Abstract: A water filled mattress including a top sheet of flexible material that is capable of having a bottom sheet of flexible material joined by heat sealing. The top and bottom sheet are joined at their peripheries and form a waterproof enclosure. The waterproof enclosure is capable of retaining an amount of water. The waterproof enclosure has a circumferential border with a front end and a rear end. A plurality of heat welds intermittently join the top sheet and the bottom sheet to form a plurality of seams. Each seam is linearly aligned along the waterproof enclosure. Each seam ends at an identical distance. A headrest is formed within the waterproof enclosure adjacent the seam ending.

Abstract: A commercial sport fishing boat has an upper deck plan which includes forwardly directed walkways extending along either side of a central cabin. The cabin side walls are formed such that they define outwardly directed benches adjacent each walkway while providing adequate interior overhead in the cabin. The walkways and benches increase the boat's linear rail space and therefor the sport fisherman capacity. The boat further includes the conventional equipment of this type of craft.
