| Z-SPAR Jib Boxes |
|
|
Z-Spar Masts use one of several different Jib Boxes for internal Jib and/or Spinnaker Halyards
on Fractional Rigs. These Jib Boxes are also used for attachment of a Staysail stay and
Halyards. Internal Halyards exit lower on the mast, normally using standard
Z-Spar Exit Plates, or
(on older rigs) sheaves that were integrated into the Mast Foot.
For Replacement Sheaves for these Jib Boxes,
See Z-Spar Sheaves. See also:
Z-Spar Exit Blocks. |
