I have done that trip many times. I believe the key is to remember you are sailing in the north Atlantic and although you may be less that a hundred miles offshore
you are "at sea".
Most trips at that time of year are non-events, outside of damp chilly air and an occasional 25 -30 kt. day. It is important to have your coastal navigation
down pat,electronics being used as a backup to your chartwork. Keep a sharp lookout, plenty of fishing
boats about and other commercial
Stay warm, once the chills set in your misery level can be significant.
