This is made from mostly old pieces, most notably the Caribbean Clipper. I like to think this ship is a little grander in scale than her predecessor. She's a variation of the standard brig design with seven guns, including a rotating cannon on the forecastle, six sails, and featuring a white eagle figurehead. Her name comes from the halberd fastened to the bowsprit.
Note: I've updated it a year later with some minor aesthetic changes and put a crew of classic minifigures on it.

Very nice, I first though the idol represented a seagull, which would have been nice too but for a battle ship a more though bird will do :p, I like the caribbean clipper references, great job
Thank you. I always thought the Caribbean Clipper lacked something that all the pirate ships had. I hope this vessel stacks up well with those.
