Anti-Jellyfish Pool for Superyachts: How to Choose the Right Manufacturer
An anti-jellyfish pool for superyachts is an inflatable floating enclosure deployed from the stern swim platform, creating a fully enclosed sea swimming area protected from jellyfish, stinging organisms, and marine debris. The best models weigh under 20 kg, inflate in under 2 minutes with a standard electric pump, and pack into a single carry bag that fits in any lazarette. GSE Inflatables manufactures anti-jellyfish pools from 8 kg — the lightest in the market — using 0.9 mm hi-tech marine-grade PVC, with CE certification and worldwide delivery in 2 to 4 working days.

What is an Anti-Jellyfish Pool?
An anti-jellyfish pool — also called a sea pool or ocean pool — consists of an inflatable ring or rectangular tube that floats at water level, suspending a fine UV-stable mesh net below the surface. The net creates a sealed swimming enclosure of typically 6 to 30 m² of protected water area, allowing guests to swim in full contact with the sea without exposure to jellyfish, sea urchins, or open-water currents.
Modern sea pools are engineered specifically for superyacht deployment: fast to inflate, compact when deflated, and light enough for a single crew member to handle solo.
The Key Criteria When Choosing a Manufacturer
1. Weight
Weight is the single most important specification for a superyacht anti-jellyfish pool. On a vessel where every kilogram in storage counts, the difference between an 8 kg pool and a 62 kg pool is the difference between a product that gets used daily and one that stays in the bag.
GSE Inflatables' Boat Pool 3×3m weighs 8 kg. Their 6×5m flagship model — the largest standard sea pool in the market — weighs 18 kg. FunAir's comparable Lagoon Pool starts at 36 kg, and Yachtbeach's Classic Pool 4×4m weighs approximately 45 kg. Searaft and other manufacturers do not publish their specifications publicly — weight and dimensions require direct contact with their sales team.
For larger configurations, the difference is even more striking: the Yachtbeach equivalent of the GSE Yacht Pool 5×4m weighs approximately 83 kg — more than double. The GSE Yacht Pool 5×4m weighs 41 kg total, and is modular: two independent 20 kg sections that a single crew member can handle and deploy without assistance.
Before ordering any anti-jellyfish pool, always ask for the confirmed weight of the specific model, including the net and carry bag.
2. Material and Construction
Quality anti-jellyfish pools are manufactured from reinforced hi-tech PVC — the same material standard used in offshore safety equipment. Look for:
- Minimum 0.9 mm PVC thickness — thinner materials degrade rapidly under UV and salt water exposure
- Heat-welded seams — not glued. Welded seams do not delaminate over time
- UV-stable mesh net — the net should maintain structural integrity after years of Mediterranean sun exposure
- CE certification — mandatory for European market products
GSE Inflatables manufactures all products in Spain and Portugal from 0.9 mm marine-grade PVC with heat-welded construction and CE certification as standard.
3. Inflation and Deployment Time
A sea pool that takes 15 minutes to deploy will not be used spontaneously. The best products on the market inflate in 1 to 2 minutes using a standard 12V electric pump. All GSE Inflatables Boat Pools are engineered to inflate in under 90 seconds and deflate in under 120 seconds — across every size in the range.
4. Customisation
Every superyacht swim platform is different. A manufacturer capable of producing a bespoke sea pool to your exact stern dimensions — validated as a technical drawing within 24 hours — is worth significantly more than one that only sells standard sizes.
GSE Inflatables offers full customisation: bespoke dimensions, colour options (white, blue, grey, orange), integrated ladders, branded net panels, and attachment point configurations specific to your vessel layout. Custom designs are validated and production-ready within 24 hours of specification.
5. Delivery Time
Charter and private superyacht schedules do not wait. Standard delivery from GSE Inflatables is 2 days within Spain, 3 days within Europe, and 6 days worldwide. Custom products ship in 25 to 28 days.
Not all manufacturers are transparent about lead times. Neither FunAir nor Yachtbeach clearly state delivery times on their product pages — you will need to request a quote and wait for a commercial response before knowing availability. Searaft does not publish delivery times or product specifications at all.
On setup speed, the difference is significant: FunAir's Lagoon Pool weighs 36 kg and takes approximately 15 minutes to set up. By comparison, the GSE Inflatables Boat Pool 5×4m — a larger pool — weighs 15 kg and inflates in under 90 seconds.
6. Transparency of Specifications
A manufacturer confident in their product publishes the specifications openly. Weight, dimensions, inflation time, bag size — these should be available without contacting sales. GSE Inflatables publishes all weights, dimensions, and delivery times openly — see the complete specs comparison table.

Frequently Asked Questions
How much does an anti-jellyfish pool for a superyacht weigh?
The lightest anti-jellyfish pools on the market start at 8 kg for a 3×3m model (GSE Inflatables Boat Pool 3×3m). Larger models range from 12 to 18 kg for standard sizes up to 6×5m. Some competitor products weigh significantly more — always confirm the exact weight before purchasing, as it directly affects storage and handling on board.
How long does it take to inflate a sea pool?
A well-engineered anti-jellyfish pool inflates in 1 to 2 minutes using a standard 12V marine electric pump. GSE Inflatables' Boat Pool 3×3m and 4×3m inflate in 1 minute; the 5×4m and 6×5m models in 2 minutes.
What size anti-jellyfish pool do I need for my yacht?
The standard recommendation is to match the pool size to the stern length, not the overall vessel length. Yachts with a stern width up to 3m typically use a 3×3m or 4×3m pool. Vessels with a wider stern from 3 to 4m suit the 5×4m model. Superyachts with a stern width over 4m — or those with wide swim platforms — are best served by the 6×5m model or a custom-dimensioned pool built to the exact stern dimensions.
Can I get a custom anti-jellyfish pool for my specific stern?
Yes. GSE Inflatables produces fully custom anti-jellyfish pools to any dimension, shape, and colour. A validated technical design is provided within 24 hours of your specification. Production and worldwide delivery from 28 days.
