Because you are Gregory Peck as Captain Ahab in the 1956 version of 
Moby Dick, and I too struggle with subs and impatience, lemme offer you a suggestion: use a type of ship that's already been subbed, and just give her a name in your RP, no unique sub necessary. Starships and Technology subs take the longest to get approved because everyone and their mother wants to sub their own ship and gear. I know a guy who creates Open Market ships all the time, just for fun. Most of his stuff can be found under his

 and

 accounts - just look where all his Factory stuff is listed. Off the top of my head, his 
Venture-class Star Galleon would be a good candidate for a pirate ship, although it depends on what you're looking for.
You can also shop around in the 
Marketplace to see what other people have listed. There are tons and tons of starship subs, plenty of variety, and it'll save you a lot of time and effort.
