The anti-jellyfish pool for boats has become one of the most sought-after accessories in the luxury yachting sector. If you spend your holidays on a boat and want to swim in safe water, protected from jellyfish, fish and debris, an inflatable pool for boats is the ideal solution. In this complete guide you'll discover how it works, which models exist and how to choose the right one for your yacht.
What is an anti-jellyfish pool for boats?
An anti-jellyfish pool — also called a sea pool or floating pool for yachts — is an inflatable pool that attaches to the stern of the yacht and partially submerges in water, creating a swimming environment isolated from the open sea. The net or waterproof PVC structure prevents jellyfish, fish and any external elements from entering, guaranteeing a clean and safe swimming experience directly from the boat.
Unlike a rigid pool, the inflatable version inflates in 1-2 minutes, deflates in the same time and folds into a compact bag. For a yacht where space and weight are critical factors, this advantage is decisive.
Why install an anti-jellyfish pool on your yacht?
The Mediterranean and tropical waters frequented by luxury yachts are often infested with jellyfish, especially during summer months. Contact with a jellyfish can ruin a holiday — or worse, cause severe allergic reactions. The anti-jellyfish pool completely eliminates this risk, offering your guests a safe space to swim in any marine conditions.
- Total protection: no jellyfish, fish or debris can enter the pool.
- Safety for children: younger guests can swim freely without risk, in a delimited and controlled area.
- Guaranteed comfort: the water in the pool stays clean throughout the swimming session.
- Use in any destination: from the Mediterranean to the Caribbean, it works everywhere regardless of local marine conditions.
- Quick setup: inflation in 1-2 minutes, deflation in 2-3 minutes.
Types of inflatable pools for boats
There are two main families of inflatable pools for yachts, each with different characteristics and price ranges:
Boat Pool: the pool for medium-sized boats
The Boat Pool is the most versatile solution, available in four standard sizes:
- Boat Pool 3×3 metres — ideal for yachts from 12 to 20 metres. Spacious, easy to handle, perfect for families.
- Boat Pool 4×3 metres — the best-selling size. Excellent balance between capacity and storage practicality.
- Boat Pool 5×4 metres — for yachts from 25 metres upwards. Enough space to swim comfortably.
- Boat Pool 6×5 metres — the largest version of the standard range. For maxi yachts and superyachts.
Yacht Pool: the anti-jellyfish pool for superyachts
The Yacht Pool 5×4 metres is our flagship product. Designed specifically for superyachts of 30 metres and above, it offers a generous swimming space, premium marine-grade materials and high-quality finishes that integrate perfectly with the aesthetics of a luxury yacht.
For those with special requirements — custom dimensions, specific colours, or special configurations — we also offer the Custom Yacht Pool, designed and produced to measure for your vessel.
How an anti-jellyfish pool works: the technology behind the product
The operating principle is simple but ingenious. The pool consists of an inflatable perimeter structure that floats on the water surface and a waterproof or fine-mesh base that forms the submerged bottom and side walls. Once inflated and anchored to the stern of the yacht, the structure creates a closed enclosure that physically prevents any marine element from entering.
The materials used are marine-grade PVC with anti-UV treatment and salt resistance, guaranteeing a lifespan of 5-10 seasons of intensive use. The seams are heat-welded with reinforced double-stitch technology, the same system used in professional inflatable boats.
How to choose the right anti-jellyfish pool for your boat
Choosing the right model depends on three main factors:
Yacht size
The pool anchors to the stern, so the dimensions of the transom determine the maximum usable size. As a general rule:
- Yacht 10-20 m → Boat Pool 3×3 or 4×3 metres
- Yacht 20-35 m → Boat Pool 4×3 or 5×4 metres
- Superyacht 35 m+ → Yacht Pool 5×4 or Custom Yacht Pool
Number of guests
A Boat Pool 3×3 is comfortable for 2-4 people at a time. For large families or charters with many guests, the 5×4 or larger version guarantees adequate space without compromising comfort.
Frequency of use
For intensive use in professional charters, we recommend the Yacht Pool or Custom Yacht Pool, designed to withstand daily use throughout the season. For more occasional private use, the standard Boat Pools offer excellent value for money.
Installation and maintenance: simpler than you think
One of the most frequent questions is: how difficult is it to install an anti-jellyfish pool? The answer is: much less than it seems. The standard process followed by professional crews is as follows:
- Remove the pool from the storage bag and spread it on the stern platform.
- Connect the electric pump to the main valve and inflate — an operation that takes 60-90 seconds.
- Lower the pool into the water from the stern using the included anchor cables.
- Secure the fixing straps to the handrails or deck cleats.
- Check the seal and absence of debris before guest use.
For maintenance, simply rinse with fresh water after each use, fully deflate before storage and store in a dry, shaded location. With these simple precautions, the pool will maintain its characteristics for many seasons.
Recommended combinations: create the perfect setup for your yacht
The anti-jellyfish pool works even better when combined with other nautical accessories. Our most satisfied customers often combine:
- Pool + Boat slide: the slide is positioned above the pool; guests slide directly into the protected space. A perfect combination for families with children.
- Pool + Inflatable platform: the platform creates a staging area around the pool, making water access easier for guests of all ages.
- Complete Pool + Platform set: discover our combined sets catalogue for complete packages at advantageous prices.

Frequently asked questions about the anti-jellyfish pool
Does the anti-jellyfish pool work with current or wave motion?
Yes, but with some limitations. With moderate current (up to 1 knot) and reduced wave motion, the pool maintains its shape and function. In rough sea conditions or strong currents, we recommend not using the pool for safety reasons. Anchoring in protected bays is always the best choice.
How many people can use the pool at the same time?
It depends on the model. The Boat Pool 3×3 is comfortable for 2-4 people; the 4×3 for 3-5 people; the 5×4 and Yacht Pool for 5-8 people. These are guidelines for comfortable use; the structure can support higher loads without structural issues.
Can I use the pool in fresh water (lakes, rivers)?
Absolutely yes. The pool works perfectly in fresh water too, although the jellyfish protection is obviously only relevant at sea. In fresh water, the main advantage is creating a delimited and safe swimming area for children.
