How can i register all my ships at once in a bounty board ?

As Agmen already mentioned, long as your ship name makes it clear that the pilot is the same one registered on the board, you're free to make as many ships as you want without having to register each and every one of them on the board. This is also a general rule, and all the boards work that way. You have to keep two things in mind though:

• Even though you do not need to register each of your ships on the board, all of them must have the appropriate set of reputation as your character's stance, else it'd be a violation of bounty rules and would fall under PvP abuse (i.e. All your ships must be above neutral to the employer you're claiming a bounty for, and hostile to the factions you hunt on that ship).
  
• You can't switch ships to "teleport" across Sirius and catch your target during a chase, as that falls under abusing game mechanisms (i.e. If you start hunting a ship in New London but he manages to get away and heads to Taus, you cant dock your ship in Leeds and log another one in Tau-23. In such cases you'll have to fly there with the same ship you've been flying when you first encountered the target.

Most hunters have multiple ships parked in different regions so they won't have to fly through Sirius when they decide to move to another region to hunt in, and long as each individual ship's reputation fits the area it's hunting in you're gonna be fine, so you won't have to fix your rep to Liberty factions - for example - on a ship you intend to keep in Omegas.
