Identifying a painting?

Could the signature be saying Collins?

With one "l". Maybe.

That's a yawl-rigged sloop, about 70 to 90 feet at the load water line. Perhaps you could do an image search with the artist's name and "sloop," or "yawl," and see what comes up.

I just did a quick image search (i'm not going to spend a lot of time on this), and i did not find your image. If you can be more certain of the artist's name, though, it might work. A yawl is a sloop with the small mast at the back, and the large mast at the front. I didn't find your image, but most of the images google offered were images of yawls. (I'm not convinced about the name.)
