Inflatable yacht slides: sizes, mounting, prices and the standards that apply

An inflatable yacht slide is sized by the drop from the rail to the waterline: standard models run from about 1.5 metres to 8 metres, with custom builds above 12 metres. Published prices start at £3,500 excluding VAT for a 3-metre slide. ISO 25649-6 names inflatable slides as a typical Class D product, but whether it covers rail-mounted slides is not settled.

Product figures are the manufacturers' own, checked on 4 October 2026; no page gave a date. Prices are not converted, and the tax basis is shown for each.

What size of slide does a yacht need?

The size depends on the height from the rail to the waterline, not on the yacht's length. FunAir: "The right size depends on your rail-to-waterline drop" (FunAir FAQ). AquaBanas measures from the top of the handrail; its side arms add 127 cm to the overall height (AquaBanas).

Superyacht Inflatables (documented only via the retailer Superyacht Marine Store) offers 3 to 8 metres as standard, with a rule of thumb: 4.4 m rail height takes a 4 m slide, 5.0 m a 5 m and 5.6 m a 6 m slide (Superyacht Marine Store). Yachtbeach sells its Magic Yachtslide for rail heights from 270–350 cm up to 700–780 cm (Yachtbeach). FunAir ranges from 1.5 m (FunSize, for yachts up to 20 m) to custom slides over 12 m (FunAir FAQ).

How heavy are yacht slides and how long does set-up take?

From about 20 kg to 300 kg, according to the manufacturers:

FunAir contradicts itself on the Hanger Extreme: the product page gives about 254 kg for an 8.4 m slide, the data sheet 140–220 kg (FunAir).

For a 5 m slide, FunAir quotes about 15 minutes to inflate, 30 for the full set-up and 45 to deflate and pack (FunAir FAQ).

How is a slide fixed to the yacht?

Most slides hang over the rail, secured with lines or straps. FunAir's Fun Slide "hooks over the rail on your yacht and has lines to secure placement" (FunAir blog). According to FunAir, its slides sit 10–15 cm above the rails without putting load on them, and attachment points and rigging are defined during design (FunAir FAQ). The Riser adds a detachable inflatable support leg (FunAir).

Yachtbeach fixes its slides with D-rings and straps and uses four air chambers plus a pressure-relief valve (Yachtbeach). AquaBanas lists several anchor and lifting points and a built-in sprinkler (AquaBanas). Superyacht Inflatables includes a lifting harness, electric pump and repair kit with its 5 m slide (Superyacht Marine Store).

FunAir names 1000-denier PVC with fire-retardant and UV ratings, 316 stainless fittings and side netting (FunAir), and five years' warranty on custom yacht products, 90 days on pumps (FunAir FAQ).

What do yacht slides cost?

FunAir and AquaBanas showed no prices on the pages checked.

Superyacht Inflatables appears only on the retailer's site; whether it is the retailer's own brand is unclear. The Aquaglide slides are not fixed to the yacht: they float on their own and are anchored.

How many people and how much weight can a slide take?

None of the yacht-slide makers we checked publishes a maximum number of users or a maximum load. FunAir says "weight capacities vary depending on the specific design and purpose of the product" (FunAir FAQ).

Only the free-floating Aquaglide slides have published limits. The Freefall 6 takes three adults or three children, up to 272 kg, and needs at least 1.8 m of water, 500 kg of anchor weight and 3 m clearance from the shore (Aquaglide). The Velocity Slide 10.0 takes four people and needs 7.8 feet of water (Aquaglide).

Which standards apply to inflatable yacht slides?

The relevant family is ISO 25649 for floating leisure articles, but we found no official statement that it covers slides hung from a yacht's rail. ISO 25649-1:2024 sets general safety requirements and tests for floating leisure articles used on and in water (ISO). It replaces the withdrawn 2017 edition and applies only together with Part 2 (consumer information) and the relevant class part (ISO; SIS, 2017 edition).

ISO 25649-6:2024 adds requirements for Class D devices and lists "inflatable slides" as a typical Class D product (ISO). Its typical locations include the open sea, and the sea shore only with "no offshore winds, no currents" (ISO). In the class table of the draft standard (ISO/FDIS 25649-1, 2024), Class D articles are meant for active use, have no means of propulsion and "shall be anchored" (ISO/FDIS 25649-1 sample). We saw this table only in the draft.

ISO 25649-1 does not apply to "devices that are kept in shape by permanent air flow", so a slide that needs a running blower is outside it (ISO). The bouncy-castle standard EN 14960-1 is for inflatable play equipment for children aged 14 and under and "is not applicable to inflatable water-borne play and leisure equipment" (SIS).

Does the flag state regulate yacht slides?

We found no flag-state rule on slides. The REG Yacht Code only refers jet-ski operation to coastal-state law and has no rule for slides (REG Yacht Code, Annex G7). For local water-toy rules in one region, see jet skis and water toys in the Balearics.
