The present invention provides a water container structure, which is a container combination for an animal to drink water and comprises a containing unit, for water to be added, at an upper end and a receiving unit for the animal to drink the water with its mouth at a lower end. The present disclosure also provides for a shorter tubing junction while reducing effective width, further reducing trauma to the body. At least two working materials are used one of which can be etched without etching a substrate. Two such anchors can be installed at an angle such that their outer ends and vertical rods are far apart to provide maximal holding power to prevent the boat from weather-vaning.
