I'd beware of the BOATUS web site, it looks like they sent out a form letter and didn't actually
research the laws. For example they say of
New York:
"
Registration Grace Period (Days): 90 days"
And that's true. What they have totally missed, is that NYS requires registration only for vessels that are
in the navigable waters of NYS for more than 90 days in a row. If you cross the bay to NJ or the Sound to LI, your 90 days starts anew. If you haul the boat out of the
water to
paint the bottom, your 90 days starts anew.
That's in direct contrast to some states like
Florida, where the clock counts how many days you are in the state during one year. No restarts and IIRC hauling isn't counted either. (Could be one calendar year or simply 365 days, I don't
recall.)
So BOATUS...a good start, like the SC note of a maximum tax of $300. Although I didn't see any note there that annual personal property tax would also accrue. (Ah, Caesar. Any Caesar, every Caesar, they all get their due, one way or another.)
But someone at BOATUS needs to go on the web and do a little more research to fill in the blanks.
