Different categories of sails are [[Reefing|reefed]] (reduced in size) in different manners and therefore have different fixtures that achieve shortening of sail. Traditional canvas square and gaff-rigged sails have one or more rows of ''reefing lines'' that pass through the sail, which reach around the sail that has been gathered in to reduce its size and secure the remaining unreefed sail to the spar (square rig) or boom (gaff rig).<ref name = Hahne/> Gaff-rigged sails require an extra set of lines to secure the part of the leech that becomes the new clew. These are called ''reef pendents'' that drop through a ''comb'' on the boom, where they are secured, as needed.<ref name = Cunliffe >

Mainsails on Bermuda rigs typically have paired grommets that secure the luff and leech to the boom, as the sail is lowered to reduce its area. These become the new tack and clew. A reefing line typically runs through the reef point on the luff to quickly secure the new clew. The grommet that becomes the new tack is typically hooked onto the boom. There may be grommets along the line between the new tack and clew that allow ties to pass through around the boom.<ref name = Hahne>
