Sailing ships were (and are) frequently put in the way of difficult conditions, whether by storm or combat, and the crew frequently called upon to cope with accidents, ranging from the parting of a single line to whole destruction of the rigging, and from running aground to fire.

[edit] Accidents to the steering
The sailboat is particularly vulnerable to capsizing or hitting a shoal or rock in the water when the steering fails. In heavy chop there is a lot of force on the rudder as it pushed by the water. If the ship is flying a Spinnaker and it loses steering, the boat will most likely broach (head up into wind), which will, on most boats, cause a capsize in heavy weather. It is possible to sail smaller dinghies without a rudder using only sail adjustment.
[edit] Cargo shift
On a ship cargo must be stowed evenly so that the ship sits upright. All ships are vulnerable to cargo shifting, causing the ship to develop a list to one side. However sailing ships are particularly vulnerable because the ship naturally heels over in reaction to the force of the wind on the sails. If the cargo is not adequately secured the cargo may fall to the leeward side of the ship. Loose cargos (e.g. grain) flow downhill like water if not adequately secured (e.g. by shifting boards) and are particularly prone to shifting. If a large quantity of cargo shifts the ship may develop such a heavy list that she capsizes. A catastrophic cargo shift caused the loss of the tall ship Pamir in 1957.

[edit] Capsize
The severity of a capsize depends on the size and design of a vessel. A small dinghy is designed to capsize and be righted by her crew. Yachts are typically built to right themselves even if heeled over beyond 90 degrees. However a large sailing ship will typically lose all stability at a smaller angle of heel, and will be vulnerable to downflooding and sinking if heeled beyond this point.
[edit] Fire
Fire is a serious threat to all ships, but to a ship made of wood, rope, and canvas, it was the greatest danger of all. Cooking fires in the galley were watched constantly, and put out instantly if the weather turned ugly, or an enemy ship appeared in the distance. Warships had an elaborate set of procedures for handling their gunpowder; the magazines were deep in the ship and the lanterns kept in another room, with a window between.
The introduction of steam power in the mid-1800s was attended by the use of "fire-engines" consisting of pumps and hoses. Even so, fire was fatal to a ship far more often than not.
