[No. 77

If of any material other than cork, its volume and distribution
shall be such that the buoyancy and stability of the boat are not
less than that of a similar boat provided with buoyancy of cork.
A metal boat of this type shall be provided with internal and
external buoyancy to ensure that the buoyancy of the boat shall be
at least equal to that of a wooden boat.
The minimum freeboard of boats of this type shall be fixed in
relation to their length; and it shall be measured vertically to the
top of the solid hull at the side amidships, from the water-level, when
the boat is loaded.
The freeboard in fresh water shall not be less than the following
amounts :—

The freeboard of boats of intermediate lengths is to be found by
interpolation.
The collapsible sides must be watertight.

(b) Decked Boats with either Fixed or Collapsible Watertight Bulwarks.

(i) Decked Boats having a Well Deck.—The area of the well deck
of a boat of this type shall be at least 30 per cent. of the total deck
area. The height of the well deck above the water-line at all points
shall be at least equal to one-half per cent. of the length of the boat,
this height being increased to one-and-a-half per cent. of the length
of the boat at the ends of the well.
The freeboard of a boat of this type shall be such as to provide
for a reserve buoyancy of at least 35 per cent.

(ii) Decked Boats having a Flush Deck.—The minimum freeboard
of boats of this type is independent of their lengths and depends only
upon their depths. The depth of the boat is to be measured vertically
from the underside of the garboard strake to the top of the deck at
the side amidships and the freeboard is to be measured from the top
of the deck at the side amidships to the water-level when the boat
is loaded.
The freeboard in fresh water shall not be less than the following
amounts, which are applicable without correction to boats having a
mean sheer equal to three per cent. of their length :—

For intermediate depths the freeboard is obtained by interpolation.
If the sheer is less than the standard sheer defined above, the
minimum freeboard is obtained by adding to the figures in the table
one-seventh of the difference between the standard sheer and the
actual mean sheer measured at the stem and stern post; no deduction
is to be made from the freeboard on account of the sheer being
greater than the standard sheer or on account of the camber of the
deck.

(iii) All decked lifeboats shall be fitted with efficient means for
clearing the deck of water.

REGULATION XXVII.

Motor Boats.

A motor boat carried as part of the life-saving appliances of a
vessel, whether required by Regulation XXXVI (2) or not, shall
comply with the following conditions :—

(a) It shall comply with the requirements for a lifeboat of
Class I, and proper appliances shall be provided for putting it
into the water speedily.

(b) It shall be adequately provided with fuel, and kept so
as to be at all times ready for use.

(c) The motor and its accessories shall be suitably enclosed
to ensure operation under adverse weather conditions, and
provision shall be made for going astern.

(d) The speed shall be at least six knots when fully loaded
in smooth water.
