I have been that buddy. On a calm morning off the west shore of Maui, I floated next to my partner, both of us face down, breathing through full face masks and watching reef fish. Ten minutes later she lifted her head and said she felt strange, a little winded. We swam to shallow water. She recovered, but that moment changed how I think about the buddy system in snorkeling. The buddy protocol I learned in scuba class did not prepare me to read the signs that matter on the surface.
The buddy system is the most repeated safety advice in snorkeling and the least practiced. Part of the problem is that snorkelers inherited it from scuba without adapting it to the surface. We also define a buddy as someone nearby, not someone with a specific job. The result is pairs of people floating ten feet apart, each assuming the other is fine because nobody is thrashing. Recreational snorkeling is not a benign, low-risk activity. That is true for experienced and inexperienced swimmers.
Where the buddy system came from
Scuba instructors formalized the buddy system in the mid twentieth century. They needed a way to handle air supply failures, entanglement, and regulator malfunctions. The model works because the risks are mechanical and often visible. A pressure gauge drops, a second stage pulls free, a buddy signals for air. The response is close, physical, and task-loaded. Two divers stay near each other, share air, and solve the problem together.
Snorkeling borrowed the phrase and kept the slogan. But the risk profile is different. Snorkelers stay at the surface, breathe through a tube, and have no air gauge. The most dangerous event in snorkeling is a quiet physiological cascade that can happen without a single splash.
Why the surface changes everything
At the surface your chest sits under water pressure, and you breathe through a narrow tube. Every inhalation takes a little more effort than breathing on land. For most people that extra effort is minor. For some, under certain conditions, the resistance can create enough negative pressure in the lungs to allow fluid to move into the alveoli. That condition is Snorkel Induced Rapid Onset Pulmonary Edema, or SI-ROPE.
The Snorkel Safety Study final report, published in June 2021, identified SI-ROPE as a common factor in snorkel-related drowning and near-drowning events. The study listed three risk factors for developing SI-ROPE: the degree of the snorkel's resistance to inhalation, certain pre-existing medical conditions, and increased exertion. That last one matters for buddy teams. The moment someone starts working hard against a current or swimming a long stretch, the risk rises.
The typical sequence is specific and fast. Sudden shortness of breath, fatigue, loss of strength, a feeling of panic or doom, a need for assistance, then diminishing consciousness. Almost all events took place where the person could not touch bottom. Aspiration was rarely the trigger or even a factor.
That is the core problem for the buddy system. A person in the early stages of SI-ROPE does not look like a drowning person in a movie. There is no waving, no shouting, no splashing. There is only a quiet loss of strength. If your buddy is ten feet away, face down, and you are both watching fish, you might not notice until it is too late.
The signs a buddy must know
Survivor accounts give a clear picture of how a snorkeling emergency starts. The first symptoms are shortness of breath, progressive fatigue, and weakness. Diminishing mental alertness follows. Many survivors described extraordinary effort just before the event: swimming hard against a current, a long surface swim, or an intentional workout in the water.
A snorkel buddy needs to watch for these signs:
- sudden stops to rest more often than usual
- a partner lifting their head repeatedly or removing the mask
- drifting away from the group without correcting course
- floating motionless face down for more than a few seconds
- not responding to a call or a tap on the shoulder
If you feel shortness of breath, dizziness, or unusual fatigue while snorkeling, remove your mask, roll onto your back, signal for help, and get out of the water immediately. Do not push through it. The study's proposed safety messages put this plainly. Shortness of breath can be a sign of danger. Stay calm, remove the snorkel, breathe slowly and deeply, stand up, get out.
A snorkel-specific buddy protocol
The buddy system starts with a rule that has not changed. Never snorkel alone. Then give the buddy a specific job before you enter the water. Three parts cover the moments where most pairs drift apart.
The pre-swim brief
Two minutes on shore before you get wet. Agree on the route, the entry and exit points, the time limit, and the water conditions. Pick a lifeguarded beach when possible. One person leads and sets the pace. The other watches the leader for signs of fatigue. Confirm that both of you are comfortable in the conditions and can touch bottom at the start. If you cannot swim, do not snorkel. If either person has a heart or respiratory condition, get a doctor's okay before snorkeling. If you just landed from a long flight, wait two to three days. For kids, adult supervision is non-negotiable. Check mask fit and seal in shallow water first.
In-water check-ins
The snorkel safety guide recommends checking your location every 30 seconds to avoid drifting away from your base. Use the same interval for your buddy check. During each check-in, do these three things in order:
- Lift your head clear of the water.
- Find your buddy and make eye contact.
- Confirm you are both still near the planned route.
If you cannot see your buddy's eyes, you are too far apart. Rotate the lead every few minutes so the stronger swimmer does not slowly pull away.
The exit and response plan
Agree before you enter what happens if either of you feels off. The signal might be a raised hand, a tap on the head, or a call. If one buddy signals, the other closes the distance and helps them roll onto their back. Remove the mask, breathe slowly, and signal for help if needed. Get out of the water right away.
If a buddy becomes unresponsive face down, shout for help, approach from behind, roll them onto their back, and get them to shore or to a lifeguard while someone calls emergency services. Start CPR only if you are trained and it is needed.
One more rule from the study belongs in every buddy brief. Stay where you can touch the bottom comfortably until both of you feel confident. Do not exercise or increase exertion while breathing through a snorkel.
Where your gear fits, and where it doesn't
A buddy can only do so much if the gear is working against you. Inhalation resistance is one of the factors linked to SI-ROPE. That is why Seaview 180° V3 Full Face Snorkel Mask uses the patented FlowTech Advanced Breathing System. In third-party testing, the V3 performs up to 600% more efficiently when breathing compared to other leading full face masks. The design goal is lower work of breathing on every inhale. Less negative pressure in the lungs is one way to reduce the chance of SI-ROPE.
But gear is not a safety guarantee. The V3 is recreational equipment designed for surface snorkeling use only. It is not medical or life-saving equipment, and no full face snorkel mask is certified safe. Do not use it for diving, freediving, or scuba. Proper sizing and seal are critical for performance and comfort. Environmental factors such as waves, currents, water temperature, and exertion affect breathing comfort. If you experience discomfort, dizziness, or breathing difficulty, exit the water immediately. Follow all included instructions and warnings.
For weaker swimmers or anyone who wants extra flotation, the Palawan Snorkel Vest can help. It is a flotation aid for swimmers, not a certified life jacket or life preserver. Use it only if you know how to swim. Pair the vest with the buddy protocol and you have a much stronger safety net.
Put the buddy back in the buddy system
The snorkel buddy system needs its own rules. Scuba gave us the habit of staying together. The surface gave us a different set of risks. A good snorkel buddy knows the quiet signs, checks in every 30 seconds, and has a plan to get their partner out. That is the standard I wish I had learned before that calm morning off Maui. No piece of gear and no buddy can replace your own judgment.
See how the Seaview 180° V3 is designed to support comfortable surface breathing. Then brief your buddy before you get wet. The reef will still be there.
