A hard shell cover hunting blind for a boat that may be left on while transporting the boat to the water. The shell has an open back that allows full visibility when moving. A camouflage covering is secured to a hoop in the back that can be quickly dropped down. Two large clamshell doors are placed in the front. The shell has a sliding door that opens up the sides of the blind. This provides easy access into and out of the boat as well as for placing decoys, etc. In addition, there is a curved top that is mounted on slides. This top can be pulled to either side to provide a full 360.degree. filed of vision and a large shooting port. No tools are needed to operate the system of doors or to remove and install the clamshell front pieces.
