I claim, the ornamental design for a cover for pontoon boat, as shown and described.
FIG. 1 is a perspective view of a cover for a pontoon boat, showing our new design;
FIG. 2 is a front view of FIG. 1;
FIG. 3 is a back view of FIG. 1;
FIG. 4 is a side view of FIG. 1;
FIG. 5 is another side view FIG. 1;
FIG. 6 is a top plan view of FIG. 1; and,
FIG. 7 is a bottom view of FIG. 1.
The broken lines represent portions of the cover and the exemplary environment of a pontoon boat that form no part of the claimed design.
Also, references to “side,” “top,” “bottom,” “front,” and “back” in the Figure Descriptions are not necessarily meant to require any specific orientation of the article as viewed.
