A 4-person rubber boat made by Joycraft is equipped with a 6 horsepower outboard motor. The hull has a 4-chamber structure, so even if there is an air leak, the boat will not sink. The seat is about 15 cm above the water surface. Looking up at the townscape from a perspective that feels like you are floating just above the water is a refreshing experience.
The speed is about jogging speed. There are no toilets or roofs, and waves sometimes crash into the boat. It's not as comfortable as other cruise ships, but you can enjoy a wild and adventurous walk on the water that only a rubber boat can offer.
