Three Leeward 16 Centerboard Assemblies
Found in Luger catalogs and blueprints

Several Leeward 16 centerboard systems have been used to raise and lower the centerboard, or to brace the centerboard trunk over the course of the boat's 23-year production run.  Changes were made as production materials and assembly methods changed.  Listed below are three centerboard systems Luger detailed in the Owner Assembly Plans (blueprints) for the popular daysailer.

An example of the earliest centerboard system - 1960s Era
(Used to raise/lower a metal centerboard on a Leeward with raised plywood floorboards)

This system used two blocks to assist the sailor in raising the heavy metal centerboards of the earliest Leewards.  The photos and diagrams (redrawn from original blueprints) illustrate the rope's path from the centerboard, through two blocks, and eventually cleated to the aft end of the centerboard trunk.  The vertical post, seen in the lower left photo, not only acts as the anchoring point for the Double Block, but also helps steady the centerboard well and serves as the mast post.

The diagram on the left shows the blocks used to easily raise and lower the metal centerboard.  The diagram shows the position of the parts used in this centerboard system, and how their attachment points.

The bottom diagram illustrates the path of the rope.  The centerboard rope is attached to the becket block, which is shackled to the centerboard.

From the becket block, the rope follows a path around the top sheave of the double block (attached by an eye strap to the mast post assembly), then returns to go around the becket block.

The rope then returns, to run below the upper rope section and go around the lower sheave of the double block.  From the double block the rope is cleated to the aft end of the centerboard trunk.

In Leewards of the 1980s, the centerboard is never seen from the cockpit, whereas sailors using this early CB system would see the centerboard when it was in the raised position.  Flexible gasket material (above or below the slotted well cap) could be used to prevent water from splashing into the boat when the centerboard was lowered.

This CB System was demonstrated in catalogs by the late 1970s
(Note the seat-level horizontal board spanning the width of the cockpit.)

By 1979 Luger, Leeward had substituted its heavy metal centerboard with a wooden CB (centerboard) which was fully enclosed within a capped trunk.  The pivoting centerboard allowed the CB to swing up and over underwater obstructions, and could retract completely within the hull for beaching and trailering. 

This centerboard assembly was probably one of the most stable systems used by Luger.  Unfortunately, it also prevented easy movement within the cockpit area.

This CB System was demonstrated in the 1980 catalog
(Note the triangular board bracing the centerboard trunk)

Leeward's pivoting centerboard is hinged to swing back and up, and retracts completely within the hull inside its fully enclosed centerboard trunk. 

The centerboard can be positioned at any setting, from fully up to all the way down, varying the Leeward's draft from 18" to 35" (4" to 35" with optional tip-up rudder).

A triangular stabilizing board is attached to the aft end of the centerboard trunk, to prevent any side-to-side movement that could weaken the vulnerable trunk-to-hull joint. 

Please note:  If the mainsheet is attached to the centerboard cap (as shown in this photo), there is considerable strain placed on the CB trunk with each tack and when the Leeward is under full sail, so particular attention should be given to the triangular board's attachment to the hull so it will provide adequate protection.
