The topping lift indicated Topping lift on a US Yachts US 22 sailboat. The topping lift (more rarely known as an uphaul) is a line which applies upward force on a boom on a sailboat. Part of the running rigging, topping lifts are primarily used to hold a boom up when the sail is lowered. [1]
The boat was at one time supported by a class club, the ETAP Owners Association. [6] A 2009 review in Yachting Monthly stated, "the largest of the lifting-keel Etaps, launched in 1981, the 26 manages a proper heads compartment amidships and an inboard engine powering a saildrive. She is designed to right herself with the keel fully up, but many ...
The tensioned portion of the rope would fasten the ship to the quay, hoist a foresail, lift a spar into position on the mast or be used to transfer cargo to or from a dock or lighter. A capstan is a vertical- axled rotating machine developed for use on sailing ships to multiply the pulling force of sailors when hauling ropes, cables , and hawsers .
A portable boat lift is not a boat lift which is commonly found attached to a dock. Although some devices allow one person to separate a boat from a trailer or lift a boat up and out of the water, they are not by definition portable. The term "boat lift" originally referred to lift locks. In modern usage the term "boat lift," as opposed to ...
A trailer sailer is a type of sailboat that has been designed to be easily transported using a boat trailer towed by an automobile. They are generally larger than a sailing dinghy . [ 1 ] [ 2 ] Trailer sailers include day sailers and small cabin cruisers, suitable for living on.
While under sail, the opposite force to the vang is supplied by the sail itself. When the sail is furled, a topping lift supplies the upward force on the boom. Some line vang systems incorporate a piston to provide the topping lift force and to damp oscillations. Hydraulic vangs can inherently act in the topping lift role.
For this reason, it is not uncommon to find boats with a combination of shallow keel and centreboard (e.g. Randmeer). The keel provides the housing for the centreboard, moving it out of the hull, but adds only a small amount of draft to the boat. The centreboard can then be lowered in deeper waters to increase the amount of lift.
Left-hand boat: Down wind with stalled airflow— predominant drag component propels the boat with little heeling moment. Right-hand boat: Up wind (close-hauled) with attached airflow—predominant lift component both propels the boat and contributes to heel. Points of sail (and predominant sail force component for a displacement sailboat).
