Sears Gamefisher 14' Tri Hull Fiberglass Boat
The year is a sears gamefisher 5.0 hp model 225-587505? Looks to be as early as the 70's. You can look online for the little amount of information that you can find on this old particular model.

In 1969, Sears sold several aluminum boat models under the "Sears Roebuck" brand, including the "Gamefisher" line, which featured various sizes and configurations suitable for fishing and recreational use. Models included the 12-foot and 14-foot Gamefisher boats, designed for stability and durability. Sears also offered accessories and motors to complement these boats, catering to the needs of outdoor enthusiasts.

There are many web sites that offer boat covers. You can find some nice ones at CarCovers4Less.com. At this site they have polyester covers for a 12' Gamefisher for $59.99 up to polyester canvas at $109.99. It will all depend on what you are looking for and how much you want to spend.
