Abstract: A pair of wide angle mirrors and mirror assemblies adapted to be mounted on the bow or bowrail of a large sailboat comprised of a pair of mirror brackets for use in fixing the mirrors to the bow or the bowrail of a sailboat, a pair of mirrors, means for mounting one of said mirrors so as to permit pivotal movement about a horizontal axis to each of said mounting brackets and means attached to each of said mirrors so that each mirror will maintain the reflecting surface thereof in a vertical plane without regard to the plane of the deck of the large sailboat, said assemblies, when attached to the bow or bowrail of a large sailboat, permitting the helmsman to see portions of the horizon forward, around, and behind the sails which, in the absence of this invention would be obscured by opaque sail material and further preventing dangerous impacts with other sailing or mechanized craft and with stationary object whose presence could not otherwise be detected by the helmsman prior to the initiation of any maneuver
