It would appear SAM that there are many many more laws and regulations governing boating in the USA than there is in MANY other countries that also regulate their waterways. If you had bothered to actually look at the available government information (at least I have taken the time to actually read ALL the available information) you would have been well aware of it before you opened you mouth (to have somewhere to place your feet).
Below is just a very very minute extract from YOUR boating laws.

5. Reckless, negligent operation; influence of alcohol or drugs; U.S. Coast Guard. (a) No person shall use any vessel or manipulate water skis, an aquaplane, or a similar device in a reckless or negligent manner so as to endanger the life, limb, or property of any person.

(b) No person shall operate any vessel or manipulate water skis, an aquaplane, or a similar device while under the influence of an alcoholic beverage, any drug, or the combined influence of an alcoholic beverage and any drug. (c) No person shall operate any recreational vessel or manipulate any water skis, aquaplane, or similar device if the person has an alcohol concentration of 0.08 percent or more in his or her blood. (d) No person shall operate any vessel other than a recreational vessel if the person has an alcohol concentration of 0.04 percent or more in his or her blood. (e) No person shall operate any vessel, or manipulate water skis, an aquaplane, or a similar device who is addicted to the use of any drug. This subdivision does not apply to a person who is participating in a narcotic treatment program approved pursuant to Article 3 (commencing with Section 11875) of Chapter 1 of Part 3 of Division 10.5 of the Health and Safety Code. (f) No person shall operate any vessel or manipulate water skis, an aquaplane, or a similar device while under the influence of an alcoholic beverage, any drug, or under the combined influence of an alcoholic beverage and any drug, and while so operating, do any act forbidden by law, or neglect any duty imposed by law in the use of the vessel, water skis, aquaplane, or similar device, which act or neglect proximately causes bodily injury to any person other than himself or herself. (g) Notwithstanding any other provision of law, information, verbal or otherwise, which is obtained from a commissioned, warrant, or petty officer of the United States Coast Guard who directly observed the offense may be used as the sole basis for establishing the necessary reasonable cause for a peace officer of this state to make an arrest pursuant to the United States Constitution, the California Constitution, and Section 836 of the Penal Code for violations of subdivisions (b), (c), (d), and (e) of this section. (h) In any prosecution under subdivision (c), it is a rebuttable presumption that the person had 0.08 percent or more, by weight, of alcohol in his or her blood at the time of operation of a recreational vessel if the person had an alcohol concentration of 0.08 percent or more in his or her blood at the time of the performance of a chemical test within three hours after the operation. (i) In any prosecution under subdivision (d), it is a rebuttable presumption that the person had 0.04 percent or more, by weight, of alcohol in his or her blood at the time of operation of a vessel other than a recreational vessel if the person had an alcohol concentration of 0.04 percent or more in his or her blood at the time of the performance of a chemical test within three hours after the operation. (j) Upon the trial of any criminal action, or preliminary proceeding in a criminal action, arising out of acts alleged to have been committed by any person who was operating a vessel or manipulating water skis, an aquaplane, or a similar device while under the influence of an alcoholic beverage in violation of subdivision (b) or (f), the amount of alcohol in the person’s blood at the time of the test, as shown by a chemical test of that person’s blood, breath, or urine, shall give rise to the following presumptions affecting the burden of proof: (1) If there was at that time less than 0.05 percent, by weight, of alcohol in the person’s blood, it shall be presumed that the person was not under the influence of an alcoholic beverage at the time of the alleged offense. (2) If there was at that time 0.05 percent or more, but less than 0.08 percent, by weight, of alcohol in the person’s blood, that fact shall not give rise to any presumption that the person was or was not under the influence of an alcoholic beverage, but the fact may be considered with other competent evidence in determining whether the person was under the influence of an alcoholic beverage at the time of the alleged offense. (3) If there was at that time 0.08 percent or more, by weight, of alcohol in the person’s blood, it shall be presumed that the person was under the influence of an alcoholic beverage at the time of the alleged offense. (k) This section does not limit the introduction of any other competent evidence bearing upon the question whether the person ingested any alcoholic beverage or was under the influence of an alcoholic beverage at the time of the alleged offense.. 655.6.

(c) Section 655.1 applies to violations of this section. (d) A violation of this section is punishable by a fine not exceeding one hundred dollars ($100).
