Superyacht Inflatable Glossary

An anti-jellyfish pool (also called a sea pool or ocean pool) is an inflatable floating enclosure deployed from the stern swim platform of a superyacht. It creates a fully enclosed swimming area that keeps out jellyfish, sea lice, stinging organisms, and marine debris while allowing guests to swim in natural open water.

The best models weigh between 10 and 20 kg, inflate in under 90 seconds with a standard electric pump, and pack into a single carry bag for easy storage. Construction uses double-coated 0.9 mm marine-grade PVC with drop-stitch panels for stability.

Pool size should match the yacht's stern width: a 3 × 3 m pool suits yachts up to 10 m, while a 5 × 4 m modular pool is standard for superyachts above 30 m.

A modular yacht pool is an anti-jellyfish pool built in two or more independent inflatable modules that connect together on the water to form a single large swimming enclosure. Each module can be handled by one person, making deployment practical without crew assistance.

The GSE Inflatables Yacht Pool 5 × 4 m consists of two 20 kg modules — compared to equivalent single-piece pools from other manufacturers that can weigh 83 kg or more. The modular design also allows the pool to be configured in different shapes depending on the stern layout.

The Boat Pool 3 × 3 m is an entry-level anti-jellyfish pool designed for mid-size yachts up to 12 metres. At under 8 kg, it is the lightest inflatable sea pool in its class and can be set up by a single crew member in under 90 seconds.

It uses the same 0.9 mm marine-grade PVC construction as larger pools, meaning durability is not compromised by the smaller size. The compact deflated package fits in overhead lockers or tender garages.

An inflatable dock is a floating pontoon made from reinforced PVC or drop-stitch material, designed to provide a stable boarding, launching, or storage platform alongside a superyacht. Unlike rigid aluminium docks, inflatable docks can be deflated and stowed when not in use, making them ideal for vessels with limited deck space.

Superyacht inflatable docks are typically rated for loads of 200–400 kg and are used to launch and retrieve water toys including eFoils, Seabobs, kayaks, paddleboards, and jet skis.

An eFoil dock or jet ski dock is an inflatable floating platform that sits alongside the superyacht and provides a dedicated parking space for water toys such as eFoils, jet skis, and personal watercraft. Instead of lifting the toy back on board after each use, guests and crew can leave it docked on the platform — ready to ride again in seconds.

Beyond convenience, the dock acts as a protective buffer between the water toy and the yacht hull, preventing scratches and impact damage during mooring. GSE Inflatables docks use drop-stitch PVC construction for the rigidity and load capacity needed to hold powered watercraft safely at the water line.

A Seabob dock is a compact inflatable floating cradle designed to hold and launch a Seabob underwater scooter from the water's surface without bringing it onto the main deck. The dock keeps the Seabob buoyant and accessible at water level, protecting the hull from contact with the yacht's swim platform.

Because Seabobs weigh between 30–35 kg, a dedicated dock eliminates the need for crew to lift and carry the device repeatedly during a charter day.

A superyacht inflatable platform is a large floating surface deployed from the stern or alongside the yacht to extend the usable deck space onto the water. Platforms are used for sunbathing, yoga, beach club setups and water toy launching.

High-quality platforms use drop-stitch construction for a stable, non-bouncing surface and are rated for multiple adults standing simultaneously. They connect to the yacht via stainless D-Rings, adjustable lines or Velcro attachment.

An inflatable swim platform is a buoyant, rigid-surface deck deployed at water level from a superyacht or motor yacht, primarily used for swimming access, snorkelling preparation, and guest embarkation from tenders. Unlike fixed GRP or teak swim platforms built into the hull, inflatable swim platforms can be stowed below decks and deployed only when needed.

They are particularly useful when anchored in locations where the fixed swim step is too high above water, or where the yacht swings with tide and needs a stable water-level access point.

A tender platform is an inflatable floating dock used to moor the yacht's tender (RIB or jet tender) alongside the superyacht at anchor, keeping it accessible without requiring it to be hoisted back onto davits between uses. The platform floats at water level and features cleats or D-rings for securing the tender bow and stern lines.

