Item: BMI R-CLOTH Vendor Num: CLO7532X50 Most wooden boats require some woven cloth and perhaps tape. Wooden boats which use molded chine construction greatly benefit from the use of biaxial tape. Composite-cored boat builders use non-woven biaxial, triaxial, or unidirectional cloth for their hulls. Tapes and cloths have a selvedged edge so the edges don €™t get stringy or fray. Cloth rolls have a nominal length of 125 yards, but may vary.
