A GUIDE TO SELECT NG YOUR STEERING SYSTEM
Not too long ago wheel steering was only associated with large
ocean racing and traditional sailboats. The rapidly growing trend
towards wheel steering has changed to include cruising and rac-
ing sailboats as small as 18 feet. Many people once believed the
only way toget theUfeel'-of a sailboat was with a tiller.The popu-
larity of wheel steering as well as its practicality has shown even
the most adamant tiller man that "better feel" and "better boat
control" can be obtained with wheel steering. Without the tiller
sweeping theentire cockpit, the crew can perform more function-
ally, guests can relax more comfortably, and short-handed
family sailing suddenly becomes simple.
Planning a steering system for a tiller conversion, or an option
on a new boat is not a casual matter and should be done with the
utmost thought and consideration. More time should go into the
planning of acockpit than any other part of the boat, this is where
the crew spends the vast majority of their time whether the boat
is for cruising or racing. Moreover, the cockpit is the base for
handling sails as well as steering. Thus, in this one area of the
boat, comfort, convenience, performance and safety are all
equally vital factors, neglect even one and the pleasure of sailing
is in ieooardv.
A major part of planning agood steering installation islocating
thesteerer. This must take intoconsideration location of the rud-
derpost, winches, main sheet, and engine controls. All must be
located properly or moved to the appropriate location for a func-
tional and comfortable cockpit.
The aft cockpit steering location is normally associated with
, ,the older traditional design where a worm gear type steerer at-
iachesdirectly to a rudderpost located in the aft end of the cock-
'Opit. It is also the location used for the New Edson Rack and
:@ Pinion Steerer installed abovedeck directly toarudderpost locat-
ed in thevery aft end of the cockpit, or with atransom hung rud-
der. The pedestal typesteerer is often located well aft in thecock-
pit in cruising and racing boats (minimum distance 21 inches
from the pedestal centerline to the aft cockpit bulkhead).
Theadvantageof any of theseaft steering installations is that
the helmsman is well aft out of theway of crew members working
winches. From this position the helmsman sees all the action,
can cast off sheets or tail winches, participate in cockpit conver-
sation, and has a complete view of the sails and rig.
In the mid-cockpit installation the helm is farther forward
where the boat is wider so the helmsman can get more outboard;
instruments mounted in the cabin bulkhead can be'easily read;
the winches and cleats are more accessible to the helmsman
whether they are forward or aft of the helm. On a cruising boat
this location clears the aft end of thecockpit forcrew members or
guests not needed for handling sheets. Neither the backstay nor
main sheet need interfere with the helmsman standing behind
the wheel, and the helmsman has sufficient room to brace his
feet without restriction. With the helm in mid-cockpit, winch
location does become critical, especially when installing wheel
steer in^ in an exist in^ cock~it where winch locations are fixed.
concentrating both winches and helm in the middle of the cockpit
can be most inconvenient for both helmsman and crew.
The forward cockpit installation places the helmsman close to
the companionway .under the protection of a dodger, out of the
way of winches and main sheet, and in a wide part of the boat
where head sails can be easily viewed.
,f~i)~ho~~ing the type of steerer is specifically covered on its
,_I , ppropriate page of this catalog, however, each has certain characteristics
which are best suited for a particular type boat.
Rack and Pinion Steering is most useful on boats from 16 to 40
feet where space under the cockpit floor is limited, or for those
small sailboats with transom hung rudders, such as the trailerable
models. The inboard rudder models that are particularly well
suited are those with the rudderpost coming through the aft
bridge deck, or the very aft part of the cockpit floor. The Rack and
Pinion can virtually be plugged into these set-ups with a mini-
mumamount of installation effort with the exception of building
a cover over the steerer to serve as a helm seat.
Worm Gear Steering is often referred to as "Non-Reversing".
meaning the feedback from the rudder will not normally turn
the wheel when the helmsman lets go of the wheel. These
steerers are most often used on traditional boats with aft raked
inboard rudders. Because of the rake, it is often impossible to
install a quadrant underthe cockpit floor. This type of steerer is
attached directly to the rudderpost above the cockpit floor at -
right angles to the rudderpost. The steerer shaft may be fitted
with a universal and an extra bearing to build in the exact wheel
angleforacomfortaljle helm. A wheel box must be built overthe
steerer to serve as a helm seat .This box can be kept as narrow as
possibleso the helmsman can sit behind oralong side the wheel.
The box can have a flip up top to serve as a seat back for long
watches at the wheel. Engine controls can be located right on the
sideof the helm seat within easy reach of the helmsman. Despite
the worm gear steerer being non-reversing, there are always
those boats with an exce~tional weather helm. or oarticularlv
hard steering. For these boats, we now offera fridtion 'shaft brak;
for all sizes of worm steerers.
Bulkhead Steerers are most advantageous for power boats,
motorsailers, two station steering Mid-Ship Cockpit boats, and
bridge deck console type steering stations, generally found on
custom racing boats. Bulkhead steerers can be purchased for
very small boats using direct sprocket and chain drive as well as
2:l and 3:l geared reduction sprocket and chain steerers for very
large commercial vessels, such as fishing boats and tug boats.
Pedestal Steering is well suited for both mid-ship cockpit and
aft cockpit boats with inboard rudders as well as transom hung
rudders. This system requires space under the cockpit floor for
mounting sheaves, sheave bracket, or Radial drive^^ Steering
System. It offers maximum flexibility in that any number of
sheaves may be mounted to route wire rope around engine
spaces, through aft cabins or around fuel tanks, etc.The pedestal
type system comprised of sprocket, chain and wire rope can be
used very efficiently for both cruising and racing boats up to 80
feet by varying the size of the steering wheel and the size of the
quadrant toeffectively changethe poweroutput necessaryto sail
your boat. This steerer is very popular and most versatile when
planning your cockpit for "convenience" accessories, such as
brake, guard, tables, instrument housings, engine controls,
helm seat and auto-pilot drives.
Pull-Pull Steering is a new system offered by Edson as an
alternative to a sheave and wire rope system. This System
can be used with either Bulkhead or Pedestal Steerers with
inboard or outboard rudder boats. It is most advantageous
for Mid-Ship Cockpit and Aft Cabin boats when routing the
steering cables from the Center Cockpit to the rudderpost
can become complicated.
The Pull-Pull System uses standard Edson components in
conjunction with flexible conduit housing 7x 19 stainless
steel wire rope. Unlike push-pull cables such as those used
on engine controls, pull-pull is always in tension. The result
is very positive steering control without the play and lost
motion generally associated with a Push-Pull Cable.
Each steering section of the catalog shows a chart for select-
ing the recommended size steering system for your boat. Each
chart is composed of information gathered from our many
years of leadership in marine steering. Due to the many varia-
tions in yacht design in areas of hull shape, engine horse-
power, and sail configuration, final recommendations must
be approved by your Naval Architect andlor,builder.
