and a spray inhibitor attached to a region of the boat other than the exhaust outlet; whereby the spray inhibitor inhibits a spray of water caused by exhaust gases exiting the exhaust outlet. ### Claim 2 (depends on 1) The boat of claim 1 wherein the spray inhibitor is attached to the boat with an attachment device. ### Claim 3 (depends on 2) The boat of claim 2 wherein the attachment device positions the spray inhibitor relative to the exhaust outlet to inhibit the spray of water caused by exhaust gases exiting the exhaust outlet. ### Claim 4 (depends on 3) The boat of claim 3 wherein the attachment device is attached to the boat above the exhaust outlet. ### Claim 5 (depends on 4) The boat of claim 4 wherein the spray inhibitor is removably attached to the boat. ### Claim 6 (depends on 5) The boat of claim 5 wherein the attachment device comprises a track, a core, and material forming two flaps. ### Claim 7 (depends on 6) The apparatus of claim 6 wherein the track is secured to the boat, and the core slides through, and is able to rotate within, the track. ### Claim 8 (depends on 7) The apparatus of claim 7 wherein the spray inhibitor is secured between the two flaps of the attachment device. ### Claim 9 (depends on 8) The apparatus of claim 8 wherein the spray inhibitor further comprises two layers of material. ### Claim 10 (depends on 9) The apparatus of claim 9 wherein the spray inhibitor further comprises one or more weights between the two layers of material. ### Claim 11 (depends on 10) The apparatus of claim 10 wherein the spray inhibitor further comprises a tie-down device. ### Claim 12 (depends on 11) The apparatus of claim 11 wherein the tie-down device attaches to the boat to ensure that the spray inhibitor does not slide substantially out of position relative to the exhaust outlet. ### Claim 13 (depends on 12) The apparatus of claim 12 wherein the spray inhibitor further includes a handle. ### Claim 14 A spray inhibitor for inhibiting a spray of water caused by exhaust gases exiting an exhaust outlet on a boat, wherein the spray inhibitor includes an attachment device for attaching the spray inhibitor to a region of the boat other than the exhaust outlet. ### Claim 15 (depends on 14) The spray inhibitor of claim 14 wherein the attachment device is configured to position the spray inhibitor relative to the exhaust outlet on a boat to inhibit the spray of water caused by exhaust gases exiting the exhaust outlet. ### Claim 16 (depends on 15) The spray inhibitor of claim 15 wherein at least part of the attachment device is configured to attach to a boat above the exhaust outlet. ### Claim 17 (depends on 16) The spray inhibitor of claim 16 wherein the attachment device comprises a track, a core, and material forming two flaps. ### Claim 18 (depends on 17) The spray inhibitor of claim 17 wherein the core slides through, and is able to rotate within, the track. ### Claim 19 (depends on 18) The spray inhibitor of claim 18 wherein a portion of the spray inhibitor is secured between the two flaps of the attachment device. ### Claim 20 (depends on 19) The spray inhibitor of claim 19 further comprising two layers of material. ### Claim 21 (depends on 20) The spray inhibitor of claim 20 further comprising one or more weights positioned between the two layers of material. ### Claim 22 (depends on 21) The spray inhibitor of claim 21 further comprising a tie-down device. ### Claim 23 (depends on 22) The apparatus of claim 22 wherein the spray inhibitor further includes a handle. ### Claim 24 (depends on 22) The apparatus of claim 22 wherein the tie-down device ensures that the spray inhibitor does not slide substantially out of position relative to the exhaust outlet. ### Claim 25 (depends on 14) The spray inhibitor of claim 14 wherein the spray inhibitor further comprises at least one layer of material. ### Claim 26 (depends on 25) The spray inhibitor of claim 25 wherein the at least one layer of material further includes at least one weight attached thereto. ### Claim 27 (depends on 16) The spray inhibitor of claim 16 wherein the attachment device allows the spray inhibitor to hang from a boat. ### Claim 28 (depends on 27) The spray inhibitor of claim 27 wherein the spray inhibitor is attached to the attachment device at a first end of the spray inhibitor, and a second end of the spray inhibitor hangs relative to the exhaust outlet on a boat to inhibit the spray of water caused by exhaust gases exiting the exhaust outlet.
