Based on my first cruise experience from Jones Inlet to New Bedford, 80nm is a long way for one day (our 2 has a comfortable motoring speed of 4 kn). We planned one overnight sail and had two overnight motorings, the first by necessity and plan, the second to take advantage of reduced headwinds and head seas. We ducked into Shinnecock Inlet twice, once for a comfortable night and once due to conked out motor (no spark, self repaired at anchorage). The night cruising was awe inspiring, with enhanced star gazing and shooting stars overhead and inability to see (moon sliver set early). I'd like to do it again under sail, with the moon lighting up the seascape... so I suggests starting the night before if conditions are favorable, and you have enough crew.
