This Docktail pontoon caddy solves that classic problem of never having enough cup holders where you actually need them on your boat! It's specifically designed to clamp onto 1¼ inch pontoon rails - no tools or hardware needed, just twist the locking knobs and you're ready to party. The caddy holds four drinks securely, accommodating everything from 12oz cans and bottles to larger tumblers like Yeti, Tervis, and Ozark Trail up to 30 ounces. But wait, there's more - the enclosed center section gives you perfect storage for phones, sunglasses, sunscreen, and other small items that always seem to disappear on the water. The drainage holes mean any spilled drinks or water won't pool up. Made from 3/8 inch King Starboard with stainless steel fasteners, this thing is built to handle the marine environment without rusting or deteriorating. Measuring 18x5x7 inches and weighing 5 pounds, it's substantial enough to stay put but not overly bulky. Perfect for mounting near boarding doors, on ladder rails, or anywhere you and your guests tend to congregate. The weatherproof construction means you can leave it on your pontoon all season without worrying about damage. It's one of those simple boat accessories that you'll wonder how you ever managed without once you have it installed!
