Inflatable Platforms vs. Fixed Swim Platforms: Which Is Better for Your Boat?

Almost every modern motor yacht and catamaran comes with a fixed bathing platform at the stern — a moulded fibreglass step at water level, typically 60 to 120 cm deep. It is useful, but it has clear limits. An increasing number of boat owners are adding inflatable platforms to dramatically extend their usable water-level space. Here is how the two options compare across every dimension that matters.

Space: No Contest

A typical fixed platform gives you 0.5 to 1.2 square metres of usable space — enough to rinse a mask, board a tender, or help someone exit the water. It is not a place you sit, sunbathe, or gather as a group.

An inflatable platform gives you 6 to 10 square metres of floating deck space attached directly to your stern. Available in 3×2m, 4×2m, and 5×2m sizes, they turn your stern into a proper floating terrace. On that space, you can sunbathe, eat lunch, let children play safely at water level, or use it as a launch pad for paddleboards and snorkellers.

Versatility

A fixed platform is always there — and always the same size. You cannot remove it when docked in a tight marina berth, and you cannot make it larger when you have more guests on board.

An inflatable platform deploys when you need it and packs away when you do not. It can be used independently as a sun deck, or combined with an anti-jellyfish pool to create a complete floating leisure area. Our pool and platform sets bundle both products together at a combined price — giving you a jellyfish-protected swimming pool on one side and a generous floating terrace on the other.

Safety for Children

Fixed platforms sit right at water level with no sides or railings. Children can easily slip off into open water. An inflatable platform has raised tube sides that act as a natural barrier, making it significantly safer for young children and non-swimmers. The EVA teak surface available on some models is also non-slip when wet — important when wet feet are everywhere.

Cost

Fixed platforms come with the boat — they cost nothing additional, but they also cannot be upgraded without a refit. A quality inflatable platform starts at around €1,210 and represents a one-time purchase that lasts many seasons with proper care and storage.

Compare that to a yard refit to extend or modify a fixed bathing platform — fibreglass work, paint, antifouling — which can cost several thousand euros. The inflatable option is cheaper, removable, and does not affect your boat's resale value.

What About Purpose-Built Inflatable Docks?

For jet ski, Seabob, or e-foil owners, our range of inflatable docks are shaped specifically for each water toy, making boarding and exit safer and easier than from a fixed platform. They store flat when not in use and deploy in minutes — a practical upgrade any water toy owner will appreciate.

The Verdict

A fixed platform is a convenience. An inflatable platform is a transformation. If you spend meaningful time at anchor — whether in Mallorca, the Adriatic, the Turkish coast, or anywhere else in the Mediterranean — adding an inflatable platform is one of the highest-value upgrades available for how your boat is actually used on the water.
