Propeller
Performance Testimonial
|
|
To
sum things up, I am impressed! You said that I would get improvements in
speed and vibration mid-range and top end and I am happy to report that
I have seen improvements right across the speed range. I picked 2.4
knots at my cruise speed and vibration was reduced by up to 40%, plus at
the top end I got another 1.7 knots. The Stainless Steel
"Wahoo" propellers
I fitted to my Riviera 4000 Offshore had improved the boat so markedly
that family and friends have commented on how much smoother the boat now
feels. I would have no problem recommending these propellers to any of
my boat-owning friends and will specify them as standard on any future
boat purchases!!
The top end speed is
exactly as the calculations predicted and these propellers have markedly
more "bite" when manoeuvring than the ones I replaced, even in reverse.
As a result, the boat runs better, cruises faster with less vibration
and gets on plane 200 rpm earlier, a real bonus when cruising offshore
in a decent swell.
Once again thanks to
Henleys Propellers and to Twin Disc Pacific for getting it right first time and giving me the extra
performance without the shake!.

Launch went well yesterday, we had the
Coastguard vessel next to us and they were going about 1 knot faster at
28 knots, then our engineer advised a short burst at wide open throttle.
Although the electronics had not been commissioned, we estimate approx
28-29 knots. The square planing board at the stern was actually on top
of the water due to our very light load. There was no prop aeration at
all which can sometimes happen with this hull shape as they are
reasonably close to the surface. If
I can offer some advise, when choosing propellers, do not just get the
cheap ones, both the Ferry and our Alaskan 41 have gone for specific
propellers from Henleys in New Zealand, who are the experts in this type
of full displacement hull shape. We work closely with Twin Disc who are
their Australian agents.

"Several of our clients have
now invested in Tiger Props, typically improving speeds across the range
by 1.5 to 2 knots. With this performance we have decided to fit the
Tiger Props as standard on all new contracts."

" Wherever possible we prefer to use Henleys Propellers as we have a lot of confidence in their product. We generally use Henleys Propellers on most of the boats we design for Australia and boats which are built in Asia. Henleys supply a good product and understand our vessels and how they perform which is critical to propeller design."

"Naiad has designed and
developed twin diesel shaft driven rigid hulled inflatables using complete
Henleys drive lines. Each time Henleys speed predictions and prop selection
have been accurate. It is most pleasurable when things go this well."

"Henleys suggested four blade
Tigers be fitted to our new Genesis 400 Targa, they were right on the
button. Better than predicted top end speed (33knts), really efficient and
smooth through to mid range cruise."

"On fitting tiger Props to our
planing launch we experienced a 2 knot speed increase through out the
engines RPM range. Manoeuvrability was significantly improved."

Tiger Props on our range of power and motor sailing catamarans as they
improve performance and economy."

"Its been four years since Salthouse
Marine changed to Henleys propellers exclusively. We were looking at
reducing noise and vibrations caused by propeller wash, as well as improving
performance and product consistency. The team at Henleys are great to work
with and have been extremely helpful in developing and improving our
product. Our results show their ability to work with us to get the best
result."

our latest Millennium design vessel the difference factor has been
extremely smooth running."
Dave Duke,

"On fitting 2 x 26" 4 blade Tigers to my new
Warwick 16 metre vessel we achieved a speed gain on the measured mile of
3.4 knots. As you can imagine I'm absolutely rapt."

"Tiger Propellers sell
themselves. My customers now demand them. Their reputation for quieter and
smoother running is to be believed."

"SkipJack
Propeller" Just a note to say thank
you for your prompt efficient service, the propeller fitted perfectly onto
the shaft and we are extremely happy with the performance it provides. We
can now comfortably reach hull speed with a power to spare. Sailing
performance is greatly improved with not noticeable effect of drag.
