Engine Control Panel

Control panel is located inside next to the pilot house helm station

Engine Battery Switch

The engine battery is automatically isolated

Engine Hour Meter

Located in DC breaker cabinet in galley (just above the refrigerator)

Fuel Gauge

Stoic has two fuel tanks and two gauges

Location: The gauges are located aft of the DC switchboard

Top: Starboard | Bottom: Port

To operate: Power them by clicking the engine start switch one click clockwise


The engine may be started from the inside or outside helm station. See full engine starting procedure for details.


There is one throttle/shifting lever for each helm station.

  • Outside Binnacle: To throttle up in neutral: push button in at base of leaver, jiggle handle, and move forward or aft
  • Inside Helm Station: To throttle up in neutral: grip lever at the base and pull out, then move forward or aft


Center (straight up) is neutral, forward (forward), and reverse (backwards)


  • Stoic has two helms, one located outside on the binnacle and one inside the pilothouse.
  • To switch which helm is active use the lever at the starboard base of the binnacle. Mech = Outside helm | HYD = Inside helm
  • The inside helm turns many times to get the helm over one way or the other. It can be helpful to remove the cover of the autopilot control (left of the radar and Garmin) and view the rudder angle there.

Note: It is prohibited to steer from inside while docking, picking up a mooring ball, anchoring, or anything else that requires heightened awareness.

Engine Starting

  1. Put transmission in the neutral position (straight up on shifter lever)
  2. Turn on the engine control panel by clicking the ‘start’ switch at the interior engine panel one click clockwise. Note: This must be done on the inside engine switch, even if starting at the binnacle.
  3. Alarm lights will light up on the panel, Stoic does not have an audible engine alarm, it instead has a diamond shaped red alarm light at the inside helm station between the instruments.
  4. Hold the “start” switch clockwise for a few seconds until the engine turns over
  5. Let the engine warm up for 5 minutes in idle or with throttle no more than 1000 RPM. Note: The tachometer is with the other engine gauges at the engine panel, it is the most outboard gauge.
  6. Check transom for water and exhaust (turn engine off immediately if no water is pumping out through the exhaust)
  7. When the engine is warm, gauges should read as follows:
  1. Oil pressure ~29 psi
  2. Water temperature ~175 degrees
  3. Racor pressure: 1 “Hg

Engine Use

  • Stoic’s cruising RPM is 2100-2200 PRM
  • The boat should motor at around 6.5 knots and use .6 - .7 gallons per hour at this level
  • Stoic has a right handed prop and walks to port in reverse

Stop Engine

  1. Let the engine idle for 5 minutes before shutting down.
  2. Be sure both gear shifters are in neutral
  3. Turn off engine by: 
  • Outside binnacle: push and hold the engine control switch counter clockwise
  • Interior engine control panel: Push in and hold the “stop” button until the engine turns off
  1. Once the engine is off you can turn off the engine panel by moving the “start” switch one click counter clockwise (so it is vertical). Note: Do not switch the interior engine control panel switch vertical until the engine is off.


AC Electrical Switches

Located forward of the DC switch panel; labeled “shore power

House Battery Switch

Stoic does not have a traditional 3 way battery switch. There is a master DC breaker in a compartment under the interior helm station but this is normally left on.

Battery Charging

Charged by either shore power (make sure AC power and battery charger switch are turned ON) or by running the engine.

Note: The engine start battery is only charged by the engine alternator and will not charge from the AC battery charger.

Monitoring Batteries

Monitor levels when using DC services while the engine is not running.

Location: Battery voltmeter is on the wall aft of the salon table (Xantrax battery monitor)

To operate: Press the left button to switch between battery banks

Main = house bank | Aux = engine bank

DC Electrical Panel

Location: Switch Panel located at the interior helm station. Breaker panel located in a cabinet above the refrigerator.

Note: When leaving the boat, switches on the DC panel are turned off but the breakers are left on. Therefore, make sure the refrigerator, house lights, VHF, radar, and stereo are turned off at the device.  


Location: Below settee.

Control panel location: Aft of dinette. On/Off toggle on battery charger panel
Stoic is equipped with a DC to AC inverter, meaning some of the AC outlets can be powered by battery power. These outlets are labeled and are: Under the dinette, In the aft berth, and in a cabinet under the engine panel. Converting DC to AC uses a lot of power, it’s advisable to only use this feature when necessary and keep an eye on the state of the batteries as they will drain quick.



