A boat cover assembly utilizes a windshield bottom trim element which mounts a
boat windshield to also mount a boat cover or canopy. The windshield bottom trim
element comprises an upper portion defining a windshield receiving channel, a bottom
portion having a generally convex outer lower surface. a substantially hollow interior,
and a side access opening, and a middle portion comprising a fastener-receiving
side opening. A number of different types of fasteners may be received within the
fastener-receiving side opening, each connected, or connectable, to a fabric (such
as canvas) which can cover the windshield, and also serve as a boat top. The fastener
may have a substantially flat first face, a second face having a stem, and first
and second flexible projections extending outwardly from the stem, and fabric substantially
permanently attached to the elongated body by stitching. The flexible projections
may be received by undercut recesses at the access to the fastener-receiving side opening.
