The ramp at MVY is divided between an airline area and general aviation by a red line containing 'TSA-do not cross' or something similar to that. Unfamiliar with this demarcation; the pilot inadvertently crossed the line for a short distance. To prevent the situation; pilots should be familiar with ramp markings. However; this marking is not contained in [FAA Publication TC11-0020] so it would be good to include it in the next edition. A further suggestion is that Ground Control mention this situation to aircraft taxiing to the general aviation area.
GA pilot reported inadvertently crossing over the red TSA security boundary line during taxi.
