Question 865 Deck General

The correct answer is B) twist-locks and lashing hooks. On a Ro-Ro (roll-on/roll-off) vessel, which carries both rolling and container cargoes, the deck sockets need to be able to accommodate both twist-locks and lashing hooks. Twist-locks are used to secure container cargoes, while lashing hooks are used to secure rolling cargoes such as vehicles. Having deck sockets that can accept both types of fittings allows for maximum flexibility in cargo arrangements and efficient use of the available deck space. The other options are incorrect because: A) Container locks and bridge fittings are not the appropriate fittings for a Ro-Ro vessel carrying both rolling and container cargoes. C) Bridge fittings and lashing hooks do not provide the necessary functionality for securing container cargoes. D) Twist-locks and container locks are redundant, as twist-locks are the appropriate fittings for securing container cargoes.
