"Where can you put a drink while sailing on a small boat, that it is easily accessible, won't roll overboard, or get all nasty? NOWHERE, that's why you need the Bottleport Drink Holder.\r\nThe Bottleport works in any Laser, Sunfish, small keelboat or any boat where space is at a premium. It will quickly and easily screw into a 5 in. Viking Polypropylene Inspection Ports (white colored), or a 5 in. Ronstan Inspection Port with 9 in. of clearance beneath it.\r\nIt provides a way to hold a drink container that is totally secure, out of your way, immediately accessible with one hand, and provides the same watertight seal as the original lid.\r\nDid we mention that it can twist into place with a Fat Bag underneath it as well? Because it can, so you don't have to worry about sacrificing all of your small item storage space. Why has no one thought of this sooner?\r\nMakes for a great gift for that hard to buy for dinghy sailor in your like.\r\n***Note: Works only with Viking polypropylene inspection port."^^<http://www.w3.org/2001/XMLSchema#string>
