RUDDERSAFE DOBBELT-ROR for utenbordsmotorer
Problemer med at båten
"jager"?
RUDDERSAFE optimaliserer båtens retningsstabilitet i lave hastigheter på en
effektiv måte.
Ved større hastigheter løftes roret over vannflaten, slik at en unngår
overstyring og redusert fart.
Ruddersafe kommer i flere modeller: inn til 21´ - 28´ og over 28´.
Egne modeller for Volvo Penta 280/290

The
rudder for stern-drive and outboard-powered boats.
Optimum manoeuvrability and greatly improved directional stability at
low speeds.
Greatly improved steering at low speeds
At last there is a definitive, effective solution to the well-known
problem of poor manoeuvrability at low speeds that affects most
outboard-powered and stern-drive boats.
|
|
|
The dual rudder blades behind the propeller
provide additional steering capacity, which results in optimum
manoeuvrability, even with the engine switched off, both ahead
or astern.
In addition to surprisingly good steering, above all in marinas,
locks, narrow waterways and during manoeuvres to get into and
out of berths, Ruddersafe’s greatly
improved directional stability also helps to reduce fuel
consumption. |
|
|
|
With Ruddersafe you do not
need to make constant directional adjustments at low speeds,
which makes cruising more pleasant and relaxed. |
|
|
|
At high speeds the pressure on the two trim
planes lifts the two rudderblades out of the water, thus
avoiding oversteer and loss of speed.
An automatic spring mechanism returns the dual rudder to its
original position as soon as the speed and water pressure have
reduced. |
|
|
|
|
A further advantage of Ruddersafe is the
protection it provides when going astern. This prevents
propeller damage and reduces to a minimum the risk of bathers
coming into contact with the propeller. |
|
|
|
The dual rudder can be attached to the engine
cavitation plate without the need for any special tools or for
the drilling of holes. |
|
|
|
Ruddersafe's
corrosion-resistant, rustproof materials require only minimal
maintenance. Lubrication of the tilting mechanism during normal
engine maintenance is adequate to ensure many years of
problem-free sailing. |

Outboard Rudder
Attachments
|
|
Following a discussion on our forum regarding directional stability with
outboards, we decided to publish this gallery entry for anyone thinking
about 'rudder attachments'. There are a number of commercial products
available, (some no longer produced),
The
most sophisticated commercial product available is the Dutch made
'Ruddersafe' which is suitable for both displacement boats and
high speed planing boats. This clever design allows the twin blades to
automatically lift up out of the propellor slipstream when the boat is
travelling fast, as otherwise they could turn the boat too sharply.
At
displacement speeds, most outboard boats have rather 'vague' steering,
requiring constant minor steering corrections. The addition of a rudder
blade behind the prop makes things much more precise, often transforming
the handling. Also, when fitted, they give the boat steerage way even
with the power 'off' while still moving, unlike most bare outboard legs.
The
Ruddersafe is available in three sizes (according to the size of boat),
and is supplied as a complete set of parts which can be fitted to any
make of outboard motor without needing to drill any holes.

at 07:57 Hi Clive,
Yes, it was a "Ruddersafe", which I found transformed the handling
of the boat.Just read your post about this ruddersafe on the
handrails thread and wanted to know a little more about them. Do
they affect the speed or response of the steering while planing? Are
they hard to fit and where do you get them? |

| Hi Adrian, No, there's no problems with them when planing.
They're cleverly designed to automatically pivot up out of the
slipstream of the prop so as to not cause drag when planing above a
certain speed, so I noticed no difference at all when doing 20mph
plus, the handling was exactly the same as with the bare leg.
If it didn't lift out of the way at anything above displacment
speeds, the enhanced steering ability would make the handling
dangerous, making the boat too responsive, and allowing it too turn
too quickly.
It was easy to fit as long as the boat was either on a trailer or
backed up to a slipway, as there's lots of nuts and bolts that you
can easily drop in the water ! No need to drill any holes in the
outboard at all.
Everyone that I've talked into buying one has been happy with the
result, transforming the handling of their boat at displacement
speeds,(famous last words...)
