Sailing and SPD ships
SPD scripted ships are available both in Second Life and Inworldz, but Inworldz has a much higher proportion of sailable seas. We use sailing ships for combat, exploration and trading. The Celyddon Navy uses Port Celyddon as its base for patroling the seas and hunting pirates and smugglers. A smuggler is of course any ship that refuses to pay excise duties and tax. Pirates are the curse of any honest sailor as they pick on poorly defended trading ships to plunder cargo.
Merchant ships travel from port to port with cargos to sell, when they embark on a voyage they announce their cargo and destination in group chat, this makes them a target for pirates who may chase them or lay in wait. If a pirate sinks a merchant ship before it reaches its destination they get the cargo and make a nice fat profit.
Merchant ships are expected to pay the navy ten percent of the value of their cargo as duty. Any navy ships in the area will try to protect them from pirates because duty is only paid after the merchant reaches its destination safely. On the other had if a merchant wants to take a gamble they announce that they are smugglers, if which case the the navy will either ignore them of sink them as a demonstration to others.
Further information on the Naval Action or Flotsam and Jetsam websites where they seem to have excellent forums. Would be pirates might like to look at The Pirate King for lots of great background info.*
Demonstration SPD ships can be tried out at various shipyards including The Loose Cannon on Inworldz.
