If it is neither practicable nor reasonable to place on a vessel the minimum number of sets of davits required by the rules, the Board of Supervising Inspectors, with the approval of the Secretary of Commerce, may authorize a smaller number of sets of davits to be fitted, provided always that this number shall never be less than the minimum number of open boats of the first class required by the rules.

If a large proportion of the persons on board are accommodated in boats whose length is greater than fifty feet, a further reduction in the number of sets of davits may be allowed exceptionally, if the Board of Supervising Inspectors, with the approval of the Secretary of Commerce, is satisfied that the arrangements are in all respects satisfactory.

In all cases in which a reduction in the minimum number of sets of davits or other equivalent appliances required by the rules is allowed, the owner of the vessel in question shall be required to prove, by a test made in the presence of an officer designated by the Supervising Inspector General, that all the boats can be efficiently launched in a minimum time.

The conditions of this test shall be as follows:
First. The vessel is to be upright and in smooth water.

Second. The time is the time required from the beginning of the removal of the boat covers, or any other operation necessary to prepare the boats for lowering, until the last boat or pontoon raft is afloat.

Third. The number of men employed in the whole operation must not exceed the total number of boat hands that will be carried on the vessel under normal service conditions.

Fourth. Each boat when being lowered must have on board at least two men and its full equipment as required by the rules.

The time allowed for putting all the boats into the water shall be fixed by the Board of Supervising Inspectors, with the approval of the Secretary of Commerce.
