Yo Yo gear

This is a type of rigging which enables lifting of weights in excess of the safe working load of the derricks. As given in the figure the heads of two derricks are placed close to one another and their whips shacked to each other via a strop which passes through a traveling block.In the figure, the total stress of 7 tons is equally shared by the derricks. As the SWL of the falls  aren't sufficient, gun tackles have been rigged as lifting purchases.

The traveling block is advantageous as in the absence of such an arrangement the whole load would come on one derrick alone in case one winch fails.

Arrangements to upright an upturned open lifeboat

How to upright an open lifeboat and the provisions available in a non-self righting lifeboat in events of upturning is a popular oral question.We already know that the righting strap provided in a life raft in order to achieve such a result.

Merchant shipping notices by Maritime and coastguard agency quotes:-

A life line bucketed round the outside of the lifeboat meant to enable persons to cling to the lifeboat if upturned in the form of bilge keels or keel rails together with grab lines secured from gunwale to gunwale under the keel.

 
Keel rails are steel grab rod fitted on the bottom of a lifeboat to provide a hand hold.These along with grab lines leading throughout the underside of the boat constitute the arrangements specially made in open lifeboats which do not have self righting capabilities.
