Abstract
Abstract A trolling board for a boat has a plate for creating drag and retarding the movement of the boat through water, and a pair of spring channels for slidably and pivotally receiving a longitudinally extending bar connected to an end of the plate. Preferably, a pair of boards are symmetrically mounted on the transom of the boat. The plates are arranged to pivot about a horizontal axis which is parallel to the transom when a force is applied thereto which is in excess of a predetermined force.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
A trolling apparatus adapted for mounting on the transom of a power-driven boat, comprising in combination: a pair of vertically extending, laterally spaced-apart channel means having attachment means for mounting on a boat transom; a horizontally disposed, elongate cross member having each end thereof adapted for mounting respectively in each channel means, so that the cross member can be moved along the pair of channel means in a direction transverse to the longitudinal axis of the cross member; an elongate plate member rigidly attached at one end thereof to the horizontal cross member and extending downwardly, said plate member being adapted to move in a vertical direction, when the cross member is moved along the pair of channel means; mounting means for slideably mounting each end of the cross member respectively in each channel means, said mounting means adapted to provide for rotation of the cross member about its longitudinal axis when a force in excess of a predetermined force is applied to the plate member; control means for varying the vertical disposition of the plate member relative to the pair of channel means.
Claim 2
Dependent Claim
184 words
A trolling apparatus adapted for mounting on the transom of a power-driven boat, comprising in combination: a pair of vertically extending, laterally spaced-apart channel means having attachment means for mounting on a boat transom; a horizontally disposed, elongate cross member having each end thereof adapted for mounting respectively in each channel means, so that the cross member can be moved along the pair of channel means in a direction transverse to the longitudinal axis of the cross member; an elongate plate member rigidly attached at one end thereof to the horizontal cross member and extending downwardly, said plate member being adapted to move in a vertical direction, when the cross member is moved along the pair of channel means; mounting means for slideably mounting each end of the cross member respectively in each channel means, said mounting means adapted to provide for rotation of the cross member about its longitudinal axis when a force in excess of a predetermined force is applied to the plate member; control means for varying the vertical disposition of the plate member relative to the pair of channel means.
Claim 3
Dependent Claim
21 words
A trolling apparatus as set forth in claim 1, wherein the cross member and the plate member are of unitary construction.
Claim 4
Dependent Claim
29 words
A trolling apparatus as set forth in claim 1, wherein a pair of the trolling apparatus are adapted for mounting in spaced-apart relationship on the transom of a boat.
Claim 5
Dependent Claim
33 words
A trolling apparatus as set forth in claim 1, wherein the cross member has a rectangular cross-section and the mounting means includes spring channel means for slideably and pivotally receiving the cross member.
Claim 6
Dependent Claim
25 words
A trolling apparatus as set forth in claim 4, wherein there are a pair of trolling apparatus symmetrically mounted on the transom of the boat.
Claim 7
Dependent Claim
112 words
In combination, a boat having a transom, and a trolling apparatus comprising in combination: a plate for creating adjustable drag and retarding the movement of the boat through water; a longitudinally extending bar having a rectangular cross-section connected to one edge of the plate; spring channel means for slideably and pivotally receiving the bar for movement in a plane transverse to the longitudinal axis of the bar, and for pivotal movement about a horizontal axis which is parallel to the transom of the boat when a force in excess of a predetermined force is applied to the plate; and means for attaching the spring channel means to the transom of the boat.
Claim 8
Dependent Claim
112 words
In combination, a boat having a transom, and a trolling apparatus comprising in combination: a plate for creating adjustable drag and retarding the movement of the boat through water; a longitudinally extending bar having a rectangular cross-section connected to one edge of the plate; spring channel means for slideably and pivotally receiving the bar for movement in a plane transverse to the longitudinal axis of the bar, and for pivotal movement about a horizontal axis which is parallel to the transom of the boat when a force in excess of a predetermined force is applied to the plate; and means for attaching the spring channel means to the transom of the boat.
Claim 9
Dependent Claim
24 words
A structure as set forth in claim 6, wherein there are a pair of trolling apparatus symmetrically mounted on the transom of the boat.
