The "Mako" is a stainless steel surface propeller.
It offers performance and durability that exceeds traditional bronze
surface propellers. Manufactured in 4,5 and 6 blades with standard blade
areas from 0.6 to 1.1 ratio, incorporating skew and rake as required.
Finished to ISO484/2 Class S standard. Available
up to 33" diameter.

The "Barracuda" is a bronze surface propeller
that has been
fitted to a variety of surface drives either fixed type
or articulated e.g. "Arneson". The Barracuda has
many different profiles and cup sizing to best suit a
particular application. We have used this design
successfully in tunnels. Manufactured in 4,5 & 6
blades with standard blade areas from 0.6 to 1.1 ratio, incorporating
skew and rake as required.
Standard sizes
available up to 45” diameter in Nibral. Built to ISO484/2 Class S Standards.

The
"Wahoo" is a Stainless Steel
High Skew design. It offers performance, smoothness and
durability that exceeds traditional bronze designs. The Wahoo is revered
for its "back-up" ability. Manufactured in 4
and 5 blades, sizes from 17" to 33" and built to ISO484/2
Class S standards.

The Big Eye propeller
has a "marine formulated hard
chromed finish" over bronze. This chrome finish has
proven very popular with game fishermen while also offering good
antifouling and hard wearing qualities. This design
incorporates medium skew and rake. Manufactured in 4 blades, sizes
from 17" to 35" and built to ISO484/2 Class 1 standards.

The Tiger propeller is the most
common type of bronze propeller that Henleys
supply. The concept is linked to US Submarine Propeller
Design. Its highly skewed profile gives exceptional
smoothness and maneuverability especially in reverse, in comparison to more
traditional style propellers. During trials, this type of propeller was found to perform better in the mid and top
speed range of the vessels tested. Large savings in fuel
consumption have also been documented. Manufactured in 3,
4, 5 & 6 blades, sizes from 17" to 45" and built to
ISO484/2 Class 1 standards.

propellers were supplied:

The Yellow Fin is a
high performance bronze propeller that incorporates medium skew with rake. The
Yellow Fin is used in situations
where "lift" is seen to benefit a particular vessel. This prop
will run softer than conventional designs. Manufactured in 4 and 5
blades, sizes from 17" up to 45" and built to ISO484/2 Class 1
standards.

Black Tip - A
great combination!
The Black Tip propeller
has refined cord section with blade cup. It is a propeller that is
used for both displacement and planing hulls. New Zealand's top game
fishing vessel "Prime Time" currently runs "Black Tip"
propellers. Standard
sizes available up to 47” diameter in Manganese and Nibral. This type of propeller is made
in 3, 4 and 5 bladed versions. Blade area range from .55 to 1.05 B.A.R. Built to ISO484/2 Class 1 Standards.

The Skip Jack propeller
is designed for yachts.
The blade area of these propellers is not very large, 0.38 B.A.R. The propeller should be locked in position when
sailing to achieve minimum drag. Our own tests have shown
that on cruising yachts the effect on performance when
sailing is very difficult to quantify as it is so small.
You can do your own trial by cutting out a circle that
represents the prop diameter and taking .38 of that
circle as the presented area – convert this into a
tin can and go for a sail. At different speeds throw the
attached can over the stern and see if you can read any
drop on your log. Standard sizes available up to 38”
diameter Built to ISO484/2 Class 2 in Manganese Bronze or Marine Grade
Aluminum for Sail drives and Ali hulls.

Groper propellers are
made to suit a specified Nozzle. Available in either 3, 4 or 5 blade
versions. The advantage of running in a nozzle is one of
increased efficiency. The Groper propeller is used on
workboats such as trawlers and barges. We also offer this design in a
Skewed version.
Available in Manganese and
Nibral up to 47” diameter in ISO484/2 CLASS 1 or Class 2.

Flex-O-Fold
folding propellers have the most efficient blade profile available for
any folding or feathering prop. This means the more thrust when you have
to pound against wind and waves, less fuel consumption and smooth
operation.
The Flex-O-Fold is also the lowest drag you can
buy. This means you'll be able to expand your cruising horizons, get
home first or find the perfect moorings. Plus, you'll be much less
likely to catch a pot or other stray line.

Controllable
Pitch
Propellers-The CP
propeller is the ideal propeller for all cruising sailers and motor
sailers; and , theoretically* also for all motor yachts. It optimally
transfers the power to the water since it fully uses the available power
along the full-load line.

and Commercial Boats to which Henleys
Propellers have supplied these propellers. |
|
Except for those prefabricated propellers which
Henleys distribute, a detailed propeller drawing
is provided to our customers in order to give them an idea on what will
be the profile of their custom made propeller. Henleys will specify one of these
custom designs to suit your vessel.

Why
should you choose Henleys Propellers?
Data used for prop selection is supplied by our
customer on a Propeller Specification Form.
This information is firstly compared to Henleys vast database of proven
designs, and then entered into intricate computer software programmes
insuring the best possible selection for the customer. We then use this propeller selection in a Propeller Drawing Program
which is a parametric design/drafting tool for the preparation of
detailed and dimensioned propeller drawings. The designs made with the
use of this equipment are then transformed into patterns, castings and a
personalised set of "custom built" boat propeller.
To ensure the propeller design is maintained and
that the propeller is manufactured in conformity with ISO 484/2 Class 2,
1 or S standards, Henleys have invested in Electronic Propeller Scanning
equipment. This allows us to measure a propeller and to produce reports
on the quality of the propeller to a set standard.
This gives Henleys a distinctive advantage over
others, as we are able to control the design, manufacture and the after
care of Henleys propellers.
Henleys is also involved in a worldwide
network of propeller technicians operating similar equipment, to
whom we will be able to forward your propeller data and they would be
able to extend the Henleys care you deserve.
