Existing vessels.

(a) In assigning load lines to an existing vessel the provisions of the regulations in this part shall be complied
with in principle and detail insofar as
is reasonable and practicable, having
regard to the proven efficacy of existing arrangements for a special service
voyage, and having particular regard
to the provision of sufficient means for
the protection and safety of the crew.
(b) Where it is neither reasonable nor
practicable to comply with this part in
its entirety, the assigning authority
will, in each case, report to the Commandant, U.S. Coast Guard, the specific matters in which the vessel is deficient with such recommendations as
may seem desirable. Upon the receipt
of this report the Commandant, U.S.
Coast Guard, shall determine such addition to the freeboard as will, in the
judgment of the Commandant, U.S.

Coast Guard, Dept. of Homeland Security

(2) The requirements in §§ 42.09–1 and
42.09–10 that relate to the assignment
of freeboards and to stability are applicable to each vessel subject to the requirements in this part.
(3) The assigning authority that assigns a vessel subject to the requirements in this part a freeboard under
part 45 of this chapter shall do so in accordance with the requirements in effect as of October 1, 1972.
(b) Steam colliers. Steam colliers that
have constructional features similar to
those of a tanker which afford extra invulnerability against the sea may be
assigned a reduction of freeboard from
that determined under part 42 of this
subchapter. The amount of such reduction shall be determined by the assigning authority, in relation to the
freeboard assigned to tankers, having
regard to the degree of compliance
with the supplementary conditions of
assignment laid down for these ships,
but without regard to the degree of
subdivision provided. The freeboard assigned to such a vessel shall in no case
be less than would be assigned the vessel as a tanker, as determined under
part 42 of this subchapter.
(c) Towed cargo barges with cargo
under deck. The freeboard is to be computed under §§ 45.15–1 to 45.15–97 of this
subchapter. The fresh water and seasonal markings where applicable are to
be determined under part 42 of this subchapter.
(d) Towed cargo barges with cargo only
on deck. The freeboard for barges of
this type is to be computed in accordance with the requirements of §§ 45.20–1
to 45.20–70 of this subchapter. The fresh
water and seasonal markings where applicable are to be the same as determined under part 42 of this subchapter.
(e) Towed cargo barges of the open
type. The load line shall be placed
where, in the judgment of the assigning
authority, the draft will be such that
no unusual hazard will be experienced.
In general, drafts assigned will be such
that the barge will remain afloat with
a reasonable freeboard after flooding of
the net available open space.

§ 44.05–20 Conditions of assignment.
(a) Steam colliers. The conditions of
assignment for steam colliers shall be
in accordance with the requirements of
part 42 of this subchapter, except that
in the case of steam colliers constructed with bulwarks, the freeing
port may be of a practically continuous
slot type, located as low as possible,
the clear area of the slot to be not less
than 20 percent of the superficial area
of the unpierced bulwarks. If, due to
sheer, or other conditions, the assigning authority considers that extra
local provision should be made for freeing decks of water, the slots are to be
located so as to have maximum efficacy.
(b) Towed barges. The conditions of
assignment for towed cargo barges
where the cargo is carried under deck
shall be in accordance with §§ 45.10–5 to
45.10–100 of this subchapter. In the case
of tank barges and cargo barges carrying cargo only on deck, compliance
will also be required with the supplementary conditions of §§ 45.20–1 to
45.20–70 of this subchapter. In the case
of cargo barges of the open type, assignment will be limited to barges in
unmanned operation and the construction of the vessel must be such as to
satisfy the assigning authority that no
unusual hazards will be experienced.
(c) Self-propelled barges. The conditions of assignment for self-propelled
cargo barges carrying cargo under
decks shall be in accordance with the
provisions of §§ 45.10–5 to 45.10–100 of
this subchapter. In the case of self-propelled tank barges and self-propelled
cargo barges carrying cargo only on
deck, compliance will also be required
with the supplementary conditions of
