Twistlocks, Container Twistlocks, Manual Twistlocks, Semi Automatic Twistlocks, Fully Automatic Twistlocks, Dovetail Twistlocks and Breech Base Twistlocks are all used on container ships to securing ocean cargo containers above deck only.  Below deck, under the hatch covers, stackers or hanging stackers are used.

Between the containers in a stack, you can use manual twistlocks, semi automatic twistlocks or fully automatic twistlocks.  "In the stack" means that both above and below the twistlock will be a container.

The bottom of the container stack is different.  This is the twistlock that goes between the container foundation and the 1st tier container.  Depending on the ship or barge you might find: manual, semi automatic or fully automatic twistlocks or you might find dovetail twistlocks or breech base twistlocks (ro-ro ships) or bottom versions of the standard twistlocks that have larger flanges for the higher compression loads you find at the bottom of the stack. 

In most countries you will no longer find manual twistlocks being used in the container stack as there is risk of falling for the person that is installing or removing them during container operations.  Manual twistlocks or bottom manual twistlocks will still be found on the bottom of the stack as well as on shore, on railroads container trains and in barge use.
