Ordering Vang-Master
Standard Vang-Master rigid vangs are available for boats with vang fittings on the 
boom and mastbase. If your boat is not equipped with vang fittings, or if fitting width 
or pin diameter will not fit jaw and pin sizes listed in the chart on previous page, 
contact Harken Tech Services for information on a custom vang.
Determine Vang Size
Vang-Master sizes are based on boat sailplan and PCLC /PCLO dimensions 
(PCLC= distance between the center of unit mounting pins at mast and boom 
with unit completely closed. PCLO=distance between the center of unit mounting
pins with unit completely open.)
For PCLC, measure distance between hole centers with the boom at an attitude 
below which you never want it to go. 
For PCLO, measure the distance between these holes with the boom as high as 
you would ever want it to go.
Select the correct unit size using from the “Typical Boat Length” Chart 
Select the stroke size that fits your range from the “Pin Length/Stroke” Chart
Typical Boat Lengths:
VM1 & VM2: 5.5 - 7.9 m (18' - 26')
VM3 & VM4:  7.6 - 11 m (25' - 36')
VM5 & VM6: 10.7 - 14 m (35' - 46')
VM7 & VM8: 13.7 - 17.1 m (45' - 56')
