(5) If efficient means are provided for temporarily closing the openings in the shelter-deck in heavy weather, the freeing ports required by para. 11 (e) need not be provided. If, however, efficient means for closing the openings are not provided, whether in vessels with one or with more than one opening in the shelter-deck, then freeing ports with shutters properly hung are to be fitted, having a minimum area as follows:

If the freeing port area is less than that stated above, an addition is to be made to the freeboard of per cent. of the vessel's moulded depth, provided, however, that in the case of vessels treated under para. 12, the freeboard is not to be increased beyond that due to deck erections of the same length and character, but with open wells, as determined by the different regulations contained in the load-line tables affecting poops, bridge houses, and forecastles.

(6) The deduction for summer to be intermediate between Tables A and C, in proportion to the effective length of erections finally allowed for freeboard purposes, and the freeboards assigned to these vessels must never be less than would be assigned for a complete awningdecked vessel of the same dimensions.

(7) For the purpose of the assignment of freeboards, a hatchway having strong iron or steel coamings, with hatch rest bars of the usual description, and also cleats for battening down bars securely riveted to the coamings, athwartship beams and fore and afters, substantial hatch covers and tarpaulins, shall be considered to have "permanent means of closing." And a deck erection having no openings in it, except so protected, shall be held to be "permanently enclosed."

A. Correction in inches for a change of roft. in the length. B. Deduction in inches for summer voyages.

The above reduction in freeboard for summer voyages from European and Mediterranean ports is to be made from April to September inclusive. In
other parts of the world the reduced freeboard should be used during the corresponding or recognised summer months. Double the above reduction to be
allowed for voyages in the fine season in the Indian Seas, between the limits of Suez and Singapore. An additional freeboard of zin, shall be required
for all vessels up to and including 330ft. in length when entering the North Atlantic, when sailing to, or from, the Mediterrancan or any British or
European port, and which may sail to, or from, or call at ports in British North America or Eastern ports in the United States, north of Cape Hatteras,
from October to March inclusive.
