*Barber haulers, which adjust the spinnaker/jib sheeting angle by pulling the sheet/sail inboard or outboard at right angles to the sheet. Consists of  either a ring or clip on the sheet attached to cordage which is secured and adjusted via fairlead and cam cleat.<ref name = Schweer>

* [[Boom vang|Kicking straps / boom vangs]], which control a boom-footed sail's leech tension by exerting downward force mid-boom. Normally this is a system of highly geared blocks, of flexible stainless steel wire and low stretch cordage but recently some sail boats have a short spar instead, often of carbon fibre. When sailing downwind the kicking strap (kicker) is tensioned to stop the boom lifting.<ref name=HowardDoane/>
* [[Cunningham (sailing)|Cunningham]]s, which tighten the luff of a boom-footed sail by pulling downward on a cringle in the luff of a mainsail above the tack. The idea is to flatten the main sail in heavier weather or when sailing to windward. In its simplest form a stainless steel hook that goes through the cringle. From the hook a cordage tail passes through a turnblock on the deck at the base of the mast and back to a cleat on the deck. Often the tail is split so the cunningham can be operated from either sidedeck in a racing dinghy.<ref name = HomeEvans/>
* [[Downhaul]]s, which lower a sail or a yard, and can be used to adjust the tension on the luff of a sail.<ref name=HowardDoane/>
* [[Outhaul]]s, which control the foot tension of a boom-footed sail. This is one of the main controls for sail fullness. In a racing boat the boom outhaul runs from the sail clew through a turning block along the inside of the boom and out through another turning block at the fore end of the boom. For simplicity many small racing craft have the boom outhaul attached to a powerful hyfield lever mounted on the boom or deck. The lever is let off for down wind sailing, so the main sail becomes full. Alternatively the outhaul tail can be attached to a block and tackle system so that it can be adjusted to many positions.<ref name=HowardDoane/>
* Jib [[Fairlead]]s, which determine the sheeting angle, depth of the sail, height of the clew, leach tension and other sail trim variables.<ref>Sailtrim 101, Sailing Magazine, 27 July 2008,  Retrieved 2 October 2024, https://sailingmagazine.net/article-17-sail-trim-101.html,</ref>
