Cl. 17-56 reads:
The provisions of Chapter 16 apply with the changes prescribed in Cl. 17-57 to Cl. 17-61.
Loss of time for fishing vessels is covered on the basis of Chapter 16, subject to the changes that follow from Cl. 17-57 to Cl. 17-61. These special rules are intended to apply only to fishing vessels and not to smaller freight vessels that are also insured on the basis of Chapter 17, Sections 1 – 6. Such freight vessels can obtain loss of hire insurance on the basis of Chapter 16 subject to any changes that might be laid down in the individual insurance contract.
