Abstract

A tandem-reel realignment winch system having two rotatable reels and a line wound around each of the reels. The line is wound in a first direction around the first reel and in a reverse direction around the second reel to compensate for the deviation in line alignment caused by the first reel. The winch system is adapted to raise and lower objects such as keels, anchors, bouys, mast riggings and the like.

Claims

1. Apparatus comprising a tandem-reel winch system, a line and a centerboard keel;

wherein said tandem-reel winch system comprises a first cylindrical reel, a second cylindrical reel in series with said first reel, and a means for rotating said reels;

wherein said line is wound in a first direction around said first reel;

wherein said line runs from said first reel around a substantial portion of the periphery of said keel to said second reel;

wherein said line is wound in a reverse direction around said second reel; and

wherein said keel can be raised or lowered by rotation of said reels.

2. Apparatus in accordance with claim 1 further comprising two keelson plates and a center pin in said keel;

wherein a recessed track adapted to receive said center pin is formed in said keelson plates;

wherein said center pin is positioned for movement in said recessed track; and

wherein said center pin moves along said recessed track as said keel is raised or lowered.

3. Apparatus in accordance with claim 2 wherein said winch system is positioned on the deck of a boat hull and wherein said apparatus further comprises a track means allowing movement of said winch system along said deck.

4. Apparatus in accordance with claim 3 wherein said winch system further comprises two plates between which said reels are positioned and by which said reels are supported;

wherein said track means comprises two parallel tracks running along said deck;

wherein said plates can be secured to said tracks at various positions along said tracks by a securing means.

5. Apparatus in accordance with claim 4 wherein said securing means comprises a journalled guide attached to each of said plates and locking screews;

and wherein said tracks include holes for receiving said locking screws.

6. Apparatus in accordance with claim 3 further comprising a deck pin positioned in said keel;

wherein said deck pin provides support to said keel and moves along said deck as said keel is raised or lowered.

7. Apparatus in accordance with claim 3 further comprising two pulleys positioned on said deck;

wherein said line is also wound around each of said pulleys.

8. Apparatus in accordance with claim 7 wherein the number of turns of said line around said first reel equals the number of turns of said line around said second reel thereby causing the portion of line running from said first reel to the first pulley to be aligned with the portion of said line running from said second reel to the other pulley.

9. apparatus comprising a tandem-reel realignment winch system and a centerboard keel;

wherein said tandem-reel realignment winch system is adapted to raise and lower objects and is comprised of two reels in series, a means to rotate said reels and a line;

wherein said line is wound in a first direction around one of said reels in a plurality of windings to create a deviation in line alignment;

wherein said line is wound in a reverse direction around the other of said reels to compensate for said deviation;

wherein the line of said winch system runs along a substantial portion of the periphery of said keel and provides support to said keel; and

wherein said keel can be raised or lowered by rotation of said reels.

10. Apparatus in accordance with claim 9 wherein said winch system is moveable along a track means.

11. Apparatus in accordance with claim 9 further comprising two keelson plates and a center pin in said keel;

wherein a recessed track adapted to receive said center pin is formed in said keelson plates; and

wherein said center pin is positioned for movement in said recessed track.

12. Apparatus in accordance with claim 11 further comprising a deck pin positioned in said keel.
