Normally--always--I'm quiet in the marsh, but on this occasion I lost all track of time, realized I was late for dinner, and had to scoot. My faithful 3.5hp 2-stroke will plane very nicely if the dingy is light and well-trimmed.
Because of extensive shallow water, anchoring a cruising boat neat the island is basically impractical unless your draft is quite shallow in which case there are a number of nice coves. For the rest of us, the Summers Cove marina makes a good staging ground, just a fraction of a mile from the park. You will nearly pass the marina entrance before it is clearly visible. Just keep an eye to the right for the obvious opening.
I don't know how to communicate silence in a photograph. Nothing but a light hiss of the wind in the reeds.
