That could be a serious mistake.

Your boat might then refuse to follow the established protocols for
meeting and passing situations with other vessels at sea.

There is no doubt that it would display improper and/or confusing
signals.

Naming your boat George W. Bush might inspire you to begin peering
through the portlights of your neighbors in the marina to make sure all
romantic encounters were
between one man and one woman, (missionary style only, of course) as
well as to monitor everybody's activities to make sure that nothing
"evil" could be afoot.

Most of your crew would jump ship at the conclusion of any leg of your
voyage, but there's no doubt that the uninformed dock walkers would be
impressed with the howitzer on your flybridge and some would think you
looked "nautical" in that admiral's cap with far too much "scrambled
egg" on the visor.

Lastly, you could expect your expenses to skyrocket out of control. A
routine visit to the Marine Supply Store would require yet another
30-year mortgage on your home. Sadly enough, despite spending at record
levels, you would discover that so much of your wealth was diverted to
the profits taken by your so-called "friends" at the chandlery that the
vessel George W. Bush would still lack some of the most basic
essentials for a safe and trouble free voyage.

There would be one advantage. When you pulled up to the fuel dock, you
could simply raid the office, shoot the attendant, and take as much as
you wanted. (Thereby making your financial future, if not your vessel,
more secure).
