VHF should be fine if it's in good working order.
A good radar
reflector as well but just keep a good lookout for fishing
boats at night, they often are running autopilot
and not really looking for anything smaller than a freighter. Then again they have right of way if on a haul or run.
Sometimes helps to hail them if your not sure of their course.
traffic in and out of NY changeable, commercial ships going into and out of Narragansett Bay usually sit Southeast of BI for pilot boat but some commercial tugs run barges up along Long Island
north of BI between the island and shore heading for Buzzards Bay and to the CC canal, worth looking out for at night since the tow cables
can be up to 3/4 mile long depending on sea state and size of load.
Not a bad run though weather
that time of year is wide ranging and the water's still cold.
Will be sailing to Nantucket
around then from RI, I'm bringing shorts and cold weather gear
, you never know.
