Put the boat in in Westerly and drive out around Napatree. look on the chart for "the humps" just east of there. Three way eels over these humps. You'll get your first keeper. Do it about 2 hours after high tide at Watch Hill. hang on though. Your first keeper there could be 4 feet long!!
This location and technique will do you well till atleast mid November and maybe later depending on the weather.
