There was an earlier discussion of track placement, maybe that's why no response to the quesition. We'll try to find it (very likely, it was within another thread -- it's so hard to herd cats).

Building on Peter's thought, most active track placers are in the racing fleet. Cruising sailors tend not to bother. In most cases, they may not have even installed a traveler mainsheeting system, but continue to rely on Pearson's original fixed placement.

That also goes for jib control. Pearson had the jib sheets leading from a high clew sail to a block on the coach roof (reason for the aluminum straps) and then to the primary winches. Also, there was usually a short piece of track just in outside the large windows.

Pearson's Genoa and spinnaker track is placed at the outer edge of the deck back by the cockpit.

In the racing fleet, the coach roof arrangement and short jib track are replaced with a jib track located between the shrouds and the cabin trunk. For those PHRF racers using sails other than the class jib (110%) the Genoa / spinnaker track can run at the outer edged of the deck (sometimes on the toe rail) from just behind the aftermost shroud to the end of Pearson's original placement. Block placement depends on the size of the sail (120 to 180 percent).
Note that the sheets for the jib go outside the first shroud and inside the next two. Genoa sheets go outside all of the shrouds. As for specific track placement, well that's often a closely guarded secret Maybe I can get some photos that will give you some ideas. And, start a "track" thread.