Tender platforms reduce crew workload significantly on charter yachts where the tender is in constant use throughout the day.

A boat slide (also called a yacht slide or superyacht water slide) is an inflatable structure that mounts to the deck railing or upper deck of a yacht and extends over the side, allowing guests to slide directly into the sea. They are one of the most popular superyacht water toys for charter vessels.

Slides are rated by entry height (typically 2–6 metres above water), total length, and the number of simultaneous users. High-quality superyacht slides use heavy-duty 0.9 mm PVC.

A beach club inflatable is a large modular floating structure that transforms a superyacht's stern into a water-level beach club environment. It typically combines a wide flat platform (for lounging and dining), one or more anti-jellyfish pool enclosures, and docking sections for water toys — all inflatable and deployable within 15–30 minutes by the crew.

Beach club inflatables are bespoke in most cases, designed to match the transom dimensions and deck hardware of a specific vessel. They are increasingly specified as part of the initial outfitting for new superyacht builds above 50 m.

Superyacht water toys is the collective term for inflatable and non-inflatable recreational equipment carried aboard large yachts for guest entertainment. The category includes anti-jellyfish pools, inflatable docks, water slides, climbing walls, sports courts, paddleboards, kayaks, jet skis, eFoils, Seabobs, and towable inflatables.

For charter yachts, the water toy inventory is a key differentiator in guest experience and a significant factor in charter pricing. Inflatable water toys (as distinct from rigid items) are preferred because they can be stowed compactly when not in use and add minimal weight to the vessel.

An inflatable gangway is a floating bridge structure that connects the superyacht's stern or side to a quayside, another vessel, or a floating dock when the fixed gangway cannot reach or when the yacht is at anchor. Constructed from reinforced PVC with a non-slip walking surface and safety handrails, inflatable gangways are significantly lighter and easier to store than aluminium equivalents.

They are rated for specific load capacities per metre and must be matched to the maximum tidal range expected at the vessel's operating locations.

Custom superyacht inflatables are bespoke inflatable products designed and manufactured to the specific dimensions, colour scheme, and technical requirements of an individual yacht. Unlike off-the-shelf products, custom inflatables are engineered to fit a particular transom width, comply with the vessel's deck hardware, match the teak or hull colour, and meet any flag-state certification requirements.

GSE Inflatables manufactures custom pools, docks, platforms, slides, and beach club systems. The typical lead time for a custom build is 6–10 weeks from approved technical drawing.

Drop-stitch technology is a construction method where two outer PVC fabric layers are connected by thousands of vertical polyester threads (the "stitching") woven between them. When inflated, the internal pressure pulls equally on all threads, creating an extremely rigid, flat panel — unlike conventional inflatables which form a rounded tube shape under pressure.

Drop-stitch construction allows inflatable platforms, docks, and pool panels to achieve rigidity comparable to rigid fibreglass at a fraction of the weight. It is the enabling technology behind modern superyacht inflatable platforms and pools that must support the weight of multiple people without flexing.

Inflation pressure for drop-stitch products is typically 0.2–0.3 bar (3–4.5 PSI), compared to 0.05–0.15 bar for conventional tube inflatables.

Marine-grade PVC refers to polyvinyl chloride fabric specially formulated and tested for sustained exposure to saltwater, UV radiation, ozone, and the mechanical stresses of marine use. For superyacht inflatables, the industry standard is double-coated PVC fabric with a minimum weight of 0.9 mm (approximately 900 g/m²).

Key properties required for marine-grade classification include: UV stabilisation to prevent colour fading and brittleness, resistance to salt crystallisation, thermal stability for high-temperature storage in tropical climates, and sufficient tensile strength to withstand repeated inflation and deflation cycles (minimum 5-year outdoor service life).

GSE Inflatables uses 0.9 mm double-coated marine-grade PVC across all product lines, with welded (not glued) seams for maximum pressure retention.

Inflate time is the time required to fully inflate an inflatable product from its packed state to deployment-ready condition using a standard electric pump. For superyacht inflatables, inflate time is a critical operational specification because products are typically deployed and retrieved multiple times per day during charter use.

