Is buying a larger Boomkicker model
Not necessarily. Using a larger model than
needed can result in too much force making
it difficult to pull on the vang and mainsheet.
If however the length of a larger model
will fit the area above the vang better,
we can substitute or exchange the standard
spring rods for optional lighter ones.
Do I need a vang with the new track fitting.
Although a vang is recommended for sail
shape, there is usually enough travel in
the track compared to the original boom
fitting, that a vang is not required.
How do you get the mast slide in
the luff groove when the mast is stepped
and the gooseneck is in the way?
The slide is removable from the fitting
and can often be inserted where the sail
goes in above the gooseneck, then slid down
into position. Using string to lower the
slide is one option. Dropping it is another,
making sure the slide can not go all the
way to the keel.
A round slide came standard, the
luff groove requires a flat slide, are these
We stock flat slides from 1/2" to 1"
wide depending on the model. Slides are
1/8" thick stainless. Measure the inside
of the existing groove or the sail slides
to determine the required width. Flat slides
can be bought direct or the standard round
slide can be exchanged, the parts list included
with the Boomkicker has specifics.
The luff groove is not usable
or does not exist below the gooseneck. How
is the fitting attached?
The mast fitting bracket can be attached
directly to the mast using the same drill
and tap provided for installing the boom
fitting. Extra long screws are included
if needed. The slide goes unused. For unusual
cases, for example where wiring runs in
the luff groove, we can supply custom brackets
to span the luff groove.
There is a groove on the underside
of the boom, are there slides available
for the boom fitting?
Yes. Contact us with the required inside
width. Slides are 1/8" thick stainless,
drilled and tapped for the fitting. Shorter
screws are also included. Before ordering,
check for access.
The existing gooseneck is adjustable
up and down the mast. Is this a problem?
The Boomkicker works best with the boom
gooseneck fixed at one location on the mast.
After installation, the Boomkicker boom
attachment becomes a lever point. Raise
the gooseneck and the aft end of the boom
drops. It is preferred to select the best
gooseneck position, when using the halyard
or a cunningham to tighten the luff. Use
the downhaul/sailstops to fix the gooseneck
in that position. We also sell slides separately
The boom rolls on a gooseneck pin.
Is this a problem?
Not with the smaller models, but as boats
approach 30', to avoid undue stress on the
boom fitting, it is best if booms are fixed
in the upright position. If necessary we
have a fitting which mounts on the mast,
under the gooseneck to hold the boom in
the upright position.
Does the Boomkicker need to be installed
parallel to the vang?
Usually it looks best, but it is not essential.
So long as there is room to flex and it
provides enough support, the installation
is fine. For more see next question.
For installation, is the best angle
to the boom 45 degrees?
Actually, the farther out the boom the better
the leverage for support. The best angles
to the boom for all models except the two
smallest are between 35° and 40°
but customers often install them successfully
at angles close to 30°. If shortening
the Boomkicker is necessary to fit above
the vang, shorten only the minimum amount
required. The exceptions are models K0312
and K0400. Both work best if installed between
40° and 45°, see their installation
instructions for more.
How high should I set the boom for
With the new boom track fittings' extended
travel, setting the boom height is not as
critical as the original fitting. Generally
it should be slightly above the normal sailing
height with consideration given to reefing,
head clearance when in port, lifting the
boom in light air to improve sail shape
and different mainsails.
Can I install the Boomkicker upside
down so it flexes downward?
Yes, the Boomkicker works the same whether
it flexes up or down. Customers have installed
it "outside" the vang, flexing
it down away from the vang but vang leads
and interference with crew should be considered.
We have also heard of customers running
the vang between the rods, one fitting outside,
the other inside the vang. The two smaller
models which use a webbing sling at the
boom actually benefit by flexing down. As
the rods flex, the sling becomes more vertical,
better capturing the boom.
When leaving the boat for an extended
time, does the Boomkicker need to be left
in the straight position?
No. Leaving some flex in the spring rods
is fine. If left heavily flexed in hot weather
for an extended period, some set could occur.
How much travel or flex is available?
If uncut, the spring rods provide around
6 feet of travel at the aft end of the boom
depending on the setup. Most boats require
only a foot or two of travel. Shortening
the spring rods reduces travel. At their
minimum lengths, travel is still around
3.5' at the aft end of the boom, again,
depending on the setup.
Can the spring rods wear out?
The indication since 1990 is no.
Once installed, the force is more
than I like. Are smaller diameter rods available?
Yes. If uncut, the spring rods can be exchanged
for an optional set, see the parts sheet
included with the Boomkicker for specifics.
Rods can also be purchased on line at the
price list or by email and phone.
After using the Boomkicker for a
time, I would prefer the boom higher. Do
I need to order longer spring rods or drill
No, not with the new track boom track fitting,
just adjust the clevis pin stop. Additional
stop holes can be drilled for the 3/16"
diameter pin using the inscribed line along
the track as a guide.
