Yes. It should be an AMF Alcot Sunfish with removable center board. Flotation vest and the Sunfish will provide you with fun learning to tack . . .
Been thirty or more years since I used one and eventually moved to an antique wooden peapod hull sailing vessel. At times I missed the maintenance freedom (teak, mahogany and light oak require too much work) of the Alcot . . . I think.
I digress . . . the Sunfish was used for several years in sailing races and was so popular for this venue it replaced several other small sailers. You should have fun in a stiff wind.
