ABSTRACT OF THE DISCLOSURE A water vessel comprising a platform to support an operator, and flotation means to support the platform above water level, and a viewer to allow the operator to look both underwater and ahead above the waterline. The viewer comprises a curved visor, part of which is submerged below the waterline and part of which is above the waterline, a housing to support the visor, a hood to shield the visor from ambient light and glare, and a viewing port through which the operator may observe both the underwater environment and the surface environment ahead. The vessel may be operated by a joy stick which controls two motor driven propellers mounted on each side of the platform below the waterline and are protected by a tubular housing and front and rear guards. Ideally, an improved visor is enclosed and substantially sealed to keep out sea water, rain water, dirt, etc., and to avoid fogging of the visor a desiccant is provided with ports to allow air in and out to equalize and relieve pressure.
