Lifejacket. Tying a double bow.

[cockney steve]

Perhaps a reef knot might fit the bill.

But, Shirly, a bow is just a reefknot where the second overhand has the free end doubled over?

then, to convert to a double, the 2 loops are then crossed in another overhand hitch.- the double has to have the last hitch unpucked before a tug on any free end "should" release the bow.....but if the knotsmith ties a "granny," all bets are off. webbing and plastic "plug n' socket clips are the 21 st. century way.

Thanks P.M.

The correct method of donning the lifejacket shall be reasonably self-evident to untrained passengers. The lifejacket shall be made to fit securely throughout its range of adjustment in all likely conditions of use and size of wearer. So far as possible, any adjustment necessary to make the lifejacket fit securely shall be made automatically when being donned. The wearer shall be able to make any re-adjustment without undue risk of the lifejacket slipping off. The lifejacket should be capable of being removed from the valise or container and donned by an adult passenger, seated in an aircraft, within 15 seconds unassisted, with a safety belt fastened.

Blimey. Hard to see the 2nd half of those statements being carried out with 'tape' type jackets. Worth me having a go next week during turn-round.
