Seatorque Control Systems in now a USA
Distributor for QuicKutter™ Rope Cutters by
Quickwater Marine.
This new design of rope and debris cutter represents
a significant improvement over all other rope
cutting devices. In four years of UK fittings only
two have required spare parts. Many are on
commercial craft from fast fishing cats to ferries,
as well as performance leisure and recreational
craft.
QuicKutterTM Rope Cutters are
a breakthrough in rope cutter design.

How does a QuicKutter work for traditional shaft
installations?
Debris is caught by the rotating blades of your
prop, the debris is then wrapped with every turn of
the shaft first around the hub of the propeller (if
there is one) and then around the shaft until it
meets the bearing carrier (stern tube or P bracket)
as the engine now tries to force more debris with
every turn into this gap the forces try to pull the
shaft back as the debris pushes on the prop. In
extreme circumstances usually with large engines
when the effects of the debris are not noticed by
the skipper in the form of a drop in engine rev's
whole gearboxes have been separated from engines, or
struts torn out of the bottom of the vessel.
The QuicKutter utilizes this force to push the
debris against a fixed blade angled so that it
shaves through strand by strand. Hardened versions
have cut through 5mm S/S wire as they break strand
by strand. The Spool is an integral part of the
cutter in that debris can not reach the bearing
carrier without first meeting the cutter blade.
The three images below show first the line wrapped
tightly, caught by a Prop blade, and already being
pushed against the sharp edge of the cutter, in the
second image the cutter has shaved through one
strand of the three stranded rope, in the last image
the rope parts. In practice this happens in an
instant, and ideally we locate the cutter quite
close to the prop (25-40mm) so that debris is cut
quickly.
Ropes are always drawn tightly across the blades.
The blades will not bend or break and can not jam.
No evidence of cavitation to date, No bearings, No
anodes, No shock loads as debris meets the blades.
Entanglement is always lurking for powered vessels
that voyage through fishing grounds. Rogue rope,
rope attached at one end with a float and the other
to a fish trap or crab pot, net, line, plastic
sheet, weed and other floating debris can all catch
the vessel’s propeller.
