The ship would not be in class, which would mean that she is not seaworthy in the view of courts, insurers, and the flag State Administration.
She would consequently lose her hull and machinery insurance and P&I cover, and have her statutory certificates withdrawn by the MCA, and the owner would lose his legal defences to claims. The cargo owner’s insurance would also be void if it contained a warranty that the cargo will be carried only on a classed vessel.
