The main difference in any country is mission. The "Navy" is a branch of the government in questioned who uses military built ships as weapons. The Merchant Marines or Merchant deal in Sealift or moving materials from one place to another. The Merchant Marine may also defend the Merchant ship he or she is on but the ship is not necessarily used by the military. Now in the US Navy we have MSC or Military Sealift Command. MSC moves materials around the world for the military but is more of a merchant Navy. Also the merchant navy may have military sailors stationed on them such as many of the US Navy's oilers.
you won't be an actual part of the military but you will serve in our merchant fleet. Perhaps if the US Navy is not for you then perhaps the Military Sealift Command may be to your liking where you would serve on military transport vessels(not combatants).The Merchant Navy is a non-combatant commercial fleet, which deals with transporting cargo and occasionally, passengers, by sea.
There are two ships with this name : a real transport ship and a fictional starship * USS Antares (AKR-294) is a Fast Sealift ship previously assigned to the Military Sealift Command, and currently with the Ready Reserve Force under MARAD, Marine Administration and no longer using the US Navy designation. * USS Antares, a fictional ship of the Star Trek universe, was destroyed by a mechanical failure in its propulsion system, exacerbated by Charles Evans.

It is not a military custom it's a military command, 'stand at ease' means to relax from the 'stand to attention' command.
