Questions to ask a dive operator before booking

Before you pay for a dive or snorkel trip, the most useful thing you can do is ask the operator clear questions and listen closely to the answers. The crew, the boat, the equipment and the briefing will shape your safety for the whole day, and the answers often tell you more than the brochure does. Ask about group size, the guide-to-diver ratio, staff qualifications, emergency equipment, the safety briefing, equipment care and what happens if the trip is cancelled or the weather changes.

Good operators usually welcome these questions and will often answer them in writing if you ask. A reluctant or vague reply is worth noting before you commit.

Group size and guide ratio

Ask how many divers or snorkelers will be in each group and how many guides or instructors will be on the trip. The ratio matters because a single guide can only watch so many people at once, and the larger the group, the harder it is for everyone to stay close to a buddy or the guide. On busy days, popular snorkel spots can fill with boats, so ask how the operator manages crowding at the site.

Ask what happens when a diver needs extra help, such as a problem with a mask or buoyancy, and whether a staff member will stay with that person. Also ask how the operator splits large groups. A well-run trip can send smaller groups to different parts of a site so that people are not crowded around the same animal or the same entry point. Ask whether the operator caps the number of guests on a trip, and whether it will tell you before you pay if a departure is already full.

Qualifications and emergency readiness

Ask which training agency certifies the guides and instructors, and whether their certifications and first aid training are current. Ask whether the crew has been trained to give emergency oxygen, and whether oxygen equipment is carried on board, where it is stored and how often the crew practices using it. Emergency oxygen is widely recommended on dive boats, so it is a fair question to ask directly.

Ask how the crew would contact emergency services from the site and how long the trip back to shore would take. Also ask how the operator checks its equipment. Rental regulators, buoyancy devices and cylinders need regular inspection and servicing at set intervals, and staff should be able to tell you when each item was last checked. A reputable operator can describe its routine without difficulty.

Briefings, equipment fitting and the day's plan

A pre-dive or pre-snorkel briefing is where most of the safety information is shared, so pay attention to what it covers. A complete briefing usually includes:

• the site, the expected depth and the current
• the entry and exit points, and how the boat will recover people
• the hand signals and how buddies will stay together
• the turn-around point or time, and the emergency procedure

A briefing that is rushed or skips these points is a warning sign. Ask whether staff will check your certification card and recent logged dives before you enter the water, and what they do if your recent experience falls short of what the site needs. Also ask whether they will check rental fit and your weight setup, and who on the boat is responsible for counting people in and out of the water. For snorkel trips, ask where the boat will anchor and how the guide will call people back to the boat.

Also ask what the operator does if conditions change during the day. Crews should be able to explain when they would shorten a dive, move to another site or cancel the rest of the trip, and who makes that call. A clear answer shows that the decision belongs to a trained, accountable person rather than to the pressure of a full boat.

Cancellation, changes and written terms

Ask for the cancellation and rescheduling policy in writing, and check whether it covers weather, sea state and medical reasons. Operators often cancel trips for unsafe conditions, so ask what happens to your booking in that case and how much notice they usually give. Ask whether you can change the date or site if your health or fitness changes before the trip.

Read the terms before you pay. Deposit and refund rules vary widely; if the terms are unclear, ask for clarification in writing or check with a consumer advice service. Medical forms are a separate matter. A physician is the right person to advise on whether you are fit to dive, so if a form asks about a condition you have, speak to your doctor before you sign.

The best operators will answer these questions without making you feel rushed. Your aim is not to catch anyone out. It is to confirm that the group size, the crew and the safety routines match what you expect for your own level of experience. If the answers are clear, you have a sound basis for booking. If they are vague, ask again or choose another operator.
