If you're not a party enthusiast, consider our 4-Cup Holder. If you are, read on! The Party Barge secures to horizontal surfaces, preventing bottles and cups from falling. It features five deep 3.5" cup holders accommodating cans, bottles, and glasses. Each slot fits our Small Dry Box, keeping drink essentials fresh. A raised ring tops it, corralling limes. The center bottle hole fits a 2-liter mixer bottle, while two outer holes, approx. 5 1/8" in diameter, fit 1.75-liter bottles. Adjustable arms with locking knobs secure smaller bottles. At approx. 22.5" x 16", it's made from 3/4" white Starboard and comes with a 6" SeaSucker for strong hold. Choose between black or white, and round or square holes.
