Substitution of Vessel, Transhipment and Forwarding.
Wheter expressly arranged beforehand or otherwise, the Carrier shall be liberty to carry the goods to their port of destination by the said or other vessel or vessels either belonging to the Carrier or others, or by other means of transport, proceeding either directly or indirectly to such port and to carry the goods or part of them beyond their port of destination, and to tranship, land and store the goods either on shore or afloat and reship and forward the same Carrier’s expense but at Merchant’s risk. When the ultimate destination at which the Carries may have engaged to deliver the goods is other than vessel’s port of discharge, the Carrier acts as Forwarding Agent only. the responsability of the Carrier shall be limited to the part of the transport performed by him on vessels under his management and no claim will be acknowledged by the Carrier for damage or loss arising during any other part of the transport even though the freight for the whole transport has been collected by him.
（4）提单首要条款为海牙规则
（5）提单是全程提单，没有列明转船地，正面没有标明可转船
问题：
A．该格式条款是不是有意削弱或减轻了承运人在海牙规则下的责任？
B． 在德国法下是否有效?或者在英国法下是否有效？
C． 我方希望在租约中加入一条：carrier's liability cover the whole voyage from 装港 to 卸港. 但船东不接受。如果那条格式条款有效，我们加入什么条款或者改变什么条款能够更好的保障自己的权益呢？
