With the aim of promoting tourism on inland waters that offer untouched areas of nature, Serbia-based Salt & Water has designed a floating hotel with detachable catamaran apartments.

A central floating construction provides a reception area, restaurant, event hall, offices and a café, while pathways connect to the individual catamaran apartments. These units can then be separated from the dock and navigated, so guests can choose their own holiday spot.

Each apartment can accommodate up to four people, and contains a salon, a galley, a bathroom, a hall with storage space and a sleeping area.

Two separate outdoor areas – a flying bridge and a beach platform – offer the opportunity to relax, swim, dive, fish or sunbathe.

Salt & Water, a specialist in yacht design, said its main idea in creating the concept was to allow hotel guests to navigate waters at a very slow speed to enjoy uninterrupted views of the surrounding nature. The unusually-shaped catamarans therefore feature large windows in the front to provide optimum viewing opportunities.

Floating accommodation has become a hot topic in recent months, with several innovative aquatic projects hitting the headlines. These have included a solar-powered floating resort in the Maldives, concept drawings for a snowflake-shaped buoyant hotel in Norway, and Airbnb's floating guest house which recently turned heads on London's River Thames.
