASS B AIRSPACE AND ONE VECTOR. WHEN ASKING ATC FOR THE REASONS OF THESE WARNINGS AND THE VECTOR; THEY RESPONDED THAT WE HAD NOT VIOLATED THE CLASS B AIRSPACE BUT WERE IN THE PROX AND THEY JUST WANTED TO MAKE SURE THAT WE WOULD NOT VIOLATE THE AIRSPACE. OUR REMAINING FLT WENT WITHOUT INCIDENT. WHILE WE CERTAINLY APPRECIATE THE CTLR'S EFFORTS TO KEEP US OUT OF CLASS B AIRSPACE; THE CONTINUOUS ADMONITIONS SERVED ONLY TO CONFUSE US. ACCORDING TO OUR INFO; WE WERE AT ALL TIMES WELL CLR OF CLASS B AIRSPACE AND THE CONTINUOUS IMPLICATIONS THAT WE WERE ENCROACHING ON THE CLASS B AIRSPACE SERVED ONLY TO MAKE US QUESTION THE ACCURACY OF OUR CHART AND OUR EQUIP. ALSO; IF ENCROACHMENT ON CLASS B AIRSPACE WAS SUCH A GREAT CONCERN; AND SINCE THEY HAD US TAGGED AND IDENTED AND WERE IN CONSTANT COMS WITH US; WHY NOT JUST ISSUE A CLRNC INTO CLASS B AIRSPACE AND AVOID ALL THE FREQ CONGESTION?
