seagoing vessels.
(b) Nothing in these Rules shall interfere in the operation of special rules made by an appropriate authority for
roadsteads, harbors, rivers, lakes or inland waterways connected with the high seas and navigable by seagoing
vessels. Such special rules shall conform as closely as possible to these Rules.
(c) Nothing in these Rules shall interfere with the operation of any special rules made by the Government of any
State with respect to additional station or signal lights or shapes or whistle signals for ships of war and vessels
proceeding under convoy, or with respect to additional station or signal lights for fishing vessels fishing as a
fleet. These additional station or signal lights or whistle signals shall, so far as possible, be such that they cannot
be mistaken for any light, shape, or signal authorized elsewhere under these Rules.
(d) Traffic separation schemes may be adopted by the Organization for the purpose of these Rules.
(e) Whenever the Government concerned shall have determined that a vessel of special construction or purpose
cannot comply fully with the provisions of any of these Rules with respect to number, position, range or arc of
visibility of lights or shapes, as well as to the disposition and characteristics of sound-signaling appliances, such
vessel shall comply with such other provisions in regard to number, position, range or arc of visibility of lights or
shapes, as well as to the disposition and characteristics of sound-signaling appliances, as her Government shall
have determined to be the closest possible compliance with these Rules in respect to that vessel.

Question 12

What is a vessel constrained by draft?

Answer 12

The term “vessel constrained by her draft” means a power driven vessel which because of her draft in

Answer 20

Look-out
Every vessel shall at all times maintain a proper look-out by sight as well as by hearing as well as by all available
means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation
