Spend a half or full day on the water — with someone else playing skipper, fish-finder and first mate. More than a dozen party fishing boats depart from Captree State Park in Babylon in hot pursuit of fluke, bluefish or monster-sized striped bass in the Great South Bay. Others set sail all along the coastline, from Port Washington to Greenport on the North Shore and from Point Lookout to Montauk on the South Shore. Boats depart mornings, afternoons and evenings. Many require no reservations, but if you have a large group, be sure to call ahead. For private charters, reservations required. Fees and amenities vary, so call or check website.
