Abstract: A portable boat lounge and a method of attaching are disclosed. The boat lounge includes a fabric having a length which spans across the beam of the boat. The fabric has a first end, with a pair of first hollow sleeves formed adjacent thereto, and a second end, with a plurality of second hollow sleeves formed adjacent thereto. The boat lounge further includes a pair of brackets each having first and second hooked ends. One of the hooked ends of one of the brackets is sized to slide through one of the first hollow sleeves and be attached to a side of the boat. One of the hooked ends on the other bracket is sized such that it can slide through one of the second hollow sleeves and be attached to an opposite side of the boat such that the fabric is held taut across the beam.
