To the extent of vessel coverage, the correspondence Exs.B-18 to B-20 and in particular Ex.B-20, letter of D-1 insurance company, is dated 20th April 1979; 9 days thereafter the vessel sank. The plaintiff had not paid any premium as soon as they received Ex.B20 and the premium was actually paid by cheque of the plaintiffs under Ex.B-23 dated 26.5.1979. As mentioned above, the said payment is almost a month after the vessel sank on the date of payment of extra premium. The plaintiff knew that the vessel is no more and has already sunk on 29.4.1979. Even if D-1 insurance company has acted on the basis of the said payment by encashing the cheque on 28.5.1979, the vessel as such was not in existence on the date of payment of premium. The plaintiffs, therefore, knowing the aforesaid facts have not disclosed the said fact while paying the premium. The trial court was therefore right in concluding that the extra coverage of Rs.5.00 lakhs cannot be claimed by the plaintiffs. I have therefore no reason to take different view that the one taken by the trial court. Point No.2 is accordingly answered against the plaintiff.
