They were both located off the deck and lowering them required a piece of equipment held in the boatswain's store in the bow. By the time this was realised, the bow was already well underwater and the store was inaccessible. They were manhandled down and floated away freely as the deck flooded. The lifeboats were intended to be launched from davits supplied by the Welin Davit & Engineering Company of London. All lifeboats but the collapsibles"
"Davit A davit is any of various crane-like devices used on a ship for supporting, raising, and lowering equipment such as boats and anchors. The term sometimes refers to structural arms in other applications where a suspended load is supported in similar fashion to the naval application. Davit systems are most often used to lower an emergency lifeboat to the embarkation level to be boarded. Davits can also be used as man-overboard safety devices to retrieve personnel from the water. The lifeboat davit has falls (now made of wire, historically of manila rope) that are used to lower the lifeboat"

It was balanced so that it would right itself if it overturned—all subsequent airborne lifeboats were given this feature. When it hit the water the parachutes were jettisoned and rockets launched lifelines. Coamings were inflated on the descent to give it self-righting.

Some modern lifebuoys are fitted with one or more seawater-activated lights, to aid rescue at night.

The most common downhaul on a modern sailboat is attached to the spinnaker pole, though this may be referred to as the foreguy in some rigging nomenclature. The term is also commonly applied to the cunningham on the mainsail. In a windsurfing rig, the downhaul is the primary load-bearing line which controls the sail's shape.

It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, inflatable or rigid-inflatable combination hulled vessels. There are generally three types of boat, in-land (used on lakes and rivers), in-shore (used closer to shore) and off-shore (into deeper waters and further out to sea). A rescue lifeboat is a boat designed with specialised features for searching for, rescuing and saving the lives of people in peril at"

They typically use bait or a light-source as a fish-attractor. Lift nets are also sometimes called ""dip nets"", though that term applies more accurately to hand nets. Portable hand lift nets are small lift nets operated manually. They usually have a rigid frame which is"
