No, any adult male at 230lbs will still be under the limit with 2 beers per hour. Not sure but most States do not have the law you refer to. .08 is the limit in most States. In Maine if you are found intoxicated operating your boat it is a $600 fine and the possibility of jail time, depending on how far over the limit. It does not go against your drivers license.
EDIT, EDIT, EDIT...... Ok, Yes, I see why my numbers and yours are different, I drink lite beer so was referring to lite beer (Coors lite or Miller Lite). I did not realize there was that much of a difference between Lite beer and regular beer. I sure am glad I stick with Lite beer then!! So you are correct, many people do drink regular beer and it will put you way over the limit.
230lb male 16 beers in 8 hours is .062 here is the link

If you are going to boat and drink, do it responsibly and stay within the law!
I am not saying to boat intoxicated, just stating that many times I will have a beer in my hand and be within the law. I hate readings about these tragedies that could have been avoided.
