Rig tune and maintenance are frequently referenced in the racing world, but sometimes can intimidate cruisers and weekend warriors. Usually the rig is ready-to-sail on new boats, and it often goes untouched for a long time after that. Eventually, however, rigging and fittings can settle in and stretch, or worse, vibrate and become loose. This can affect furling systems, sail shape, and rig tension. It can also lead to damage or low performance in any of those areas. A loose rig is much more dangerous and potentially damaging to a cruiser than an over-tight rig.
