Rayka Design Studio is working on a hydrogen-fueled passenger boat that offers speed without emitting toxic gases. Inspired by dolphins, the Hydro Dolphin allows passengers to sit in different positions and can be used in still waters like the Golden Horn.

The 22m long boat carries wide glass facades that can be easily be moved depending on the weather conditions. The glass design enables passengers to enjoy a view of the sea from all angles, provided the weather holds up sunny. Inside the boat, there is space for the installation of a small kitchen unit or a stand depending on the requirement of the owner and its use.
