If your father is osmeone who loves to cruise, you'll find several interesting things to choose from for him at CruiseReady on Zazzle Here are a few of them:
First, how about a embroidered with an "Official Cruiser" polo shirt, complete with a little embroidered cruise ship, and personalized with his name? Shown here in white, it also comes in red or blue.
Here's something a little different for the cruising Dad (or GrandDad) who also happens to be a grillmaster. He'll love barbequeing in this "I'd Rather Be Cruising" apron. Available in long or short lengths.
