3. Reference Arm Angle. Adjustable reference arms
allow you to determine the apparent wind angle.
Three different detent positions are provided: 60°, 90°,
and 120°. The 90° position is a good angle to use for
general purpose sailing. The following guidelines may
allow you to set the angle more precisely:
• Upwind tacking in light winds: 75°–90°
• Upwind tacking in medium to heavy winds: 60°–75°
• Downwind tacking: Determine the best angle for
your situation through sailing trials and adjust the
Telo-Cat accordingly. Proper apparent wind angle is
very dependent on windspeed, boat speed, and
tacking angle.
To adjust between or beyond the stock angles, carefully bend with pliers as shown:
HOW TO ADJUST
1. Balance. The Telo-Cat is factory balanced and
needs no further adjustment.
2. Shaft Angle. Shaft should be 90° to water level.
Upwind
Downwind
If angle for your catamaran is not correct, carefully
clamp in a vice and bend as shown:

IMPORTANT: Install split ring in hole on shaft after
it has been positioned in the spring clip. The split ring
prevents the shaft from falling into the water if it
should vibrate loose.
