Mayflower structure and layout
The Pilgrim ship Mayflower was
beak-bowed with high, castle-like structures
aft that served to protect the ship's crew and the main deck from the elements—designs that were typical with English merchant ships of the early 17th century. Her stern carried a 30-foot high, square aft-castle which made the ship extremely difficult to sail against the wind and unable to sail well against the North Atlantic's prevailing
westerlies, especially in the fall and winter of 1620, and the voyage from England to America took more than two months as a result. The Mayflower's return trip to London in April–May 1621 took less than half that time, with the same strong winds now blowing in the direction of the voyage.
No dimensions of her hull can be stated exactly, since this was many years before such measurements were standardized. She probably measured about 100 feet (30 m) in length from the forward end at the beak of her prow to the tip of her stern superstructure aft. She was about 25 feet (7.6 m) at her widest point, with the bottom of her keel about 12 feet (3.6 m) below the waterline.
William Bradford estimated that Mayflower had a cargo capacity of 180 tons. Surviving records from that time indicate that she could certainly accommodate 180 casks of wine in her cargo hold. The casks were great barrels holding hundreds of gallons of
claret wine each.
This was a ship that traditionally was heavily armed while on trading routes around Europe, due to the possibility of encountering
privateers of all types. And with its armament, the ship and crew could easily be conscripted by the English monarch at any time in case of conflict with other nations. By 1620, the Mayflower was aging, nearing the end of the usual 15-year working life of an English merchant ship in that era.
The general layout of the ship was as follows:
masts: mizzen (aft), main (midship), and fore, and also a
spritsail in the bow area.
- Three primary levels: main deck, gun deck, and cargo hold.
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
tiller extension) for sailing control; not a wheel, as in later ships. Also here was the ship's
compass and probably also berths for the ship's officers. Forward of the steerage room was the
capstan, a vertical axle used to pull in ropes or cables. 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.
poop deck was above the cabin of Master Jones, on the ship's highest level above the stern on the aft castle. The poop house was on this deck, which may have been for passengers' use either for sleeping or cargo. On normal merchant ships, this space was probably a chart room or a cabin for the master's mates.
The gun deck was where the passengers resided during the voyage, in a space measuring about 50 by 25 feet (15.2 m × 7.6 m) with a five-foot (1.5 m) overhead (ceiling). But it was also a dangerous place in conflict, as it had port and starboard
gun ports from which
cannon could be run out to fire on the enemy. The gun room was in the stern area of the gun deck, to which passengers had no access due to it being the storage space for powder and ammunition for the ship's cannons and any other weapons belonging to the ship. The
gun room might also house a pair of
stern chasers, small cannons used to fire out the stern of the ship. Forward on the gun deck in the bow area was a windlass, equipment similar in function to the capstan in steerage, which was used to raise and lower the ship's main
anchor. There were no stairs for the passengers on the gun deck to go up through the gratings to the main deck. To get up to the main deck, passengers were required to climb a wooden or rope ladder.
There was no facility for a latrine or privy on the Mayflower, and ship's crew had to fend for themselves in that regard. 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.
Gun deck armament
The largest gun was a
minion cannon which was brass, weighed about 1,200 pounds (545 kg), and could shoot a 3.5 pound (1.6 kg)
cannonball almost a mile (1,600 m). 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. Later at New Plymouth, Mayflower Master Jones unloaded four of the pieces to help fortify the colony against invaders, and would not have done so unless he was comfortable with the armament that he still had on board.
Below the gun deck was the cargo hold where the passengers kept most of their food stores and other supplies. Other items included most of their clothing and bedding. The hold also stored the passengers' personal weapons and military equipment – armor, muskets, gunpowder, and shot, as well as swords and bandoliers. It also stored all the tools that the Pilgrims would need, as well as all the equipment and utensils needed to prepare meals in the New World. It is also known that some Pilgrims loaded trade goods on board, including
William Mullins, and possibly others; these also most likely were stored in the cargo hold.
