That's one I can't help you with very much. I rarely used my genoa, and I
conceived a very unconventional setup that I've never been sure was a good
idea. Also my first generation, gunter-rigged P14 is quite different from
the newer models.
My tracks for the genoa are mounted on the side deck, in the location
prescribed by HMS Marine at the time I bought my genoa from them. The
fairleads and cleats for my working jib are on the cabintop. Because of the
extended sides of the cabin on the gunter rigs, there is no good place to
put a genoa cleat without making multiple sharp turns. The sharper the turn
of the sheet at a block, the greater the load on the block, maybe not a
problem on our little boats if we use substantial hardware well mounted.
Still you want to keep friction to a minimum, remembering that you will be
dragging the genoa across the side stays and mast when you tack.
My very unconventional (weird) setup is to use a continuous, endless sheet
for the genoa. The idea was so that I could tend the genoa sheet from the
windward side. But, since I only use the genoa in light air, staying on the
windward side has not been important in practice. My genoa sheet is a
single line, from the clew, through the stand-up block on the track, around
horizontal cheek blocks (Davis Blockits, no longer made) on both quarters,
back forward through the stand-up block on the track on the opposite side,
and on forward to the clew. When I tack, I move to the new windward side,
pull the sheet FORWARD to trim for the new tack, then pull the line down
into a jam cleat on the rail. The excess sheet forward of the cleat can be
dumped over the side or laid on the side deck or in the cockpit.
I hope someone with a late model P15 will describe the proper genoa setup
for you.
