Surviving a disaster at sea often centers on a couple of crucial decisions-- whether to abandon ship and when. It can be a crucial mistake to start survival procedures too late, but because your vessel is also your best shelter, abandoning it too early can also increase your peril. The decision to abandon ship hinges on a really critical question-- are you safer on your own vessel, however damaged or endangered, or trying to maneuver yourself and your crew into immersion suits and a relatively flimsy inflatable boat-- a life raft. In this program, we'll learn how to correctly stow and launch a life raft, how to board the life raft, right it if it capsizes, and stay together with shipmates while waiting to board. And we'll also show you what to do once on board the raft, including maintaining morale, signaling for help, and taking inventory of supplies. Life rafts are stowed in an easily accessible location and in a float free arrangement in case the boats sinks before you're able to launch it. The main things to be looking for is that the raft is readily accessible at any time, so you don't want to have a raft installed somewhere where it may be difficult to get to. The other main thing you want to be looking for is that the raft is installed in such a way that if it ends up being released by the hydrostatic release units-- so in case the crew wasn't able to actually launch it themselves-- that the raft doesn't float up and get entangled in any sort of beer gear or a mast or anything like this. So the location on the ship should be such that it's as free as possible for any obstructions that may be in the way of the raft deploying. The raft is contained in a rigid fiberglass canister. It rests in a cradle, and is held in place by a tie down strap attached to a hydrostatic release unit, which will release automatically if the vessel sinks suddenly. So I give myself some slack, and I'm going to come through here with a clove, right? And a half knot. To launch a raft manually, type the painter securely to the vessel before you throw the canister overboard. Release the securing straps using the quick release device, grasp the canister at both ends, and throw it into the water. The raft should be launched over the lee side, or it may be damaged by colliding with the vessel. Make sure the painter remains attached to the vessel. When it reaches its full length, it will trigger inflation. You may need to sharply tug the painter to activate inflation. Wait 15 to 20 seconds for full inflation. Your raft will probably over inflate and you'll hear escaping air, which is normal-- simply the CO2 cylinder emptying. We need to go back to land to identify the key features of life rafts. The raft is equipped with an emergency pack with all the regulatory required contents such as food, water, pyrotechnics, repair kits, pedals, et cetera. A Coast Guard approved life raft contains a considerable quantity of equipment and supplies. You should be aware of the rafts supplies and how to use. And it's useful to supplement the supplies on board the raft with additional gear and provisions. These may include the following-- blankets and extra clothing for warmth, foul weather and other waterproof gear such as plastic sheeting, an EPIRB and extra flares, extra water and high energy foods, a coil of light rope and light buckets for bailing, and personal survival kits for each crew member. If possible, you want to board the life raft without entering the water to avoid the cold shock and possible soaking. You may be able to jump from the rail directly into the canopy entrance or lower yourself to the raft with a ladder or net. Clear. If you must enter the water, do it as close to the raft as possible. It's hard to swim in an immersion suit, so stay in contact with the painter line. Jump from the lowest possible point and beware of hazards below you. Most newer life rafts our self-righting. If the raft has inverted, right it by means of the righting strap. Right it from the cylinder side where it says "right here" or the cylinder may injure you. Get into the raft as soon as possible. If you are delayed, do not swim aimlessly. Swimming increases heat loss. Remain as still as possible, using flotation to keep you high in the water. [ALARM] Use a whistle to notify others of your position. Form a group to be more easily located and huddle to forestall heat loss. Boarding a raft from the water without help can be difficult. Pull yourself in head first using the boarding ladder and lifelines at the raft entrance. Try to pull yourself up with the boarding ladder and lifelines rather than the canopy, which could be torn by your weight. Once on board, help others into the raft. Use the floating rescue ring located outside the entrance to assist others. Don't cut the painter connecting you to the vessel unless it's in danger of sinking. On-board the raft, close the canopy entrances and take immediate inventory of your supplies and the condition of your people. Treat any injuries and distribute medicines to allay sea sickness if necessary. Preserve body heat at all costs. Keep clothing dry and communicate with everyone. Try to maintain morale and establish routines, like watches, tasks, and distress signals. Secure the loose items from your survival kit so they do not go overboard. On large vessels like the Tacoma, you will most likely abandon ship on a life boat. But if you can't get to a life boat, a life raft will be your next alternative. With today's advances in signalling technology, rescues occur sooner than ever before. In this program, we learned some important elements of life raft use and maintenance, including how to store and launch the life raft, making sure it stays attached to the vessel in distress, how to board the life raft, as well as righting it if it capsizes, and how to safely approached the life raft while you wait your turn to board, and what to be aware of once you're in the life raft-- including communication and maintaining morale, preserving body heat, and taking inventory of supplies. If you do end up on a life raft, lash down your gear, post a watch, and take command of your new ship and situation. Your chances of survival will improve greatly.
