An small aircraft had been placed on floats of the fixed or no wheels type. The aircraft and floats were on a 3 wheel trailer used for transport and launch takeoff. Takeoff was made by myself as pilot on the parallel taxiway along runway 25 beginning midfield. After liftoff from the cart, the captain slowly turned to the left striking the airport's lighted windsock located at the approach end of runway 7 between the runway and taxiway in grass median area. Launching of sea/float planes from land is commonly done from carts, however, the cart should have its castered steerable wheel(south) semi-locked in straight ahead position and a brake after aircraft liftoff to stop the cart. Cadillac's airport manager was contacted by me and has issued a cart takeoff use policy to the local maintenance facility. Callback conversation with reporter revealed the following information: the FBO had to pay for the damages to the windsock lights. The launch trolley was modified. The castering nosewheels were limited to about 15 degrees of caster and an electric trailer brake was installed that would apply light braking when the aircraft rose about 6 inches above the trolley.

Title: FLOATPLANE LAUNCHING DOLLY FOR USE ON LAND VEERED INTO THE WINDSOCK AND DAMAGED SOME LIGHTING AFTER THE ACFT HAD LIFTED OFF IT.
Narrative: AN SMA HAD BEEN PLACED ON FLOATS OF THE FIXED OR NO WHEELS TYPE. THE ACFT AND FLOATS WERE ON A 3 WHEEL TRAILER USED FOR TRANSPORT AND LAUNCH TKOF. TKOF WAS MADE BY MYSELF AS PLT ON THE PARALLEL TXWY ALONG RWY 25 BEGINNING MIDFIELD. AFTER LIFTOFF FROM THE CART, THE CAPT SLOWLY TURNED TO THE L STRIKING THE ARPT'S LIGHTED WINDSOCK LOCATED AT THE APCH END OF RWY 7 BTWN THE RWY AND TXWY IN GRASS MEDIAN AREA. LAUNCHING OF SEA/FLOAT PLANES FROM LAND IS COMMONLY DONE FROM CARTS, HOWEVER, THE CART SHOULD HAVE ITS CASTERED STEERABLE WHEEL(S) SEMI-LOCKED IN STRAIGHT AHEAD POS AND A BRAKE AFTER ACFT LIFTOFF TO STOP THE CART. CADILLAC'S ARPT MGR WAS CONTACTED BY ME AND HAS ISSUED A CART TKOF USE POLICY TO THE LCL MAINT FACILITY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE FBO HAD TO PAY FOR THE DAMAGES TO THE WINDSOCK LIGHTS. THE LAUNCH TROLLEY WAS MODIFIED. THE CASTERING NOSEWHEELS WERE LIMITED TO ABOUT 15 DEGS OF CASTER AND AN ELECTRIC TRAILER BRAKE WAS INSTALLED THAT WOULD APPLY LIGHT BRAKING WHEN THE ACFT ROSE ABOUT 6 INCHES ABOVE THE TROLLEY.
