Under OB power & current was ~7 knots out through the bridges to Raritan Bay. Circled too close to pilings around the RR bridge and got hung up on them briefly, acquiring some creosote on port side, but got free and retreated back into the creek. Finally the 35 highway bridge was open enough for my 40' mast & I got through, as RR bridgetender was hollering at me on 13 to hurry up cos train was coming. A stressful few minutes there. (RR bridge is inside highway 35 bridge at that location.) As I passed under highway bridge the bridgetender asked me to say again the name of my vessel. I suppose he put me down in his book of bad examples of seamanship?Well don't leave us hanging! tell us the whole story!
