The gear you effectively need depends on the type of Whale Watching tour you are envisaging. Even if most people think of whale watching as a boat-based activity, it is also possible sometimes to observe whales, dolphins and porpoises from the shore and from the air. Clothes As equipment is especially important for water-based Whale Watching, the following list applies mostly to boat tours. Life Jacket (normally provided by the Whale Watch Operator) Wind/waterproof jacket Wind/waterproof trousers Hood or hat Rubber-soled shoes Accessories Sunglasses Camera and/or Camcorder Sunscreen Waterproof bag Binoculars Agents for prophylaxis of seasickness Professional items Notebook and pen (or waterproof smartphone/tablet) Stopwatch Sunscreen Hydrophone Rangefinder Other suggestions It is always a good idea to wear layers, sometimes lots of them, depending on climate and weather. Remember that boats create their own, apparent wind while navigating. Always take some sunscreen with you, even if the sky appears to be very cloudy. Conditions can change quickly at sea and, as a general rule, cloud cover is more likely to be substantial on land than it will be on the ocean. This is especially true on small, oceanic islands.
