You are berthed alongside stb side.onshore wind. you have a ship 25m forward and 25m aft berthed. how will you cast off ? no tug
1. Single up to a spring line F and A
2. Slack fwd spring, Hard port, kick ahead.
3. vl will swing to port, the onshore will wind will help by acting more on the accommodation block.
4. Once the vl ahead comes on stbd bow, let go all lines, mid ship rudder, dead slow ahead and come out clear.
Note- In the single up position the vl is safely held by the spring lines since they provide the largest proportion of longitudinal restraint and the onshore wind keeps the vl alongside.
Mariners who passed said that they will give a short kick with Port Rudder, let it swing a little port and a little ahead, drop port anchor to stop onshore drift and then Astern kick to clear ...While Capt menon was not very happy with this but he agreed to it.

let go all lines fwd aft except aft aft springs and 1 breast line. give shot kick ahd andwith rudder hard stbd.when bow clears well from vsl ahd. then let all lines aft, with on shore wind stern will move to stbd. and with ahd and stbd movement vsl can cast off easily. bt if wind speed is very high donotunberth till wind subsides.
Make sure all shore cranes and gantries have been cleared away from ur shipside.Cast of all lines aft, keep only 1 headline and 1 fwd spring. make sure ur springline is tight(this can be done by heaving ur headline) and give a kick ahead. This will cause an effect of moving the stern out and the bow will close in towards the berth. A close watch must be kept on ur bulbous bow. When ur stern has moved out sufficiently,give a stern movement and simultaneously cast off all lines. Give a stbd helm while doing so, so as to counter the transverse thrust.
