A small watercraft includes expanded storage capacity so as to accommodate more of the type of articles that rider's typically what to carry on the watercraft. Such articles include, for example, towels, water skis, tow ropes, etc. At least one of the storage compartments on the watercraft is formed by an opening on an upper deck section. A container is affixed to the deck below the opening and has an upper end defined by a flange that extends from walls of the container. The flange is attached to an interior wall of the upper deck section so that the container and the corresponding upper deck section form a storage compartment. The upper end of the container, however, has a larger area than the opening in the deck so as to maximize the storage space within the compartment without weakening the deck and minimizing the area through which water can enter the hull.

The invention of claim 5 wherein said contact arm is flexible. 7. The invention of claim 2 wherein said drag stabilizer comprises a flexible chain. 8. A guidance system for guiding a seeder towed by a vehicle, said guidance system sensing locations of standing stubble rows left by a previous crop and in response to said sensing guiding the seeder so that furrow openers of said seeder travel on a preferred path between said standing stubble rows, said guidance system comprising: a row location sensor mounted on said seeder and adapted to sense the location of said standing stubble rows by sensing a furrow in the ground from which said standing stubble rows extend; a seeder position adjuster, said adjuster responsive to said steering signals; where in operation said row location sensor is in a neutral position when the furrow openers of said seeder are travelling on the preferred path between the standing stubble rows, and wherein when the seeder deviates from its preferred path said row location sensor sends the steering signal to said seeder position adjuster which causes said adjuster to move the seeder to one side or the other relative to the towing vehicle so as to direct said seeder back on to the preferred path. 9. The invention of claim 8 wherein said row location sensor measures a distance from a seeder frame to the ground at two laterally spaced points and senses the difference between these two distances to determine the location of said furrow and thereby senses the location of said standing stubble rows. 10. The invention of claim 9 wherein said row location sensor uses sonar to determine said distances from the seeder frame to the ground. 11. The invention of claim 9 wherein said row location sensor uses radar to determine said distances from the seeder frame to the ground. 12. The invention of claim 9 wherein said row location sensor comprises first and second laterally spaced sensing elements adapted to ride along the ground, each of which may move vertically independently of the other and wherein said steering signals are generated by the vertical movement of one said sensing element relative to the other. 13. The invention of claim 12 comprising: a sensing element frame; said first sensing element pivotally attached to said sensing element frame about a horizontal axis substantially perpendicular to the direction of seeder travel such that said first sensing element may pivot up and down; said second sensing element pivotally attached, at a point laterally spaced from said first sensing element, to said sensing element frame about a horizontal axis substantially perpendicular to the direction of seeder travel such that said second sensing element may pivot up and down; a first contact element extending from said first sensing element in the direction of said second element; upper and lower second contact elements extending from said second sensing element in the direction of said first sensing element such that when said first sensing element moves up relative to said second sensing element, said first contact element comes in contact with said upper second contact element, sending a first steering signal to said seeder position adjuster, and such that when said first sensing element moves down relative to said second sensing element, said first contact element comes in contact with said lower second contact element, sending a second steering signal to said seeder position adjuster. 14. A guidance system for guiding a seeder towed by a vehicle, said guidance system sensing locations of standing stubble rows left by a previous crop and in response to said sensing guiding the seeder so that furrow openers of said seeder travel on a preferred path between said standing stubble rows, said guidance system comprising: a first row location sensor mounted on said seeder and adapted to sense the location of said standing stubble rows, said first row location sensor sending a first steering signal when said first row location sensor senses that said furrow openers have deviated from said preferred path; a second row location sensor mounted on said seeder at a different location from the first row location sensor and adapted to sense the location of said standing stubble rows, said second row location sensor sending a second steering signal when said second row location sensor senses that said furrow openers have deviated from said preferred path, and a control by which the operator may select which of said row location sensors guides the seeder, thereby allowing an operator to choose the row location sensor where said standing stubble rows or furrows are most suitable and avoid a row location sensor position where said standing stubble rows have been trampled by a previous field operation; a seeder position adjuster, said adjuster responsive to said steering signals; where in operation said row location sensor is in a neutral position when the furrow openers of said seeder are travelling on the preferred path between the standing stubble rows, and wherein when the seeder deviates from its preferred path said row location sensor sends the steering signal to said seeder position adjuster which causes said adjuster to move the seeder to one side or the other relative to the towing vehicle so as to direct said seeder back on to the preferred path. 15. The invention of claim 14 wherein said control allows the operator to select both row location sensors to be operating, thereby allowing both said row location sensors to send steering signals to the seeder position adjuster. 16. A guidance system for guiding a seeder towed by a vehicle, said guidance system sensing locations of standing stubble rows left by a previous crop and in response to said sensing guiding the seeder so that furrow openers of said seeder travel on a preferred path between said standing stubble rows, said guidance system comprising: a row location sensor mounted on said seeder and adapted to sense the location of said standing stubble rows, said row location sensor sending a row steering signal when said row location sensor senses that said furrow openers have deviated from said preferred path; a furrow sensor attached to said seeder such that said furrow sensor follows an end furrow of a previous seeding pass thus acting as a marker to properly space a present seeder pass from the previous seeder pass, said furrow sensor sending a furrow steering signal when said furrow sensor is moved perpendicular to the direction of seeder travel by the deviation of the seeder from the preferred path, and further comprising a control whereby the operator can select which of said steering signals, that of said row location sensor or said furrow sensor, guides said seeder; a seeder position adjuster, said adjuster responsive to said steering signals; where in operation said row location sensor is in a neutral position when the furrow openers of said seeder are travelling on the preferred path between the standing stubble rows, and wherein when the seeder deviates from its preferred path said row location sensor sends the steering signal to said seeder position adjuster which causes said adjuster to move the seeder to one side or the other relative to the towing vehicle so as to direct said seeder back on to the preferred path. 17. The invention of claim 16 wherein said furrow sensor comprises a curved tube adapted to follow said end furrow of the previous seeder pass, said tube attached to said seeder such that said tube may pivot vertically and laterally, and wherein said steering signal is generated by a lateral angular position of said attachment. 18. The invention of claim 16 wherein said furrow sensor comprises first and second laterally spaced sensing elements adapted to ride along the ground, each of which may move vertically independently of the other and wherein said steering signals are generated by the vertical movement of one sa
