He emphasizes that non-swimmers should always book a snorkeling tour with a licensed captain, as they are trained to handle emergencies and understand local weather and currents.
Additionally, choosing an operator that provides extra flotation devices, such as large rescue floats or ring buoys, and snorkel vests is crucial for comfort and safety.
It is also important to select a location with a lifeguard and communicate with them about being a non-swimmer to get personalized advice on safe snorkeling conditions.
For extra preparation, Dr. Zimmerman recommends enrolling in free online training offered by Scuba Schools International to learn about the equipment and basics of snorkeling.
