prevent the container being bodily shifted out the lashings are continued to the top shoes. All lashing should be separate in the that a single lashing wire should not be passed over a few shoes and then lashed at the final point. Each lashing should have a turnbuckle or bottle screw incorporated and there should be at least 60% free thread in them after completion of lashing. The bottom lashing and the top lashing should not be counted together fore the purpose of assessing the total number of lashings taken for the container. The top lashings are for bodily rise and as such should be counted separately. As a rule, if the SWL of the lashing wire is 2T then to lash the top of a 20T container the number of lashings should be a minimum of 10 (all well positioned), similarly the bottom should have 10. The bottom lashings may be reduced depending upon the chocking of the container and the availability of the lashing point. Note that a single strong for lashing should not have more than 2 lashing wires the preferred would be 1, however it is often impossible to find so many – lashing points. This shows a container ship lashing; note that the container is loaded onto the ship shoe slots which are strengthened, the rod lashings are only for the top of the containers. Here the bottom shoes are not lashed since the ships sunken shoes and twist locks effectively chock and lash the bottom of the container.
