On July 3rd, I launched from the just outside the swimmer's beach area at Hingham Harbor Park. I wanted to launch over near the boat ramp (channel), but couldn't find temp. parking to drop the boat off, so I parked way over near the swimmers area and walked the boat down the beach to the water. High tide was around 10 AM and I launched at 2 PM. Based on my experience, I wouldn't recommend anything more than 3 h after high tide unless you launch at the boat ramp. Most of the beach was okay, but the last 40 ft was ankle deep sucking mud that really stuck to you. Once afloat, the non-channel area was maybe 1.5 ft deep. I am sure that at low tide you would be less than 1 ft. Once past Button Island though or in the channel, water depth was not an issue. Have fun. TheBigYaker
