This event occurred while taxiing into the ramp between rows of aircraft for maintenance. I was pilot monitoring in the right seat. The ramp was unattended with no marshalers present. As we approached an aircraft parked to our right; I advised the pilot flying that we were very close and to proceed very slowly. We inched along at a snails pace and from my perspective we looked to have about 4 to 5 feet of wing clearance. I was watching the wing as we contacted the tail strake of the aircraft parked to our right with our right wingtip. From my vantage point I thought we were clear. I clearly misjudged the distance. In hindsight we should not have proceeded between the rows of aircraft without a marshaler. The environment was deceptive and with no taxi lines present we should have parked elsewhere.
Taxiing into ramp in left seat and was watching left side and kept left wingtip clear. Right seat pilot was watching right wing tip. Right seat pilot asked if I could come left and I did and said 'is that enough?' Right seat pilot replied yes but go slow. I did and then I felt aircraft bump and right seat pilot announced that the right wingtip had touched the aircraft on the right.There was no Marshaller when we arrived. We looked the ramp over and decided to taxi up between the rows of aircraft that were parked on the ramp. We thought we had sufficient clearance to taxi up the rows of aircraft. We were taxiing slowly to be careful and we kept the communication going between us. In hindsight; we should not have taxied down the rows of aircraft but just stopped the aircraft in front of the hanger.
Cessna CL-600 flight crew reported that the right wing tip contacted the tail strake of another aircraft while taxiing between rows of aircraft.
