A fuel cell ship includes a fuel cell compartment in which a fuel cell is installed, a tank compartment in which a fuel tank is installed, a fuel supply pipe through which fuel is supplied from the fuel tank to the fuel cell, and a control unit. The fuel supply pipe includes at least two shutoff valves. Fuel gas detectors that detect a fuel gas being in a gaseous state of the fuel are each installed in the compartments. If at least one of the fuel gas detectors detects that a concentration of the fuel gas is equal to or greater than a predetermined standard value, the control unit controls to close a shutoff valve in a compartment out of the tank compartment and the fuel cell compartment, where the fuel gas detector having detected the concentration equal to or greater than the standard value is installed.

An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied by a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes at least one compartment including an emission source of the fuel, and a vent pipe through which the fuel in the compartment is released to outside of the hull. A release port of the vent pipe is located at a position higher than a cabin or a bridge provided on the hull.

A fuel cell ship includes a storage battery compartment installed with a storage battery that supplies, to a propulsion device, electric power different from electric power by a fuel cell. The storage battery compartment is provided between a deck and a ship bottom portion of a hull.

An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied from a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes a tank compartment installed therein with a fuel tank that stores the fuel. The tank compartment is provided below a deck of the hull and provided separately from other compartments.

An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied from a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes a plurality of compartments including an emission source of the fuel, in which the plurality of compartments include a tank compartment installed therein with a fuel tank that stores the fuel and a fuel cell compartment installed therein with the fuel cell. The tank compartment and the fuel cell compartment are each sealed except for a ventilation port through which the inside of the compartment is ventilated.

A superstructure-integrated backspray mitigation system for yachts including an aft spoiler secured to the vessels hardtop for directing airflow about the hardtop downwardly into the aft cockpit area to interfere with, mitigate and eliminate the natural reverse backspray created by the low-pressure region behind the yacht. The spoiler protrudes from the hardtop and includes at least one air ducting channel directing airflow at select angles into the cockpit area presenting a protective shield preventing the backspray from entering the cockpit. An optional pivotal panel member selectively enables operation of the spoiler.

There is described a ventilation system for a boat. The windshield body comprises an air scoop in a bottom portion of the windshield body, facing a forward direction of the boat for air entry, the air scoop having an entry which is substantially horizontal and the air scoop extending upwardly within the windshield body to form a conduit having an upward component. The conduit end opens toward an inside of the boat, at a location higher than the entry of the air scoop. A hingeable vent can be installed on the opening inside the boat to be open or closed. The vent may also be sued with a direct opening with the outside. In this case, flaps can be installed in the opening. The flaps can be hingeable about their own respective hinge axis, and move together using a solid link. The flaps may be used without the vent.

Fabric air shaft ventilator with instant opening and fastening for boats.

The invention relates to a device for improving air circulation on board boats.

It consists of a frustoconical-shaped fabric (8) whose air inlet (1) is maintained in position by two rods (2) and (4) maintained in the form of loops in contact with the deck of the boat and whose air outlet (3) is positioned inside the deck hatch.

The device can be oriented in all directions and does not require anchoring at height, so that it can be used on all deck hatches of sailboats and motorboats.

The rod (1) is folded in a figure of eight so as to occupy less space when it is not in use.

The device according to the invention is particularly intended to improve comfort on board boats by improving air circulation.
