STRONG LIKE BULL.
Sailors often worry about sail and line chafe; they're one of the biggest enemies on any boat. Several anti-chafe products are available, but only Dynaglide Ultra has an abrasive quality that is stronger than steel, yet it is thin enough to conform to halyards, sheets, stays, batten ends, dock lines and centerboards.
This tape has a thickness of just .007 inches (6.5 mil.), UV resistance/color in black. Available in greater thickness for heavy wear applications, such as anchor rode exits. Available in 10 yard (30 foot) rolls in four different widths (1 in., 2 in., 3 in. & 4 in.).
