Aft on the main deck in the stern was the cabin for Master Christopher Jones, measuring about ten by seven feet (3 m × 2.1 m).Forward of that was the steerage room, which housed a whipstaff (tiller extension) for sailing control; not a wheel, as in later ships.Far forward on the main deck, just aft of the bow, was the forecastle space where the ship's cook prepared meals for the crew; it may also have been where the ship's sailors slept.
The Mayflower also had on board a saker cannon of about 800 pounds (360 kg), and two base cannons that weighed about 200 pounds (90 kg) which shot a 3 to 5 ounce ball (85–140 g).
She carried at least ten pieces of ordnance on the port and starboard sides of her gun deck: seven cannons for long range purposes, and three smaller guns often fired from the stern at close quarters that were filled with musket balls.
This voyage has become an iconic story in some of the earliest annals of American history, with its story of death and of survival in the harsh New England winter environment.
The culmination of the voyage in the signing of the Mayflower Compact was an event which established a rudimentary form of democracy, with each member contributing to the welfare of the community.
Gun deck passengers most likely used a bucket as a chamber pot, affixed to the deck or bulkhead to keep it from being jostled at sea.
