Releasing mechanisms:
ON load Mechanism:
On load mechanism can release the life boat form the wire, above the water level and with all crew members inside the boat.
The load will be still on the falls as the boat would not have touched the water. Normally the height of about 1m is kept for the on load release, so that the fall is smooth without damaging the boat and harming the crew inside.
A lever is provided inside the boat to operate this mechanism. as the lever is operated from inside, it is safe to free the boat without going of the out of life boat, when there is a fire on the ship.
OFF load Mechanism:-
The off load mechanism releases the boat after the load of the boat is transferred to water or the boat has been lowered fully into the sea.
When the boat touches the surface of the water, the load of the fall and hence the hook releases and due to this mechanism the hook detaches from the fall. If the detachment does not takes place, any of the crew member can remove the hook from the fall.
(2) Stabilizing pocket
(3) Insulated canopy have Two layer.
(b) Now fasten it to ship side on deck and make sure it should not be loose.
(c) Now remove railing and clear the way for launch.
(d) Unfasten the ship hook from cradle,
(e) Two person will lift raft container from its cradle and thrown it to overboard ( make sure painter point will be ship side)
(f) Now after thrown take out remaining painter from raft and after that give sharp pull, but until the raft inflate ( Regulation says that it will inflate within 1 to 3 min depend on ambient temp )
(g) Now with the help of same painter pull it to ship side,
(h) Now lower the embarkation ladder or if height will low than jump into water, you can direct jump into raft if the height will not be more than 4.5 m from water line, and also by using embarkation ladder you can go down and jump it inside, or swim some distance and climb up in raft.( but if you are in cold weather try not to get wet, keep dry as possible as you can.)
(i) You must have to sit in order wise means face by face, to not be unbalance of raft,
(j) Have to take SART and EPIRB along with you.
(k) After all person get inside head count must be taken,
(l) Now immediately cut the painter by using knife, and using paddle or sea anchor get clear the ship because as ship will start to sink there will be low pressure create in water near by area of ship.
(b) It will cut the securing rope around the canister or container of the raft, and now raft will float free.
(c) Now ship will further sink, the painter line will stretched and it will inflate the raft.
(d) Now due to increase in buoyancy will break the Red weak link around 2.2 KN± 0.4 and life raft will be on surface of water now.
NOTE: life raft located in forward will be only inflate manually, it don’t have H.R.U and its person carrying capacity also 6 person, and life raft located in midship means at embarkation station it have maximum capacity and can be launched by manually, by davit and by H.R.U. So these are the main difference between fwd and aft life raft.
(b) First you remove ship’s hand rail or gate.
(c) Unlash the container for launch, REMEMBER INBOARD mark should be ship side.
(d) Lower davit hook and make it lock with lifting shackle.
(e) Secure canister or container lines outboard.
(f) Secure bowsing line.
(g) Pull out approx 5-6 meter of painter line.
(h) Make sure before lifting that hook and brake lanyard are inboard.
(i) Secure painter line.
(j) Now pull full length of painter.
(k) Now lift the life raft canister upto some height.
(l) Now pull the painter and give sharp pull to inflate life raft.
(n) Make sure the opening of canopy means access should be ship side.
(o) Now secure the life raft.
(p) Now one person will go inside to make some check ( make sure you should not wear Sharpe edge shoes or heels )
(q) Collect SART and EPIRB.
(r) Now go inside life raft and seat evenly.
(s) Now release bowsing line and pass to raft.
(t) Check launching area is clear.
(u) Lower the raft using brake release.
(v) You can operate hook release 1 m above the water or allow the raft to touch the water and load will reduce from hook and it will release it self.
(w) Now cut painter and use sea anchor or paddle to clear the area immediately.

(c) Now remove railing and clear the way for launch.
(d) Unfasten the ship hook from cradle,
(e) Two person will lift raft container from its cradle and thrown it to overboard ( make sure painter point will be ship side)
(f) Now after thrown take out remaining painter from raft and after that give sharp pull, but until the raft inflate ( Regulation says that it will inflate within 1 to 3 min depend on ambient temp )

(a) Launching life raft by davit make sure always you keep maintaining davit mechanism.(b) First you remove ship’s hand rail or gate.
(c) Unlash the container for launch, REMEMBER INBOARD mark should be ship side.
(d) Lower davit hook and make it lock with lifting shackle.
(e) Secure canister or container lines outboard.
(f) Secure bowsing line.
(g) Pull out approx 5-6 meter of painter line.
(h) Make sure before lifting that hook and brake lanyard are inboard.
(i) Secure painter line.

(n) Make sure the opening of canopy means access should be ship side.
(o) Now secure the life raft.
(p) Now one person will go inside to make some check ( make sure you should not wear Sharpe edge shoes or heels )
(q) Collect SART and EPIRB.
(r) Now go inside life raft and seat evenly.
(s) Now release bowsing line and pass to raft.
(t) Check launching area is clear.
(u) Lower the raft using brake release.
(v) You can operate hook release 1 m above the water or allow the raft to touch the water and load will reduce from hook and it will release it self.
