Title: Elevated walkway for improved cabin height

Description:
BACKGROUND 
     The interior cabin area of a boat is limited by the boat&#39;s exterior configuration. As a boat&#39;s exterior dimensions get smaller, the available interior space into which a cabin can be formed similarly decreases to a point at which interior cabin space is severely limited or not even possible. The boat making industry has developed several exterior features to help maximize interior cabin space. For example, some sport boats have raised cabin tops in the forward portion of the boat that are non-utilitarian deck areas, i.e., the cabin top is designed to keep water out, but not necessarily for any particular crew activity on its exterior surface. Such raised cabin tops increase the interior area of the cabin, but place limits on the use of exterior deck space. To access the forward portions of the boat deck, a center walkway between two dash panels is often utilized. Such center walkways are often designed to be the same level as the cockpit, which may be lower than the cabin top, such that they impinge on the available interior cabin space. 
     SUMMARY 
     Boats including a bow area, a cockpit, an elevated walkway, and a cabin are described. The cockpit is located behind the bow area and both include deck portions. The elevated walkway extends between the cockpit and the bow area and overlaps the longitudinal axis of the boat. The elevated walkway is elevated relative to either the cockpit deck portion or the deck portion of the bow area. The cabin is located at least partially below the elevated walkway. 
     Additional boats including a bow area, a cockpit, an elevated walkway, and a cabin are described. The cockpit of these boats is located behind the bow area and both include deck portions. The cockpit further includes a port dash console and a starboard dash console. The elevated walkway extends between the cockpit and the bow area, is elevated relative to either the cockpit deck portion or the deck portion of the bow area, and the portion of the elevated walkway proximate the cockpit is located between the port dash console and the starboard dash console. The cabin is located at least partially below the elevated walkway.

     DETAILED DESCRIPTION 
     Boats including elevated walkways that are useful for increasing cabin height in a boat, such as a bow rider style boat, are described. Such elevated walkways can be used to connect a bow area to a cockpit area. The elevated walkway is elevated relative to either the cockpit deck portion or the deck portion of the bow area. The cabin of a boat with an elevated walkway as described herein is located at least partially below the elevated walkway. The portion of a cabin below the elevated walkway has a ceiling area. that is elevated relative to either the deck portion of the bow area or the cockpit deck portion where the elevated walkway overlaps the cabin space. Elevated walkways as described herein are located on the boat such that they either overlap the central longitudinal axis of the boat or the end of the elevated walkway near the cockpit is located between port and starboard dash consoles. 
       FIG. 1  shows a perspective view of one example of a boat  10  with an elevated walkway  20 . The boat shown in  FIG. 1 , has a bow area  30 , a cockpit  40 , and an elevated walkway  20  extending between the bow area  30  and the cockpit  40 . The cockpit  40  is located behind, i.e., aft, the bow area  30  and includes a deck portion  50 . The bow area  30  also includes a deck portion  55 . The elevated walkway  20  is elevated relative to either the cockpit deck portion  50  or the deck portion  55  of the bow area  30 . Similarly, the elevated walkway  20  can be elevated relative to both the cockpit deck portion  50  and the deck portion  55  of the bow area  30 . 
       FIGS. 2 and 3  are cross-sectional views of the boat  10  from  FIG. 1 .  FIG. 2  is a cross-sectional view of the boat  10  looking from the middle of the boat  10  toward the port side (the cross-section being taken along the longitudinal axis of the boat from bow to stern).  FIG. 3  is a cross-sectional view of the boat  10  looking from the middle of the boat  10  toward the starboard side (the cross-section being taken along the longitudinal axis of the boat from bow to stern). Both  FIGS. 2 and 3  show a cabin  60  located at least partially below the elevated walkway. In the specific example shown in  FIGS. 2 and 3 , the elevated walkway  20  is elevated relative to both the deck portion  55  of the how area  30  and cockpit deck portion  50 . However, in other examples, the elevated walkway  20  can be elevated relative to only the deck portion  55  of the bow area  30  or only the cockpit deck portion  50 . Similarly, in further examples, the elevated walkway  20  can be elevated at different levels relative to the cockpit deck portion  50  and the deck portion  55  of the bow area  30 . For example, the cockpit deck portion  50  can be lower in elevation than the deck portion  55  of the bow area  30 , while elevated walkway  20  is elevated relative to both the cockpit deck portion  50  and the deck portion  55  of the bow area  30 . The elevated walkway  20  can be elevated 1 or more inches, 2 or more inches, 3 or more inches, 4 or more inches, 5 or more inches, 6 or more inches, 8 or more inches, 10 or more inches, 12 or more inches, 14 or more inches, 16 or more inches, 18 or more inches, 20 or more inches, or 24 or more inches above either the cockpit deck portion  50  or the deck portion  55  of the bow area  30 . Steps or a ramp, for example, can be used to transition between the cockpit deck portion  50  or the deck portion  55  of the bow area  30  onto the elevated walkway  20 . 
       FIG. 4  shows a top view of the boat  10  with the elevated walkway  20  connecting the cockpit  40  to the bow area  30 .  FIG. 4  also shows a starboard dash panel  70  and a port dash panel  80 . As shown in this particular example of boat  10 , the starboard dash panel  70  houses an operating station and the port dash panel  80  houses a cabin door  90  to provide access to the cabin  60 . Access to the cabin  60  can be located at alternate positions that will be apparent to those of skill in the art. As shown in  FIG. 4 , in this example of a boat  10 , the elevated walkway  20  proximate the cockpit  40  is located between the starboard dash panel  70  and a port dash panel  80 . The starboard dash panel  70  and port dash panel  80  can be different sizes depending on the design of a particular boat.  FIG. 4  also shows the longitudinal axis  100  of the boat  10 , i.e., the longitudinal axis  100  running from bow to stern. The elevated walkway  20  shown in  FIG. 4  overlaps the longitudinal axis  100  of the boat  10 . Depending on the relative sizes of the starboard dash panel  70  and a port dash panel  80 , the elevated walkway  20  can be located such that it does not overlap the longitudinal axis  100  or a boat while the portion of the elevated walkway  20  proximate the cockpit  40  is located between the starboard dash panel  70  and a port dash panel  80 . 
       FIG. 5  shows a cross-sectional view of the boat  10  at axis  110  (shown in  FIG. 4 ) looking from the bow toward the stern (the axis  110  being perpendicular to the longitudinal axis of the boat within the length of the elevated walkway  20 ). The cabin  60 , as shown in  FIG. 5 , is located at least partially beneath the elevated walkway  20 . The cabin  60  may include one or more steps, seating areas, one or more berths, a galley, a head, or combinations of these. For example, a cabin  60  may include a seating area, a berth, a galley, and a head. A berth located in the cabin  60  can be a full beam berth. The cabin  60  may also include other areas used in boat cabins such as storage areas and general use cabin areas. 
     An additional example of a boat  10  has a bow area  30 , a cockpit  40 , and an elevated walkway  20  extending between the bow area  30  and the cockpit  40 . The cockpit  40  is located behind, i.e., aft, the bow area  30  and includes a deck portion  50 , a starboard dash console  70 , and a port dash console  80 . The elevated walkway  20  is elevated relative to either the cockpit deck portion  50  or the deck portion  55  of the bow area  30 . The bow area  30  also includes a deck portion  55 . The elevated walkway  20  proximate the cockpit  40  is located between the starboard dash console  70  and the port dash console  80 .
