Spars, Rigging, and Hardware for Sailboats
|Isomat's Isovang is a tubular Hard (solid)
Vang with integral sheaves and line that is Spring cushioned for Boom support. For
recommendations on a New Isovang for your boat, contact us with Boat
details including current Mast and Boom Sections.
Isomat has produced the Isovang in two (2) different sizes. Both
sizes have been produced in a variety of lengths. Sizes are
easily differentiated by tube diameter, or by the diameter of the integral sheaves. Should
you need parts for an existing Isovang, you'll need to measure one
of these items and determine which size Isovang you have. Click on your
Isovang size, below, for additional data and part numbers.
