Somehow I missed the post where you stated I don't have a clue and that I lack comprehension skills.
I think you are describing yourself there, it's pretty obvious by all the jibberish you've been posting on this subject.
I have been in the boat building business in the past. never took a course but have been exposed to this stuff a lot and know geometry pretty well too.
Seems like you don't know much at all but assume a lot and like to state opinion as fact, and disrespect people who disagree with you.
I'm done!
look at the picture, do you see the 112.5 angle? if so then this is where the "abaft of beam angle starts, this is how you measure the angles defined in the cg rule.
the jibberish is yours, you stated that you did not know to register a boat with a motor in Tx. this is a total rookie mistake and dropped your credibility a bunch.
go read up on how the measurements are taken, angles figured and get back to us, till then you are dead wrong in your assumption.
let me help ya a little (jeesh, some of you guys need to back up and think of what your posting), this whole deal was only to point out that LEDS ARE LEGAL IF INSTALLED RIGHT, got it? mine are installed right and comply with all regs per the cg, minus the little stamp that is non existent on any after market light (find me one that is stamped cg approved on the housing).
from tpwd regs.
Lights Required
All vessels including motorboats, sailboats, canoes, kayaks, punts, rowboats, rubber rafts, or other vessels when not at dock must have and exhibit at least one bright light, lantern or flashlight visible all around the horizon from sunset to sunrise in all weather and during restricted visibility.
Navigation Lights
Power Driven Vessels Underway: Power driven vessels of less than 20 meters (65.6 ft.) but more than 12 meters (39.4 ft.) shall exhibit navigation lights as shown in Figure 1. Vessels of less than 12 meters in length, shall show the lights in either Figure 1 or Figure 2.
Manually Driven Vessels when Paddled, Poled, Oared or Windblown
A sailing vessel of less than 20 meters (65.6 ft.), while underway shall exhibit sidelights and a sternlight which may be combined in one lantern carried at or near the top of the mast where it can best be seen.
A sailing vessel of less than 7 meters (23 ft.) shall, if practicable, exhibit the sidelights and a sternlight, or shall exhibit at least one bright light, lantern or flashlight from sunset to sunrise when not at dock.
All other manually driven vessels may exhibit sidelights and a sternlight, or shall exhibit at least one bright light, lantern, or flashlight from sunset to sunrise when not at dock. In vessels of less than 12 meters (39.4 feet), white lights shall be visible at a distance of at least two (2) miles. Colored lights shall be visible at a distance of at least one (1) mile. "Visible" when applied to lights, means visible on dark nights with clear atmosphere.
Proper navigation lights for Power driven vessels of less than 20 meters (65.6 ft.) but more than 12 meters (39.4 ft.) Proper navigation lights for Vessels of less than 12 meters in length

(b) "Sidelights" means a green light on the starboard side and a red light on the port side each showing
an unbroken light over an arc of the horizon of 112.5 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on its respective side. In a vessel of less than 20 meters in length the sidelights may be combined in one lantern carried on the fore and aft centerline of the vessel [,
except that on a vessel of less than 12 meters in length the sidelights when combined in one lantern shall be placed as nearly as practicable to the fore and aft centerline of the vessel].an unbroken light over an arc of the horizon of 112.5 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on its respective side.
http://www.navcen.uscg.gov/?pageName=navRulesContentThe beam of a ship is its width at the widest point as measured at the ship's nominal waterline. The beam is a bearing projected at right-angles from the fore and aft line, outwards from the widest part of ship.
now look at this picture again. pay attn to the 112.5 and the lines making the pie cuts, look real hard.
dam near every bass boat on the water since 1980 has the widest point just ahead of the console/consoles, this is the beam measurement not some made up point anywhere on the boat. look at my hull, the widest point is just ahead of the console and this is my beam. 22.5* abaft of the beam means from just ahead of my console to the stern 22.5*.
