The Harken 5:1 boom vang is standard on the daysailing rigged Flying Scots. It includes 29mm Carbo Harken blocks, cleat, and line. The kit does not include the vang bridle, bridle block or car, hook, or shackle. If your boat has a vang car you will need to order a twist shackle (170260). If you need any of these items they are linked to below. If you are interested in racing your Flying Scot you may want to consider the 12:1 cascading vang which is the standard on the race rigged Flying Scots. The link for the racing vang is below.
