What information is needed to determine the correct size on a boom vang order?
Please contact any Navtec agent for a vang sizing data sheet, or use our online vang sizing calculator. You will need to know E, P, weight of boom and weight of mainsail along with the placement of the boom vang lug and mast vang lug relative to the gooseneck in order to fill out the sheet. Once the sheet is completed Navtec will recommend a vang size.
