Did you launch from the ramp on the mainland side of the bridge?
Just checked it out on Google Earth - looks like there's a nice sandy beach next to the pier there. Might have to check that out as a place to launch my H16 one day.
I didn't launch at the ramp, although it looked pretty nice. Coming from the North, we passed the ramp on the right and went to the small island in the middle next to the pier on the left. I used my beach wheel cart and launched from the beach. It was very, very shallow at low tide. ( about 6 inches) and it was some low spots in the sound to look out for while sailing.
If I launched at the ramp, I would have had to lower my mast or go to the draw bridge and have them open the bridge. I choose the path of least resistance. The beach launch was fine. I was able to back the trailer down very close to the water and there was plenty of park for a trailer. I went on a Monday, so not sure how it would be during the weekend.
