Before attempting one, ask a certified instructor or the boat crew to watch your first giant stride entry. What is a giant stride entry? It is an upright water entry where a fully equipped diver takes one large, controlled step off a stable platform while keeping the mask, regulator, and dangling gear in place. Start slowly.
This entry is common from dive boats with a low swim platform or a designated side gate, especially when the water surface is clear and the crew wants divers to enter one at a time. It is not a jump. Your body stays vertical, one leg goes forward, and your equipment remains close to you as you enter.
What is a giant stride entry and when is it used?
A giant stride entry gets you into the water without sitting down first, which can be useful when you are wearing a steel cylinder, have limited room on the platform, or need to clear the entry area efficiently. The goal is simple. You enter feet first with enough separation between your legs that the water does not force your tank or BCD upward into your head.
The entry works best when the platform is close enough to the water that a normal step is possible, the surface below is free of divers and obstructions, and the operator has told you it is the expected method. Conditions matter. A tall freeboard, a hard-sided inflatable, surge against the hull, or a rough sea can change the safest entry method.
Boat procedures take priority over generic advice because crew members know their ladder position, propeller safety procedures, current, and how divers will be picked up after the dive. Listen first. If the crew asks for a seated entry, a back roll, or a controlled ladder descent, use that method instead.
Prepare before you reach the edge
Most awkward entries start before the diver moves. Check that your cylinder is secure, your BCD is inflated enough to float you after entry, and your regulator is in your mouth and flowing normally. Breathe normally. Do not rely on holding your breath during any scuba entry.
Secure anything that can swing or catch water, such as a console, alternate second stage, camera, or clipped accessory. Loose gear hurts. If you carry a camera, ask the crew whether they will hand it down after you enter, since managing a large housing while protecting your mask and regulator adds unnecessary distraction.
Look down into the entry zone only after the crew indicates it is clear. Check for another diver surfacing, a trailing line, a tender, or a swell that could move the boat toward you. Wait. Never enter until the person controlling the entry gives you the signal.
Use the hand position your instructor taught and your hose routing supports. A common method is to hold the mask frame and regulator firmly against your face with one hand, while the other hand pins the console and any loose hoses against your torso. Keep control. If your equipment layout differs, practice the correct hold in shallow water with a certified instructor before relying on it from a boat.
Giant stride entry step by step
- Confirm the entry is clear. Make eye contact with the crew member or buddy managing the platform, then wait for the agreed signal. Do not assume. A clear surface can change in seconds when divers are ascending near the boat.
- Place your fins at the edge. Stand upright with both fins flat and stable, with your toes near or slightly over the edge if the platform design allows it. Keep your feet apart. Do not balance on one fin while trying to adjust a strap or camera.
- Hold your mask and regulator. Press the mask gently but securely to your face and keep the regulator mouthpiece in place. Keep breathing. Use your free hand to control gauges, hoses, and an alternate second stage so they do not strike you or snag on the platform.
- Look ahead, not straight down. Keep your chin level and your body upright rather than curling forward toward the water. Stay tall. Looking ahead helps prevent a hesitant half-step that can pull you off balance at the edge.
- Take one big forward step. Move your leading leg well out in front of you as though stepping over a wide puddle, while leaving the other leg behind briefly. Commit to it. A small step often lets the water push the cylinder and BCD upward harder because your legs close too soon.
- Keep your legs apart through impact. Let the trailing leg follow naturally, but avoid snapping both feet together before you are submerged. Stay vertical. The wide stance creates a stable entry and reduces the upward shove of water between your legs.
- Surface, signal, and move clear. Once you are floating, establish buoyancy, check that your mask and regulator are comfortable, and give the agreed OK signal. Then move away. Clear the entry zone promptly so the next diver has room and the boat crew can track everyone.
For a practical dry-run, stand on a low step without scuba gear, hold one hand lightly to your face and the other against your waist, then rehearse a wide forward step without jumping. Keep it dry. This is only a movement rehearsal, not a substitute for supervised water-entry training.
Common mistakes that make entries rough
The most common mistake is taking a timid little step. That puts your feet close together on impact, and water can drive the BCD and tank upward abruptly. Make one deliberate step. You do not need to leap outward or launch yourself away from the boat.
Another problem is forgetting a loose console or alternate regulator. A swinging console can hit your face, while an unsecured hose can catch on a rail or pull uncomfortably when you enter. Tuck it in. Check the same few items before every entry until the routine becomes automatic.
Divers also sometimes look down, bend at the waist, and enter at an angle. That can flood a poorly sealed mask or turn a controlled step into an unsteady fall. Keep upright. If you feel rushed, signal the crew that you need a moment rather than forcing the entry.
When to choose another entry
Do not use a giant stride just because it is familiar. A seated entry may be better when the platform is very low, you need more stability, or the operator directs it. Follow the briefing. A back roll is often used from rigid inflatable tubes or benches where stepping forward is not practical.
Skip the entry and tell the crew if you feel dizzy, have a gear problem, cannot seal your mask, or are unsure where you will surface. Stop there. A few seconds of communication is safer than entering with a problem that could become harder to manage in waves or current.
People with joint pain, balance limitations, recent injury, or concerns about the load of scuba equipment should discuss diving and entry methods with a doctor and a certified diving professional. Bodies differ. A technique that feels easy for one diver may not be suitable for another.
Frequently asked questions
Do I inflate my BCD before a giant stride entry?
Usually, divers enter with enough air in the BCD to establish positive buoyancy at the surface, but the exact amount depends on your exposure suit, weights, cylinder, and the operator’s procedure. Confirm it. Practice your personal buoyancy setup with a certified instructor rather than copying another diver’s inflation level.
Should I jump away from the boat?
No. Take a large forward step, then let gravity carry you into the water in a vertical position. One step. Pushing hard away can make you lose control, especially when wearing fins on a narrow or wet platform.
Why do divers keep their legs apart?
A wide stride reduces the upward force of water between closely spaced legs and helps keep the cylinder and BCD from riding up sharply on impact. It also gives you a more stable body position. Stay upright.
Can I use a giant stride with a camera?
You can if you have been trained to manage the housing and the operator permits it, but many divers hand cameras down or receive them after entering. Less to hold. Protecting your airway and maintaining control of your mask come before camera handling.
What should I do if my mask floods after entry?
Stay calm, keep breathing from your regulator, establish positive buoyancy, and use the mask-clearing skill you learned during training when conditions allow. Signal your buddy or crew if you need help. Do not descend until you are comfortable and ready.
