Great Hawk Wind Indicator
 
Suitable for Cruisng and Racing Yachts up to 20m.
 
The key to good boat speed using the Great Hawk is getting the reference arms correctly set up. Please see the Hawk above. The benefit of the Great Hawk is that it comes with different Locking Block Pieces that Lock the Reference Arms at preset angles. 55, 60 and 65 degrees. We would suggest 55 degrees for racing boats and 65 degrees for cruising boats. 60 degrees is in the middle for Cruiser/Racers.

Once you have set the Great Hawk up, it needs to be positioned on the top of the mast in a position you can see it from the cockpit and with the Reference Arms equal distance either side of the centre line. This can be done in the Boat Yard before the mast is stepped, but so often the aerials and Hawks get knocked by the lifting slings etc. If this fails you will need to send somebody up the mast with a small screw driver. The simple method is to loosen the screw in the Locking Block and rotate it slightly until the alignment is good.

Now you can use the Reference Arms with the back of the Vane Arm to judge your pointing angles upwind or with the front of your Vane Arm to judge your gybing angles downwind.

New for the Great Hawk in 2007 is the Mast Crane adaptor. Most Yacht Masts have a Crane or plate at the top for external Halyards which have predrilled holes in them to connect Antennas and lights etc. The new adaptor bolts straight into one of these holes and then allows you to screw the Great Hawk Mast Clamp into the adaptor and saves having to drill any holes in the mast. See the photos.
