One member wrote in asking what were some of the options for rigging topping lifts, as the topping lift on his boat
provided little mechanical advantage. As with almost any kind of traditional rigging,
i] | there are many versions of topping lifts. Although there may be other, possibly better .
@ options out there, I have illustrated some variations with which I am familiar. is

through a single whip at the masthead. a
On a larger craft, two issues conspire to make this a more difficult dal

masthead whip is most often lower than it is on a polemasted vessel.
This means that the angle from masthead to boom end is signifi-
cantly flatter reducing the amount of mechanical advantage. The other factor is simply that a
bigger rig means more weight to lift. One way to improve mechanical advantage is to fix

AN larly popular * A a fo;
after the First “gn |
World War, utilizes twin lifts ‘—w ih
sometimes called lazy-lifts as they include the lazy-jacks in their make up. 7 i aN a
In this version two lifts run from the main-sheet bail on either side of the Ses
sail and gaff to a single block for each lift under the spreader, trestle or fice)
hounds, and then down to the deck. About halfway up
each lift hangs a short sling with a wooden thimble or lizard at the ae
bottom end of the sling. The lazy-jack runs from the boom up through |
one thimble then down around the boom and back up through the or
other thimble and finishes back at the boom. { ‘
There are several advantages to this system. One is that the angle of the lifts are less flat because the topping lifts end at
the mainsheet bail rather than the end of the boom, improving the mechanical advantage. The other is that you can place
a crewmember on each topping lift, effectively doubling the applied muscle. Another advantage is that the gaff and
mainsail are less likely to run afoul of your topping lifts because even when fully lowered they lie
between the two lifts.
i The disadvantages to this system become apparent with really large rigs. It is possible for
g°) the weight to exceed the strength of two of even the strongest crewmembers. In this case one
Dh solution is to fix the end of the topping lift to a luff tackle on deck. This gives a mechanical advan-

eo chafing. We went to this rig
because we have a 32′ boom
with 620′ of mainsail and it makes it possible for me to take the boat out with only
one other person on board to take the helm. I can’t say I have noticed any chafing
and considering the combined weight of boom, mainsail, and gaff, I can’t say the
additional weight of two double blocks aloft has been noticeable.
To paraphrase the old adage: every problem may have a solution but every solution has its problems. The choice
of topping lift on your vessel is a question of fitting the type of lift to the type of sailing you do, the size of the vessel, and
the number of crew that you typically have. Also, all of us have idiosyncrasies, what we’re used to, and that too becomes
an important part of the mix. If the system you have works, then I certainly would not mess with it; for anyone else, I
hope these illustrations are helpful.
