I have created a blueprint for a potential 4 masted, 5 cannon per side, 4 decked frigate. The ship would support 6-8 players and be 2.5 times larger than the current Galleon. The ship would support 2 rowboats and have a 1080 degree wheel turn radius both left and right. I'll provide more specific details below, but let me know what you think about the design.
The capstan would have a top deck set of 4 pegs and a lower deck set of 4 pegs lined up and turning simultaneously.
The bowsprit at the front of the ship would have a sail attached making it the 4th sail.
The staircase to the lower decks would be made up of 2 staircases starting at the back intersecting and then redirecting towards the center of the ship with lower deck stairs being the standard stairs like the galleon has.
The 2nd mast (the one with the crows nest) would be positioned in front of these stairs and behind the "captains cabin".
The cabin would have a door on the side opposite the 2nd mast. The cabin would contain the cosmetics chests, armory and ammo, map table, and quest table.
In front of the cabin would be a 3rd mast and behind that mast is where the upper portion of the capstan would be.
Behind the capstan would be a set of small stairs on opposite ends of the bowsprit which hangs out over the ship's front end.
2 cannons would be positioned on top deck with full adjustment capacity and extensive range due to the height of the ship. The deck below that would have 3 cannons all sat behind hatches that would close automatically and become inoperable should the deck fill with water. The 2nd level cannons cannot be aimed as well as normal cannons due to limited panning and pitching nor can they fire pirates out.
Once the water in the ship reaches the intersection of the two staircases leading to top deck the ship would scuttle.
At the back of the ship 2 curved staircases would wrap around the 1st mast and the wheel for the ship would be on top of the staircase.
The rowboats would attach at the base of the curved staircases to the side of the ship instead of the back of the ship.
There would be 2 sets of ladders on each side of the ship both aligned in between the to top cannons and the center lower deck cannon.
The kitchen would be at the back of the ship under the curved staircases with a door placed behind the 1st mast. This room would have doors leading outside to a wrap around balcony meant for fishing and a way to access the rowboats.
A "crew quarters" would be under the kitchen behind the stair cases that converge into a single staircase. the room's appearance would be multiple bunked beds built into the frame of the ship and things that seem sea of thieves pirate like scattered about on barrels and tables.
The cannonball barrels would be positioned at the base of the stairs leading to the lower deck and at the front of the ship where the next set of stairs would be leading to the 3rd level. Both sets would be next to a support column in sets of 2 with one on each side of the beam.
Below the cabin on the 2nd level where the cannons are would be another set of stairs leading down to the 3rd level. This set of stairs is the same set that would be between the support columns and next to the cannonball barrels.
The 3rd and 4th levels would look similar to the 2nd level without cannons and instead contain non-interactive barrels. The 3rd level would contain 2 wooden planks barrels positioned near the middle of the ship at the base of the stairs leading to the 2nd level. The 3rd level would also have a jail near the front of the ship behind the stairs
The 4th level would contain a bunch of non-interactive barrels, a staircase at the back of the ship leading to the 3rd level, and lanterns. Very boring part of the ship, but could be used to store treasure. Imagine the 3rd level to the galleon without the jail.
will add the blueprint when I have time to recreate it in a digital format.
edit
here are some sprite blueprints. The colors are meant to represent objects and such. bright green is the floor that you walk on. The orange to brown transition is stairs. Refer to the notes above to determine objects.