GSE Inflatables Boat Pools are engineered to inflate in under 90 seconds and deflate in under 120 seconds. By comparison, some competing pool products require 10–15 minutes to set up. Over a 7-day charter with multiple daily deployments, the difference in crew time and guest waiting time is significant.

Inflate time is determined by total air volume divided by pump flow rate. Drop-stitch products require higher pressure but smaller total volume; tube-based products require lower pressure but can have much larger total volume.

A superyacht beach club refers to the stern section of a large yacht — typically on vessels of 45 m and above — that is designed to open up at water level and function as a social entertainment hub. On many modern superyachts, the beach club is a fixed architectural feature of the hull, incorporating fold-down platforms, waterjet propulsion systems, and integrated storage for water toys.

In the context of inflatable equipment, a superyacht beach club setup typically refers to the combination of inflatable platforms, anti-jellyfish pools, inflatable docks, and water slides deployed from the stern to create a floating leisure environment. This inflatable beach club configuration is available on yachts that do not have a factory-built beach club, effectively recreating the experience at anchor.

A bespoke yacht inflatable is any inflatable product manufactured to a unique specification for a specific vessel. The term "bespoke" distinguishes custom-built items from standard catalogue products. In practice, bespoke inflatables are required when a yacht's transom width, deck hardware spacing, or hull overhang does not match standard product dimensions.

The bespoke process typically involves the manufacturer visiting the vessel (or reviewing technical drawings) to take accurate measurements, followed by the production of a design proposal, client approval, and then manufacture. Colour matching to existing deck equipment and hull paint is standard in bespoke projects.

An inflatable tennis court for superyachts is a floating or deck-deployable playing surface that replicates the dimensions and playing characteristics of a standard tennis court in a format that can be deflated and stored aboard a large yacht. Designed for vessels of 80 m and above, these courts are manufactured from reinforced drop-stitch PVC panels with surface texture engineered to provide the correct ball bounce.

Court markings are integrated into the surface material rather than painted, ensuring durability under saltwater exposure and UV. Net posts are either permanent welded fittings or removable stainless steel inserts. Setup time for a deck-installed inflatable tennis court is typically 20–40 minutes for two crew members.

An inflatable football pitch for superyachts is a modular floating or deck-installed playing surface configured to five-a-side or futsal dimensions, with boundary walls, goal frames, and a synthetic turf-effect surface — all in inflatable format for stowage and deployment from a large yacht.

The pitch typically measures 20 × 12 m to 28 × 16 m, accommodating five players per side. Boundary walls prevent the ball from entering the water and provide a contained playing environment. All components deflate to a fraction of their deployed volume and are stored in carry bags in the tender garage or below-deck stowage.

An inflatable basketball court for superyachts is a half-court or full-court playing surface in drop-stitch PVC format, complete with integrated three-point line, key markings, and one or two inflatable backboard systems with polycarbonate or acrylic backboards. Half-court configurations (typically 14 × 9 m) are more common on superyachts due to deck space constraints.

The playing surface uses drop-stitch construction for the rigidity required for safe running and jumping. Backboard systems are engineered to absorb ball impact without toppling, using ballasted bases or deck attachment points.

An inflatable fitness platform or inflatable gym for superyachts is a rigid drop-stitch platform designed specifically for exercise and training use, with integrated attachment points for resistance bands, suspension trainers (TRX), yoga mat surfaces, and optional modular weight storage. Deployed from the stern at water level or on the sundeck, it allows guests and crew to exercise in open air without monopolising main deck space.

The platform surface uses a non-slip texture engineered for bare-foot exercise. Load ratings typically exceed 400 kg across the full surface. When not in use, the entire platform deflates and packs to the volume of a large suitcase.

A superyacht inflatable climbing wall is an inflatable structure with textured climbing holds, designed to be installed on the bow, foredeck, or alongside the yacht for recreational climbing and bouldering.

Inflatable climbing walls are typically 3–6 metres tall in the deployed configuration and feature multiple climbing routes at different difficulty levels. The base is attached to deck fittings to prevent toppling. Deflated weight is typically 40–90 kg depending on height.
