CHAPTER 4
Implied warranties and the case for a separate regime for marine insurance
Implied warranties
4.1 The Marine Insurance Act 1906 provides for implied warranties in relation to seaworthiness and legality. Perhaps surprisingly, the Insurance Act 2015 did not abolish implied warranties: sections 10 and 11 of the Insurance Act 2015 confirm that the provisions of the Act applying to breaches of warranty (and in the case of s11 other provisions) apply to implied, as well as express, warranties.1 Accordingly under s10 of the Act, breaches of implied warranties also result in suspension of liability, rather than a full discharge from liability for the insurer. Because implied warranties have not been abolished by the Insurance Act, it is necessary to address them in some detail.Implied warranty of seaworthiness
4.2 S39(1) of the Marine Insurance Act2 provides that in a voyage policy ‘there is an implied warranty that at the commencement of the voyage the ship shall be seaworthy for the purpose of the particular adventure insured.’ S39(3) provides that where a voyage will be conducted in stages, with differing requirements for each stage, there is an implied warranty of seaworthiness for each stage.3 Soyer argues that the reason the warranty of seaworthiness is implied in voyage policies is because the assured is usually in control/possession of the vessel before she embarks on a voyage and, in this respect, is capable of rendering her seaworthy.4 4.3 Note that the implied seaworthy warranty applies only at the commencement of the risk and the start of each stage of the voyage: s39(1) and (3).5 Seaworthiness is defined by s39(4): ‘A ship is deemed to be seaworthy when she is reasonably fit in all respects to encounter the ordinary perils of the seas of the adventure insured.’6 The definition of seaworthiness in Black’s Law Dictionary is ‘an ability to withstand ordinary stress of wind,Page 26

In a voyage policy on goods or other moveables there is an implied warranty that at the commencement of the voyage the ship is not only seaworthy as a ship, but also that she is reasonably fit to carry the goods or other moveables to the destination contemplated by the policy.
