A. When any mortgage of a ship under this Chapter shall have been fully paid or satisfied the mortgage may be cancelled in any manner provided by law for the cancellation of mortgages on immovable property. The effect of a mortgage of a ship shall cease if the inscription thereof has not been renewed in the same manner in which it was first made by the recorder of mortgages within one year after the date of the last installment provided for in such mortgage or within five years after the date of execution of the act of mortgage, whichever is later. Reinscription shall renew the effect of the mortgage for the amount unpaid for a period of two years from the date of the reinscription and further renewals may be made thereafter from time to time, the effect of each new reinscription being for two years from its date. The recorder of mortgages shall each receive one dollar for each cancellation and two dollars for each reinscription of a mortgage under this Chapter.
B. Recorders of mortgages may destroy the records of mortgages of ships in their respective offices two years after the date of the last installment provided for in such mortgage or six years after the date of execution of the act of mortgage, whichever is later, unless they have been reinscribed in the form and manner herein provided.
