Frequently Asked Questions:

 

 

 

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”.
