Center Board, Extend Lift Line to the Cockpit.

This feature would come in very handy if you are sailing solo in shallow water or are racing and there's simply a million things going on and can't leave the tiller.  The foredeck apes are certainly NOT going to jump into the cabin to raise or lower the board when they're busy with the spinnaker.  After all, it's within easy reach for the helmsman and he's only just steering the boat! 
 
The turning blocks are bolted in place with a wood backing block behind each.  This does a nice job of distributing the load. The black turning block at the bottom of the table pedestal is mounted on the port screw of the eye strap. 

The line across the cabin floor presents minimal tripping hazard since the natural body motion to slide behind the table is to be in a sitting position. A knot in the cockpit eliminates slack in the line when the board is down so it should bother you less. 

Note the split cushions to access to the settee lockers and Joy's nice knees!  

Below you can see the cockpit end of the 5/16" control line with the stopper knot. This is a very convenient location for the helmsman. The fairlead is lined with stainless steel to minimize chafe and reduce friction.  If you can't find a similar guide at your chandler, insert some thin stainless steel or brass tubing through a block of Delrin and use a flaring tool to form the ends round.

These modifications are on board Joy IV. 


Also note how the traveler has been raised with a strip of teak to eliminate a gathering hole for dirt.  The wood has been in place for many years and shows no sign of rotting.  Too bad such a good idea also creates a "bump" on the seat.  The bottom mainsheet block has been temporarily attached to the toe rail for clear cabin access during happy hour.  Note the colour coded control lines.
