Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
An aquatic device comprising an: elongate single hull having a vertical notch centrally through the stern thereof, operator support-means comprising a vertical post having clamp-adjustable overlapping vertical lengths for thereby adjusting the height of said operator support means, means for mounting an outboard motor at an adjustable height in the vertical notch, comprising an plate adapted for vertically slotted attachment at the forward portion of the notch with an opening therein for attachment to an outboard motor, a hinge member adapted for protrusion through the opening in the plate and having a first motor-engagement means at one end thereof and a second motor-engagement means pivotally connected with the opposite end thereof.
Claim 2
Dependent Claim
111 words
An aquatic device comprising an: elongate single hull having a vertical notch centrally through the stern thereof, operator support-means comprising a vertical post having clamp-adjustable overlapping vertical lengths for thereby adjusting the height of said operator support means, means for mounting an outboard motor at an adjustable height in the vertical notch, comprising an plate adapted for vertically slotted attachment at the forward portion of the notch with an opening therein for attachment to an outboard motor, a hinge member adapted for protrusion through the opening in the plate and having a first motor-engagement means at one end thereof and a second motor-engagement means pivotally connected with the opposite end thereof.
Claim 3
Dependent Claim
47 words
An aquatic device as recited in claim 1, wherein the elongated single hull has a central, rectilinear-section tunnel in the underside thereof extending rearwardly from an intermediate portion of the length of the hull to intersection with the lower part of the vertical notch at the stern.

Claim 6
Dependent Claim
38 words
An aquatic device as recited in claim 4, wherein the operator-support means comprises spaced hand-grips, one of the hand-grips being rigid and the other of the hand-grips having resilient control-means thereon for connection with a said outboard motor.
Claim 7
Dependent Claim
29 words
An aquatic device as recited in claim 5 wherein the operator-support means includes a cup affixed in the hull and adapted to receive one of said overlapping vertical lengths.
