Final answer:
The dimensions of the material and grommet position for an inspection data pocket for a life raft carrying case are not specified in the question, and such information would typically come from the case's design specification.
Step-by-step explanation:
The question regarding the manufacture of an inspection data pocket for a life raft carrying case seems to be missing specific details related to the size of the material to be cut and the positioning of the grommet. Typically, the dimensions for the material and the location for a grommet would be determined based on the design specifications of the life raft carrying case, which would be provided by the manufacturer or outlined in technical design documents. Given the reference to a 7 cm diameter PVC pipe for a different application, it is unclear how it pertains to the construction of the inspection data pocket unless the data pocket itself is designed to hold or interact with similar refills. Without exact design specifications, it is not possible to provide an accurate answer to this question.
The floating life raft should be capable of withstanding repeated jumps on it from a height of at least 4.5 metres above its floor, both with and without the canopy erected
It can be towed at 3 knots with its complete equipment, complement of persons and one anchor streaming.
Canopy to provide insulation and protection against heat and cold by two layers of material separated by an air gap
Interior to be of a non-discomforting colour
