Abstract
Abstract A stabilizer device for boats to maintain a boat in a substantially horizontal position during forward movement of the same and to resist tilting, rolling or bobbing movements of the boat due to wave action. The stabilizer device includes platelike means attached externally to the stern of the boat to form an extension of the bottom surface thereof against which the water may exert an upward force tending to lift the stern of the boat thereby resisting the tendency for the stern to be depressed and the bow to rise when the boat moves forwardly in the water. Means is provided forming an adjustable, yieldable connection between the platelike means and boat at a location to yieldingly resist upward movement of the platelike means and to permit vertical adjustment of the same to regulate the stabilizing action of the water on the device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
In a stabilizer for boats a platelike member adapted to be movably connected to the transom of a boat with a planar portion of the member extending rearwardly therefrom for angular movement about an axis extending transversely of the boat in position for contact with the water to apply an upward force to the transom, an elongated element hingedly connected at its lower end to and extending upwardly from the member at a location spaced rearwardly from the transom, connecting means pivotally mounted on the transom for vertical rocking movement thereon and through which said element is slidably extended, spring means surrounding said element, and threadable means on said element and said connecting means positioned for coaction with said spring means to adjust the resistance of said spring means to upward movement of said planar portion.
Claim 2
Dependent Claim
136 words
In a stabilizer for boats a platelike member adapted to be movably connected to the transom of a boat with a planar portion of the member extending rearwardly therefrom for angular movement about an axis extending transversely of the boat in position for contact with the water to apply an upward force to the transom, an elongated element hingedly connected at its lower end to and extending upwardly from the member at a location spaced rearwardly from the transom, connecting means pivotally mounted on the transom for vertical rocking movement thereon and through which said element is slidably extended, spring means surrounding said element, and threadable means on said element and said connecting means positioned for coaction with said spring means to adjust the resistance of said spring means to upward movement of said planar portion.
Claim 3
Dependent Claim
12 words
The stabilizer as claimed in claim 1, wherein said member is flexible.
Claim 4
Dependent Claim
26 words
The stabilizer as claimed in claim 1 including means positioned for coaction with said member and transom to limit downward angular movement of said planar portion.
Claim 5
Dependent Claim
135 words
In a stabilizer for boats, a platelike member adapted to be movably connected to the transom of a boat with a planar portion of the member extending rearwardly therefrom for angular movement about an axis extending transversely of the boat in position for contact with the water to apply an upward force to the transom, a bracket adapted to be secured to the transom and having a portion extending rearwardly from the transom above said planar portion, means rotatably mounted on the bracket for vertical rotational movement, yieldable means positioned for coaction with said rotatable means and member to yieldingly resist movement of said planar portion toward said rotatable means, and means forming an adjustable connection between said member and said rotatable means to limit movement of said planar portion away from said rotatable means.
Claim 6
Dependent Claim
135 words
In a stabilizer for boats, a platelike member adapted to be movably connected to the transom of a boat with a planar portion of the member extending rearwardly therefrom for angular movement about an axis extending transversely of the boat in position for contact with the water to apply an upward force to the transom, a bracket adapted to be secured to the transom and having a portion extending rearwardly from the transom above said planar portion, means rotatably mounted on the bracket for vertical rotational movement, yieldable means positioned for coaction with said rotatable means and member to yieldingly resist movement of said planar portion toward said rotatable means, and means forming an adjustable connection between said member and said rotatable means to limit movement of said planar portion away from said rotatable means.
