of that halyard; the splice should be just above the
                  winch when the sail is fully hoisted.
                      If you’re replacing a properly fitted old halyard,
                  just send it down and reproduce the wire and rope
                  lengths in the new halyard. If the old one doesn’t fit
                  right, hoist the sail, measure how far off it is, then
                  send it down and adjust accordingly when you take
                  measurements off it for the new one. If the mast is
                  new, measure while it’s out of the boat. For a head-
                  sail halyard on a new mast, be sure to “loft” the
                  angle and length of the stay or you’ll come up short.
                  You’ll also get a misfit if you cleverly reeve a rope to
                  measure with, marking it “for an exact fit”; when
                  you later stretch it out as a pattern for the new hal-
                  yard, you’ll almost certainly stretch it more or less
                  than you did on the mast. Use a tape measure.

                  Variations and Aberrations                   the winch defeats the purpose of using wire.
                  There are many styles of Tail Splice, as one might
                  expect with such an arcane and complex knot. If
                  the style you use or buy is different from the one
                  described here, just be sure that it, like this one,
                  is thoroughly tested and proven. Avoid those with
                  abrupt shoulders, few tucks, or uneven appearance.
                      You’ll occasionally see a halyard proportioned
                  so that the splice is between cleat and winch when
                  the sail is hoisted (Figure 6-70D). The rationale here
                  is that the splice is the weak link and only the wire
                  should take a full strain. A variation on this involves
                  inserting the wire far enough into the rope at the
                  beginning of the splice that a wire-and-rope “sand-
                  wich” will be wrapped around the winch when the
                  sail is fully hoisted (Figure 6-70B). Both of these
                  techniques subject the wire to unnecessary abuse by
                  wrapping it around a winch designed for rope, and
                  the sandwich version, in addition, causes the wire to   Figure 6-70B. A rope-and-wire “sandwich” around
                  chafe the rope away from the inside out.     the winch results in crushed wire and chafed-through
                      But with either of these techniques the worst   rope, shortening halyard life
                  moment surely comes when you go to put a reef or
                  two in the sail. The splice that you didn’t trust in
                  light air is now exposed, along with the deformed  a wire halyard’s low weight, windage, elasticity, and
                  and weakened rope and wire on either side of it,  cost with a rope halyard’s speed and ease of han-
                  to conditions that can make you uneasy about the  dling. Properly made in the right size materials, it’s
                  stoutest gear. The Tail Splice allows us to combine  a strong link, not a weak one.
