Project E12 modification - Water Taxi - is a catamaran designed for passenger transportation, sightseeing tours, and crew shifts delivery to remote areas. The cabin is configured for 24 passenger seats.

The design concepts for the water taxi and the corporate catamaran were developed by the Sea Tech Design Studio (2007) based on sketches by Mr. S.V. Skardov, as potential evolutionary variants of the baseline Project E12 (Elan catamaran).

Water taxi layout:

24 passenger seats, dedicated operator's station, toilet, wardrobe, luggage shelves, and a cabinet for an electric water boiler. Bow, stern, and side exits. A folding bow ramp is provided for shore landing.
