all for the quest for the bet-
ter mousetrap, but my fi rst
thought was that the tradi-
tional Highfi eld lever already
did the job quite adequately.
After all, it is simply an
over-center lever that allows
one to tension a removable
inner forestay. Where’s the
problem?
Gerry explained that the
Highfi eld lever has many
moving parts, an anathema to
reliability. Most require that
you remove a clevis pin to fi x
or free the stay. That may be
a simple task at the dock, but
on the foredeck of a pitch-
ing vessel, the pin is as likely
as not to be lost; then you
have an oi cial “situation.”
Because the lever is secured
in its closed position by a slid-
ing ring, it is prone to being

caught by fl ailing sheets, and
the lever could accidentally
open as a result. Highfi elds
are bulky and, to the more
discerning eye, not very
elegant- looking. Add to those
negatives the fact that they
are inexplicably expensive.
Gerry broke down the
Highfi eld lever into its core

parts and purposes, exper-
imented, and fi ddled. His
eureka moment came with an
insight into the basic physics
behind developing the power
required to tension the wire
versus the length of the throw
of a short lever.

In his Hooklever NZ, Gerry
has found a mechanical mul-
tiplier that is as simple as it
is safe. He has signifi cantly

reduced the number of mov-
ing parts, resulting in a lighter
and far more elegant-looking
piece of equipment. Whereas
the tension on the standard
lever pulls in a direction tend-
ing to open the device, Gerry’s
design pulls in a way that has
a neutral ef ect. This, coupled
with the way in which he has
recessed the retainer ring into
the lever handle and main body,
lessens the chance of acciden-
tal openings. Gerry’s strongest
selling point will be that he can
of er all these improvements at
approximately half the cost of
what’s now on the market.

e hear it all the time:
Yankee ingenuity,
German precision, Italian
elegance. To be sure, these
are stereotypes, but the
origins of these perceptions
can be found embedded in
the nuances of each group’s
national character. Perhaps it
is a matter of priorities and the
unique ways in which dif erent
peoples approach their dif er-
ent challenges.
In a nation traditionally liv-
ing close to the bone, with
scant physical and fi nancial re-
sources, New Zealanders’ basic
approach to problem solving
has been dubbed “No. 8 fencing
wire,” for it’s believed that any-
thing can be fashioned or fi xed
with a spool of it. If the Yanks
are the can-do people, the
Kiwis are the make-do people.

While fi nishing up a long
refi t on our cutter Roger
Henry, I found an alarmingly
frayed headstay wire. That
led me to rigger Gerry Jacobs.
In the course of our re-rig,
Gerry mentioned that he had
invented a new version of an
inner forestay tensioner. I am

ger who’s come up with a
better way to tension an
inner forestay (above left).
A padeye and long shackle
(above center) detach from
the Hooklever NZ (above

removed. When tensioned,
the inner forestay can be
used to set a staysail or
storm jib (left).

Eureka!
The Hooklever NZ
benefits from few
moving parts, can’t acci-
dentally open if hit with
a sheet, and is available
at half the cost of the
traditional hardware.
