S/V Nevermore Ship's System Descriptions
Editor's note: * This document is spun off Aleida's Sub-System list version 11June04. * Observe that -- because section numbers are coded into the section headings -- we have turned the show contents" feature off, since it prepends its own computed section numbers to make a very silly list.

3 BOAT SYSTEMS
3.1 standing and running rigging (including mast-partners)
- - - - * standing rigging (including mast-partners)
- - - - * running rigging
(do we want this header, since it's just a
nuisance to put sails in subheaders under
it (which we didn't do, you'll notice)
(Maybe if I could think of more things to
list under standing rigging, I'd like to
have separate "standing" and "running" headers?)
3.2 Ship's Machinery
3.2.1 engine and transmission
Misc observations:
- Engine instrument panel gauge readings (05Sep07):
- Water Temp

| Weight | 4-1/2 lb (2 kg) |
More information can be found in the Jabsco Water Puppy Technical Data Sheet
This pump is mounted on the port side of the stern lazarette. A white, corregated plastic ("Bilge-flex"), 3/4" I.D. hose leads from the bilge to the pump. A white, corregated plastic, 5/8" I.D. hose leads from the pump to a through-hull port on the starboard side near the stern. Note that this is the same port used by the manual bilge pump.
The bilge pump is wired directly from battery #1 to the 3-way switch on the nav station breaker panel. The up position manually turns on the pump. The down position puts the pump in automatic mode, in which a "float switch" will turn on the pump when water level in the bilge rises. A 15-amp fuse is inline with the positive lead from battery #1. The yellow rubber fuse holder for this fuse is strapped to the wiring harness that runs directly above battery #1.
The float switch (which doesn't actualy float) for the bilge pump is located behind the aft-most panel above the port bench in the cabin (just forward of the nav station). An orange hockey-puck-sized rubber cover surrounds a microswitch which is affixed to a rubber diaphram. A black plastic air tube runs from the diaphram to a plastic air bell in the bilge. Rising water in the bilge will increase air pressure in the tube and activate the switch.
As of 9/3/2007, the switch is not sensitive enough to be activated by 6 inches of water. Deeper water might activate the pump, but the required depth is unknown. A newer model float switch (Jabsco Hydro Air Bilge Switch) will be ordered.
3.2.3.2 Manual Bilge Pump
This pump is mounted on stern lazaret to starboard of steering position. Its handle is tied to boat in stern lazaret. A second handle is aboard. Gray corrugated plastic hose, approx 1", leads from bilge to pump.
TODO: define hose to thru-hull, and position of thru-hull.
TODO: define model number, capacity, etc., of pump.
3.2.4 head
3.2.5 ice box
3.2.6 stove
3.2.7 fresh water system
3.3 Ship's Electrical Subsystems
3.3.1 12-volt DC
The main circuit panel above the nav table is organized into groups
of controls including (from left to right):
1. meters for battery voltage and current being used by ship's systems
2. one "bilge/sump" switch controlling the automatic bilge pump
3. a horizontal row of ___ combination circuit-breaker/switches
4. a vertical row of ____ combination circuit-breaker/switches
5. a little control box of amazing portent (WHAT IS IT?)
NOTE: we suspect it isn't part of the 12-volt main control circuits
x. TODO: any other devices on the control panel
Subsections below delineate each one of these, but in the order
3, 2, 1, 4, 5, i.e., in the order one might have to use the controls
====== - - - - - * main switch/circuit-breaker sub-panel (horizontal switches)
Battery voltage to this sub-panel's switches is OFF unless battery power
is ON on one (or more) main rotary battery switch
No voltage is applied to the remainder of the switches unless
the left-most switch of this sub-panel (named "WHAT??") is on.
====== - - - - - * sump/bilge switch
Voltage is ALWAYS on to this switch, even when main rotary switches are OFF.
It is always connected to power from Battery #1, through an inline fuse
located near the battery. Removing the fuse removes voltage from
the main panel's bilge-pump circuits.
====== - - - - - * meters (Voltage, current)
Voltmeter quirk: it appears to read high by approx 1.4 or 1.5 volts.
The zero-point for the meter has been adjusted to read battery voltages
correctly (per Ted's VOM); therefore the zero-point will be off-scale.
Ammeter reads only the current being used by ship's systems, but not
any usage by the engine; it especially does not indicate battery
charging; the ammeter on the engine control panel does that.
====== - - - - - * auxiliary switch sub-panel (vertical) at Nav Station
QUESTION: does the horizontal sub-panel's "main" switch also
control power to this sub-panel; we assume so.
- - - - * Batteries
Batteries #1 and #2 (controlled by top main rotary switch) are
"mixed use" (starting and deep discharge) batteries of the same type;
they're located below nav station seat; #2 is fwd, #1 aft
Powermaster DC-27P, flooded, 750 MCA, 200 min reserve
Battery #3 (controlled by bottom main rotary switch) is
"heavy duty marine starting" battery located in engine compartment
Powermaster (unknown model), flooded, (unknown values)
The two rotary battery switches are
Guest 2300A, 360-amp, 600-amp momentary;
both have AFD (alternator field disconnect) but they aren't wired.
hence it is very important that at least ONE battery be
selected =ON= at all times that the engine is running.
QUESTION: is there an alternator protector (West Marine catalog term)
protecting the alternator when all batteries are "OFF" while running?
