The device includes a body that has a first side and a second side. A passageway is formed through the body such that the passageway has a first end adjacent to the first side and a second end that is adjacent to the second side. A sealing member is provided that includes an outer gasket and an inner gasket. The outer gasket is positioned adjacent the first side and the inner gasket is positioned adjacent the second side. A seal connector connects the inner gasket and the outer gasket and the seal connector passes through the passageway. In this way, the inner gasket and the outer gasket are mechanically attached to the ring. The sealing device is configured for use in such applications as sealing the cargo opening on the deck of a kayak. ## Claims ### Claim 1 A hatch system for a kayak, the hatch system comprising: a ring that defines an outer surface and an inner surface; an outer seal is attached to the outer surface; and an inner seal is attached to the inner surface; at least one passageway is defined through the ring from a first end adjacent to the outer surface to a second end that is adjacent to the inner surface; a cover is configured to engage the ring such that the cover is sealing y engaged with the inner seal; a connector extends through each passageway such that he connector is joined to the outer seal and the connector is joined to the inner seal; a channel defined by the ring such that the channel walls define the inner surface; and wherein the cover includes a hatch wall and the channel is configured to receive the hatch wall and the inner seal such that the inner seal is positioned between a tip of the hatch wall and a bottom surface of the channel. ### Claim 2 A hatch system according to 1, wherein the outer seal, the inner seal, and the connector are comprised of a first material and the ring is comprised a second material and the second material is stiffer than the first material. ### Claim 3 (depends on 2) A hatch system according to claim 2, the system u her comprising: a flange that defines at least a portion of the outer surface of the ring; and an outer wall that extends away from the flange and defines at least a portion of the inner sealing surface on one side and at least a portion of the outer surface on an opposing side. ### Claim 4 (depends on 3) A hatch system according to claim 3, wherein the outer seal is attached to the flange and the inner seal is attached to the channel and the inner seal includes a hatch seal outer wall and a hatch seal inner wall that are spaced-apart and substantially parallel to each other. ### Claim 5 (depends on 2) A hatch system according to claim 2, wherein the ring is attached to a kayak. ### Claim 6 (depends on 5) A hatch system according claim 5 wherein the boat includes a deck that has an opening formed in it and the ring is positioned near the opening. ### Claim 7 (depends on 6) A hatch system according to claim 6, wherein a portion of the ring extends into the opening. ### Claim 8 (depends on 6) A hatch system according to claim 6, wherein a portion of the ring extends over the surface of he deck around the opening. ### Claim 9 (depends on 6) A hatch system according to claim 6, wherein the boat is a kayak.
