1. Q.
What is the Tiger Shark VG Hydrofoil?
A. It is a pair of fins that
fit either side of the cavitation plate on any
outboard motor or stern drive and provides lift to the stern and keeps the boat
at planing angle at much lower speed.
2. Q.
How does it work?
A. Shaped just like an
aircraft wing (in fact designed by a leading aerospace engineer), the Tiger
Shark VG hydrofoil provides increased pressure to the underside and reduced
pressure on the upper surface of the wings giving tremendous lift force.
3. Q.What size of motor will it work on?
A.The
Tiger Shark VG can be installed on motor sizes from 5hp up to the maximum outboard or stern drive available and
is suitable for all types of planning hulls.
4. Q.
Will the Tiger Shark VG increase my top end speed?
A. Unless you have a severe
problem getting on plane it will probably not increase your top speed.
Although some users report an increase in their top speed that is a welcome but
not normally expected outcome.
5. Q.
Will this extra lift force damage my motor or drive?
A.
No. In fact the extra lift means your motor and drive train will not have as
much strain placed on it in getting the boat on the plane.
6. Q.
What do the VG's do?
A. The VG's (or vortex generators), just like the newest aircraft
have on their wings, the patented shark tooth shapes (where we get our name)
spin the water as it passes over forcing it to hug the wings. This
prevents "flow separation" (common with ordinary hydrofoils),
increases lift, and reduces drag.
7. Q.
Will the Tiger Shark VG improve rough water handling?
A. Yes, You will notice a marked
improvement in comfort and handling in rough water.
8. Q.
Will the Tiger Shark VG save me money?
A. Yes by saving fuel and
reducing power and drive wear. Depending on motor size, and how often you
use your boat, the Tiger Shark will pay for itself in a season or even within a
weekend.
9. Q.
What other benefits will I get with a Tiger Shark VG?
A. All hulls will notice a
dramatic reduction in noise level. This is due to the shielding of noise
from the prop tips by the Tiger Shark VG. You will also find you can tilt
the motor up higher in shallow water without sucking air. All planing hulls will plane quicker and at lower speeds.
All hulls will handle much better at slow speed and with the additional safety
of improved forward visibility. Eliminates slide out in tight
turns. Skiers will notice a far more even pull, even in tight turns (one
of Australia's leading ski shows tried Tiger Shark on one boat, and were so
impressed they now have them fitted to all boats). Ski learners will
appreciate the lower tow speeds that can be maintained. Hole
shot improved by at least 50%. Tiger Shark VG can eliminate or reduce the
following problems: Porpoising, chine
walking, cavitation, and excessive wake.
10. Q.
What happens if I am unhappy with my Tiger Shark VG?
A. We are so confident that
you will be more than happy with your Tiger Shark VG that we give a full money
back guarantee. Simply return, within 30 days, with proof of purchase, to
the retailer you purchased from and get your money back
11. Q.
Is the Tiger Shark VG available in white or gray?
A.
The Tiger Shark VG, like the old Model T Ford, is available in any color
you want as long as it is black.
12. Q. From what material is the Tiger Shark
manufactured?
A.
Tiger Sharks are molded from tough polypropylene.
13. Q.
What are the dimensions of each wing?
A.
Each wing measures 9.5” x 8” (11” on the “delta”
side). The thickness varies from ¾”
to about ½”.
