Samurai comes from saburau — an old Japanese verb meaning to protect. The ship was built to earn the name.
In ordinary times she works Tokyo's canals as a sightseeing and environmental-education vessel. She was designed so that, in a disaster, her long-running generators could power medical equipment, provide flushing toilets, charge phones and move people and supplies.
Two diesel generators drive two electric motors. Against a conventional diesel hull the difference is immediate: very little vibration and very little sound.
The catamaran hull suppresses roll, which matters for guests who don't love boats, for children and for older travellers. Conversation carries. Music stays clean. Cameras stay steady. That is what the ship is actually for.
No roof, no pillars. Fireworks bloom directly overhead — a freedom no window-lined cruiser can offer.

What you hear is the water and the conversation. Toasts and music are not drowned out by engine noise or vibration.

A catamaran hull resists roll better than a typical single-hull boat — the choice for anyone who worries about seasickness. Some motion may occur depending on sea conditions.

Far from standard on a boat this size. Hours on the water, zero worries.
