Start with a conversation, not a shopping list. Before you leave for Montauk, ask your boat what is included, when to arrive, and what you can bring aboard. Rods, tackle, food and cooler rules vary by trip.
Pack a light layer and a windproof outer layer, even when the shore feels warm. Comfortable shoes with a secure grip, a hat, sunglasses, sunscreen, drinking water and a small snack make a simple starting point. Keep the things you need during the trip in a compact bag.
If you are bringing your own gear, tell the operator what you have. A familiar rod may be all you need, or the crew may suggest a rental that better suits that day’s trip. Ask about rigging and bait before buying extras.
Check the departure details again before setting off. Give yourself time to find the dock, park and meet the crew. The best thing to bring aboard is a little room in the schedule.
