I saw this knot on a card made by mnfroggie on Splitcoaststampers. Here is the Link on Trina's blog for her tutorial on how to make the knot. The sticker in my card is from Karen Foster Designs. The map was simply torn out of a map book and inked up. The anchor, wheel and lifebouy were recycled from a miniature ship that had seen better days. Note: a little boy may promise not to break a decorative ship, but that doesn't mean it won't get beat up! lol
Here's another masculine card I made by layering a map on kraft cardstock, inking it up and adding more Karen Foster Design stickers. I think it looks like the stickers were always meant to be there.
