This is accomplished by the present invention which comprises an adjustable shaft member fitted in a cooperating support assembly mounted on the boat. The elevation of the shaft is adjusted such that its end strikes the water bottom before the bottom of the boat or its propulsion unit does so.，下面是Boat turn-brake专利的具体信息内容。

权利要求

1. A method of preventing a boat from running aground in shallow water comprising: a. providing a vertically adjustable shaft member at one corner of the boat on either side of the propulsion unit for the boat; and b. adjusting the vertical depth of the shaft member such that it extends beneath the bottom of the boat to a depth sufficient to prevent damage to the boat''s propulsion unit whereby upon the boat entering shallow waters, the extended shaft contacts the water bottom and thereby causes the boat to pivot around the shaft away from the shallow area.

2. Boat turn brake means comprising: a. base means adapted for attachment to the transom of a bOat; said base means being further defined in that it is provided with a sleeve portion adapted to receive extended shaft means; said sleeve portion being pivotably mounted upon said base means whereby shaft means operably mounted in said base means is allowed to pivot backwards upon the shaft engaging the water bottom; b. shaft means adapted for mounting within the sleeve portion of said base means; said shaft means being further defined in that it is provided with adjustable means whereby its elevation can be set as desired by the boat operator; and c. resilient spring means operably connected to the sleeve portion of said base means for constantly urging said shaft means to assume an essentially vertical position.

3. The boat turn brake means of claim 2 further characterized as comprising: d. adjustable spring loading means operably connected to said resilient spring means whereby the force exerted upon said shaft means by said resilient spring means can be adjusted.

4. The boat turn brake means of claim 3 further characterized as comprising: e. scale means operably connected to said adjustable spring loading means for indicating the force placed on said resilient spring means.

5. The boat turn brake mean of claim 4 further characterized in that: said base means is further defined as comprising pulley means connecting said resilient spring means to the sleeve portion of said base means.

6. The boat turn brake means of claim 2 further characterized in that: said base means is further defined in that the pivotably mounted sleeve portion is operably connected to said base means whereby the sleeve portion can be laterally rotated.

7. The boat turn brake means of claim 2 further characterized in that: said base means is further defined in that it is provided with a clamping portion for clamping to the transom of a boat for ease of installation and removal.

8. The boat turn brake means of claim 2 further characterized in that: said resilient spring means is operably installed in the pivotable connection between the sleeve portion and the base portion of said base means.
