You’re at the airport, your group is excited, and the first text from the dive shop hits: “Tanks ready – want to pick up now?” That’s when the practical question shows up fast: can you fit scuba tanks in a rental car without playing gear Tetris in the parking lot.
On Bonaire, the answer is usually yes – but the best choice depends on how many tanks you’re moving, how many people are in the car, and whether you’re also hauling fins, weights, and wet gear for multiple days. Below is a real-world way to think about it, with the trade-offs spelled out so you can book a vehicle once and feel done with it.
Can you fit scuba tanks in a rental car on Bonaire?
Yes, you can fit scuba tanks in a rental car in most cases. The bigger question is whether you can fit them comfortably and safely while keeping seats usable and your gear from rolling around.
Most divers on Bonaire are transporting standard aluminum 80s (AL80s) and soft gear bags. A single AL80 is manageable in almost any vehicle with a trunk or a back seat. The moment you get into two divers doing two-tank days, or you’re carrying tanks plus camera rigs and coolers, vehicle size starts to matter.
Also, Bonaire driving is easy, but your gear gets sandy, wet, and salty. A vehicle that lets you load and unload quickly – and that won’t make you panic every time a dripping wetsuit touches upholstery – is often the difference between “vacation logistics” and “vacation.”
What actually determines if tanks will fit
People sometimes picture “tank length” as the issue. In practice, these are the things that decide it.
How many tanks and for how long
If you’re only picking up two tanks to do a morning shore dive, you can make almost anything work. If you’re doing a full day loop (north sites, lunch, then another dive) you’ll probably have extra gear: dry clothes, towels, water, maybe a small cooler, maybe a save-a-dive kit. Space goes fast.
How many passengers
Two divers in a compact car can put tanks in the back seat and still be fine. Add a third person, and now you need that seat – which pushes tanks into the trunk. Trunks are workable, but the opening can be the limiting factor even when the trunk itself is decent.
Tank type and “extra stuff”
Steel tanks and larger sizes take more room and feel heavier to lift in and out repeatedly. Many divers also travel with bulky BCs, long fins, and big roller bags. The tanks might fit, but you may not like how cramped it feels with everything else.
Wet gear reality
On an island dive trip, gear stays wet. Vehicles with open beds or easier-to-clean interiors reduce stress. If you’re the type who wants to keep everything contained and secure, enclosed cargo space may feel better – but you’ll want to think about airflow and keeping things from mildewing.
What fits best by rental car type
Every fleet is a little different, but these are reliable expectations for common rental categories on Bonaire.
Economy cars and small sedans
For one or two divers: usually fine for a couple of tanks plus soft gear, especially if you’re willing to use the back seat.
For three or four people: it gets tight quickly. You can still transport tanks, but you’ll likely sacrifice comfort or end up stacking gear.
The common pain point is trunk access. Sometimes the trunk opening is narrower than you expect, and that turns “it fits” into “it fits if we angle it perfectly and nothing else is in there.” If your plan includes daily diving, a smaller car works best for couples traveling light.
Mid-size sedans
This is the “easy mode” option for two divers who want enclosed space. You typically get a more usable trunk opening and a back seat that can handle extra items without feeling overloaded.
If you’re doing two divers plus a non-diving passenger, a mid-size sedan is often the sweet spot: tanks in the trunk or one tank in the trunk and one on the rear floor, soft gear on the seat, and everyone still rides comfortably.
SUVs
An SUV helps when your gear is bulky or you want easy loading. The hatch opening and taller cargo area usually make tank placement simpler, and you’re less likely to have the “will this fit through the opening?” moment.
The trade-off is that wet gear and enclosed space can create that damp smell faster if you don’t air things out. If you go SUV, a simple habit like cracking windows when parked safely and not sealing wet neoprene in a closed bag goes a long way.
Pickups (standard and deluxe)
For many Bonaire divers, a pickup is the most practical choice. Tanks go in the bed, wet gear stays out of the cabin, and loading is quick. If you’re shore diving a lot and doing multiple stops in a day, the convenience adds up.
The trade-off is exposure. Anything in the bed is exposed to sun, salt air, and curious eyes when you’re parked. You’ll want a plan: keep valuables with you, use simple bins or gear bags to keep things from sliding, and avoid leaving anything you’d be unhappy to replace.
Specialty options (like classic 4x4s)
These can be great for comfort and capability if you’re exploring rougher areas along with diving. For tank transport specifically, the benefit is usually space and durability rather than “more fit.” If your itinerary includes Washington Slagbaai National Park plus dive gear, extra clearance and a rugged setup can feel worth it.
Smart ways to load scuba tanks so they don’t roll
Even when tanks fit, you want them stable. A rolling tank in the back seat is distracting at best and dangerous at worst.
The simplest method is to lay tanks flat and keep them from moving side-to-side. If you have two tanks, place them parallel with a small buffer between them so the valves are not knocking together. Soft items like towels or a BC can act as padding.
If tanks are in the trunk, use the trunk corners to your advantage. A tank that’s snug against the side wall is less likely to shift. In an SUV cargo area, placing tanks lengthwise and filling gaps with soft gear is usually more stable than leaving open space.
In a pickup bed, you’ll have the most room – which can also mean the most sliding. A couple of simple habits help: keep tanks grouped together, put heavier items low, and use a bin or a rubber mat if you have one to reduce movement. You do not need an elaborate setup to make it feel controlled.
What about sand, saltwater, and the interior
If you’re doing a week of shore diving, the mess is not hypothetical. You’ll have sand in your hair, on your feet, and in every seam of your gear bag.
If you’re renting a car with cloth seats and you know you’ll be wet often, bring a couple of lightweight towels to sit on and to wrap around dripping items. Keeping one “dry towel” separate from your dive towels makes the ride home a lot more comfortable.
Also, think about where wet items live between dives. A sealed trunk can trap moisture. A pickup bed keeps things airy, but bakes gear in the sun. An SUV gives you flexible space, but you’ll want to air it out.
None of these is a dealbreaker – it just changes what “easy” looks like for your group.
A quick decision guide for typical Bonaire trips
If you’re a couple doing one or two shore dives a day and traveling light, an economy car or small sedan can work. You’ll be loading tanks into the back seat more often, but it’s manageable.
If you’re two divers with lots of gear, or you want everything inside and not stacked on laps, a mid-size sedan or SUV tends to feel smoother day-to-day.
If you’re diving hard (multiple stops, wet gear, sandy feet, tanks every day) and you want the simplest loading routine, a pickup is hard to beat. It’s not about “can it fit” as much as “can we do this five days in a row and still enjoy it?”
If you’re unsure, tell the rental team what your group looks like and how many tanks you’ll typically carry. At Bonaire Rent a Car, we’re happy to help match you with a vehicle class that fits your diving plans, and you can book online at https://www.bonairerentacar.com.
Small but important safety and comfort notes
A tank valve can bump and scratch interior panels if it’s loose. Keeping valves pointed away from doors and using a towel as a buffer prevents annoying damage.
Try not to stack heavy gear high. If you have to brake quickly, that gear shifts forward. Keeping heavier items low and snug is the simplest safety move you can make.
And if you’re doing a longer drive between sites, crack a window for airflow when it’s safe. That small bit of ventilation helps with wet gear smell and keeps the cabin more comfortable.
You don’t need a perfect setup to have a great dive trip. You just need a vehicle that matches how you actually travel: the number of tanks you’ll carry, the number of people in the car, and your tolerance for wet gear inside the cabin. Choose for your real routine, and the rest of Bonaire gets a whole lot simpler.
