Rule 23-Power-driven vessels underway
(a) A power-driven vessel underway shall exhibit:
(i) a Masthead light forward;
(ii) a second masthead light abaft of and higher than the forward one; except that a vessel of less than 50 meters in length shall not be obliged to exhibit such a light but may do so;
(iii) sidelights; and
(iv) a stern light
*note on side lights. Red is port side (left) and green is starboard side (right)
search underway!
Power-driven vessels less than 65.6 feet long must exhibit a green light on the starboard side and a red light on the port side, in addition to an all-around white light, when underway between sunset and sunrise. These lights help other vessels determine the direction the vessel is moving and avoid collisions at night.
Port and starboard steaming lights and stern light
A masthead light, side lights and a stern light are the lights that power driven vessels less than 65.6 feet long and underway between sunset and sunrise exhibit.
There is no difference between vector addition and algebraic addition. Algebraic Addition applies to vectors and scalars: [a ,A ] + [b, B] = [a+b, A + B]. Algebraic addition handles the scalars a and b the same as the Vectors A and B

the spelling
One says value and the other has addition on the end.
Power-driven vessels less than 65.6 feet long must exhibit a white masthead light and a white stern light between sunset and sunrise when underway. Additionally, they should also display red and green sidelights when the visibility is restricted.
