This is my schooner.
Notes:
*The sterncastle (yes, it is a word) overhangs the end of the hull piece by only four studs. The base is one brick thick.
*The heavy crew is needed to properly crew prize ships. For longer voyages, the crew is reduced to 24 (There are about 40 aboard in the pictures).
*About me: I am 23, and have over $3000 USD of Lego pirate items. I have thirty-six ships assembled right now, and use them to play Evil Stevie's Pirate game.
*I found the green hair on Bricklink. Green female hair appeared in 6713 "Grip 'n' Go Challenge" and 6617 "Tough Truck Rally."
*Not every ship needs to be built high over the hull pieces. With mine, every available surface of the hull pieces of this ship is covered with decking. It isn't "empty."
*Since the webpage was posted, the sterncastle has been modified to have an angled back (like the 6285). I also added a staysail. I will post pictures soon.
