The boat
deck contained emergency equipment and was the launching station
for the lifeboats.
The two lifeboats
carried 25 people each, enough space for the crew and guests.
Safety and auxiliary
equipment installed here include:
boarding ladder
2 grocery hoists (port and starboard)
spare propeller blades
emergency steering wheel
life preserver storage
fuel and water tanks
stack
engine room skylights
CO2 fire suppression system for the engine room
Situated above
the after cabins is the Mather's Boat Deck, the top aft end exterior
deck. Named the Boat Deck because of the location of the lifeboats,
this area wastes no space. Starting at the forward rail and heading
aft, there are many necessary items located on the Boat Deck. Ventilation
stacks are very numerous and have fans to ventilate the accommodations
below. The four large ones ventilate the engine room. The two small
skylights supply ventilation and illumination to the Crew's Hall Aft.
The mast rises
to the height of the stack. It carries the boarding ladder, its winch
and, on top, the required FAA clearance lights due to the Mather's
proximity to Burke Lakefront Airport. Also located on the mast,
are the load trim lights. These are used by the First
Mate when he loads the boat to balance the weight of the cargo in
the holds. The colors of the load trim lights have different meanings.
White light in the middle means the boat is trim. Red or green lights
indicate a list to port or
starboard, respectively. There are also trim lights on the forward
mast. Forward, the trim lights measure the ship's rolling in heavy weather.
Aft of the mast,
and to each side of the forward edge of the stack, one can see a large
plate welded into the deck. The plate's purpose was to cover the opening
of the original coal bunker. The stack with its large red "C"
is actually a shell to cover exhaust pipes, boiler equipment and storage.
The ship's whistles, or in our case steam horns, are protruding from
the forward surface of the stack. These horns are now operated on compressed
air. The whistles (horns) are communication devices between vessels.
Meeting, overtaking, fog, danger signals, fire and boat drills, etc.
are blown with these whistles.
Attached to the
stack is a house that extends around the after ½ of the stack.
In these spaces are the Emergency Generator room (stbd. side), lube
oil storage tank (aft) and the CO2 fire fighting equipment room (port
side). The emergency generator supplies limited lighting in case of
total power failure. Located high in the ship (in case of foundering),
it is a 45hp Nordberg diesel with a 30kw generator which is still operational.
The lube oil storage
tank holds the oil that supplies a constant flow of the lubricant to
the steam turbine propulsion engine, reduction gears and the generators.
The oil is pumped to the tank from the lower engine room. Gravity then
carries the oil back to the machinery. The oil is used, then cooled
and cleaned, and again pumped up to the tank.
The CO2 (Carbon
Dioxide) room contained the 72 75 pound bottles that stored the CO2.
The purpose of the bottles was battling large fires that could occur
in the engine room. If a fire could not be extinguished in the engine
room, all personnel would leave the space and the CO2 system would be
tripped. CO2 would displace the oxygen in the space and smother the
fire. The Mather's system was disabled and the CO2 bottles sold.
Presently, several CO2 bottles remain to illustrate the system.
Aft of the stack
and amidships, is the Engine Room skylight. It allows light and ventilation
of the engine room. Since skylights are a throwback to the days of poor
lighting and ventilation, modern vessels do not have them.
The two large
tanks on the boat deck contained diesel fuel (port) and fresh water
(stbd.). The fuel and water were necessary supplies for the winter shipkeeper.
The shipkeeper's function was to provide security and labor during the
winter lay-up period. Behind the diesel and water tanks, there was a
rack that contained the after life raft. The raft was probably six or
eight 55 gallon drums welded together with boards on top.
Outboard of these
tanks are the Mather's two lifeboats. The lifeboats could accommodate
the entire crew and the guests. Equipped with oars, a sea anchor, storm
oil, a compass, flares, flotation tanks, sail, a bailing bucket and
a small stash of survival gear, the boats evacuated the crew in case
of fire or foundering. To operate the lifeboat, crewmembers swung it
over the side using the davits. The function of the davits was to lift
and swing the lifeboats. Once the lifeboat was over the side, gravity
allowed it to be dropped to the water. Knowledge of the lifeboats was
absolutely necessary. Once a week, the crew participated in a lifeboat
drill to practice the launching of the lifeboats. When the seas are
rough, lifeboats are extremely difficult to launch. For this reason,
crewmembers sometimes allowed lifeboats to float free from a sinking
vessel. In modern times, inflatable life rafts and neoprene survival
sits compliment the still standard lifeboat.
Just forward of
the ship's flag pole, is the emergency steering station. Here the crew
could steer the ship using a compass, telephone (connected to the Pilot
House), and a large two-wheeled helm. The two-wheeled helm served
as a back-up in case the steering engine in the Engine
Room failed. The two-wheeled helm is a completely manual way to
turn the rudder.
Located behind
the lifeboats are the grocery hoists and the fueling hose hoist. When
the ship required supplies, they would be delivered either dockside
or by small boat. Supplies were brought on the ship by the grocery hoist
and its basket.
The most interesting
pieces of equipment on the boat deck are the 2 spare propeller blades.
The propeller blades weigh 3,200 pounds and are made of manganese bronze.
Most ships carry spare propeller blades because the original propeller
could suffer damage from the bottom of the lake, ice, logs, etc. A shipyard
installed the spare propeller blades. The slight damage done to the
Mather's spare propeller blades is an indication that they have
seen action.
