Self-righting partially enclosed lifeboats shall comply with all up mentioned
requirements and in addition shall comply with the following requirements:
Enclosure
- every self righting partially enclosed lifeboat shall be provided with
permanently attached rigid covers extending over not less than 20% of the length
from the stem and not less than 20% of the length from the aftermost part of the
lifeboat.
The rigid covers required shall form two shelters which shall:
- if they have bulkheads, have openings of sufficient size to permit easy
access by persons, each wearing an immersion suit; and,
- be of sufficient interior height to permit persons easy access to their
seats in the bow or stern of the lifeboat.
The rigid covers shall be so arranged that they include windows or
translucent panels to admit sufficient daylight to the inside of the lifeboat with the
openings and canopies closed so as to make artificial light unnecessary.
The rigid covers shall have railings attached to the outside of them to
provide a secure handhold for persons moving about the exterior of the lifeboat.
Open parts of the lifeboat shall be fitted with a permanently attached
folding canopy so arranged that it can be easily erected by not more than 2
persons in not more than 2 minutes and insulated to protect the occupants
against heat and cold by means of not less than 2 layers of material separated by
an air gap or other equally efficient means.
The enclosure formed by the rigid cover and canopy shall be so arranged:
- as to allow launching and recovery operations to be performed without
any occupant having to leave the enclosure;
- that it has entrances at both ends and on each side, provided with
efficient adjustable closing arrangements which can be easily and quickly opened
and closed from the inside or outside so as to permit ventilation, but exclude
seawater, wind and cold;
- means shall be provided for holding the entrances securely in the open
and closed positions;
- that with the canopy erected and with the entrances closed, sufficient
air is admitted for the occupants at all times;
- it has means for the collection of rainwater;
- that the exterior of the rigid covers and canopy and the interior of that
part of the lifeboat covered by the canopy is of a highly visible color. The interior
of the shelters shall be of a color which does not cause discomfort to the
occupants; and
