5.17.4 Spinnaker Gear (continued)
well be used on smaller ones. In beam reaching conditions,
when the pole is up against the headstay, an unnatural load is put on the
mast, stay, and pole. The reaching strut allows for a better angle of pull
for the after guy, pulling the pole off the headstay and thus reducing the
loads to a safer point. This also eliminates chafe of the after guy on the
upper shroud. To save wear and tear, read up on spinnakers and then have a
couple of experienced friends join you for the first couple of spinnaker
drills.
5.17.5 Reefing Gear
Two methods of mainsail reefing, roller and cringle (jiffy reefing), are
in common use and their pros and cons could be discussed forever. On
boats that have their mainsheet on the end of the boom, there may be a
roller reefing mechanism contained in the gooseneck fitting. An optional
GEARED ROLLER REEFING GOOSENECK may be installed in which a handle cranks
the boom around and the sail is rolled down around the boom.
With mid-boom sheeting, most people will use the optional ''Cringle Reef
System", which is well illustrated and explained by drawing STD-00-0030. This
system is quite fast, provides better "sail shape control" than does roller
reefing and is definitely recommended for the racing skipper. It is really up
to you to figure out if you want to go to roller reefing or cringle reef.
After having consulted your own local experts you will know enough so
anything we can add would be superfluous:
5.17.6 Folding Mast and Hinged Mast Steed
