(u) 6 doses of anti-seasickness medicine and a seasickness bag for each
person the life-raft is permitted to accommodate.
(v) instructions on how to survive;

Float-free arrangements for life-rafts:
a) Painter system
The life-raft painter system must provide a connection between the ship and
the life-raft and must be so arranged as to ensure that the life-raft when released
and, in the case of an inflatable life-raft, inflated is not dragged under by the
sinking ship.
b) Weak link
If a weak link is used in the float-free arrangement, it must:
(a) not be broken by the force required to pull the painter from the
life-raft container;
(b) if applicable, be of sufficient strength to permit the inflation of the
life-raft; and
(c) break under a strain of 2.2 +/- 0.4 Kilo Newton.
4.2.4 Hydrostatic release unit
If a hydrostatic release unit is used in the float-free arrangements, it must:
(a) be constructed of compatible materials so as to prevent
malfunction of the unit. Galvanizing or other forms of metallic coating on parts of
the hydrostatic release unit is not acceptable;
(b) automatically release the life-raft at a depth of not more than 4
meters;
(c) have drains to prevent the accumulation of water in the
hydrostatic chamber when the unit is in its normal position;
(d) be so constructed as to prevent release when seas wash over
the unit;
(e) be permanently marked on its exterior with its type and serial
number;
(f) be permanently marked on the unit or identification plate securely
attached to the unit stating the date of manufacture, type and serial number and
whether the unit is suitable for use with a life raft with a capacity of more than 25
persons;
(g) be such that each part connected to the painter system has a