GPS/Chart Plotter

Location: at interior helm station

To Operate: Turn on “nav instrument” switch on the DC panel. Then push the “power button on Interior Garmin echomap DV. The Garmin echomap on the binnacle will only work if the interior one is powered.

Note: The Garmin Echomap is NOT powered by the ‘nav instrument’ switch so it must be manually powered down after use.

If the Garmin on the binnacle wont turn on it’s possible its connection came loose. To check this open the pod it's attached to with the allen key in the salon table drawer labeled ‘Instrument Pod’. Open the pod and reconnect the cable to the Garmin.

Navigation  Instruments

Location: in the cockpit

To Operate:

  • Turn on the ‘nav instrument’ switch on the DC panel
  • Turn on Garmin echomap DV at interior helm station, then the Garmin echomap on binnacle, chart data and real time depth soundings will only be displayed on the binnacle unit if the interior one is powered.
  • Speed, and wind will read automatically. Depth will only be found on the Garmin echomap unit. Do NOT change settings.

Note: The Garmin Echomap is NOT powered by the ‘nav instrument’ switch so it must be manually powered down after use.


Location: at interior helm station

To Operate:

  • Remove Raymarine cover (the panel it is mounted on is designed to be removed; remove the cover carefully.)
  • Press and hold the power button. Radar will take a minute to warm up.
  • Press the power button once and then hold clear to stop transmitting
  • Press and hold the power button to power down the unit

Note: The radar is NOT powered by the ‘nav instrument’ switch so it must be manually powered down after use. 



110% Genoa is on a rolling furler. Jib sheets lead back to the cockpit. 

  • Uncleat the furling line and unfurl slowly (especially on windy days)
  • Get 2-3 wraps around the genoa with the sheets when done and lock off sheets on cleats
  • Stoic has a baby stay forward of the mast. It is advisable to furl the genoa when tacking so it clears the stay easier.


Mainsail is stored in a stack pack with lazy jacks.

Raising the Sail

  1. Halyard is always attached. Do not detach halward from the mainsail. It should be led aft to the boom/stack pack to keep it from slapping on the mast in the wind. Unclip it so it can run free.
  2. The sail cover zipper can be unzipped from the aft end of the boom and zipped closed from the forward end of it using the thin white line with blue fleck. Make sure the forward end of the line is uncoiled and can run clean, then pull the line at the aft end of the boom to unzip the bag. The zipper can get stuck so be mindful and do not pull too hard if there is resistance. Once the bag is open, coil the line at the aft end of the boom and store it in the sail bag.
  3. When raising a sail, make sure the vang and mainsheet are not too tight.
  4. The halyard runs to a clutch and winch on the starboard side of the mast.
  5. As the sail goes up, be careful that it doesn’t get caught on the white and blue zipper line and that the battens don’t get caught in the lazy jacks.

Lowering/Storing the Sail

  1. Release the halyard and the sail will fall into the sail bag.
  2. Do your best to gently flake the sail once it is in the bag.
  3. Uncoil the zipper line at the aft end of the boom, and zip the zipper closed by hand a foot or two.
  4. Find the zipper line at the port side of the mast, gently pull it so the zipper closes the bag, again be mindful of it getting stuck. It helps to have someone standing on the pilot house to watch and aid the zipper.
  5. Use a boathook (stored in the cockpit locker) to grab the main halyard and run it aft and secure it to the clip on the boom/stack pack. Once it is secured close the clutch and tighten the line at the mast so it does not bang on the mast in the wind.

Make sure the water intake seacock is open. Seacock located under the galley floor for fwd head. Under berth for aft head.

Head Operation:

  1. Move selector switch to ‘In/wet’
  2. Pump 3-5 times to allow water into the bowl
  3. After use, move the selector switch to ‘out/dry’ and pump contents until the bowl is empty.
  4. Move the switch back to ‘in/wet’, pump again a few times to bring in water, then continue to pump to move water through the hose into the holding tank. ~7 times for the aft head. ~15 times for the fwd head as it has to run all the way to the holding tank in the cockpit locker.
  5. Switch to ‘out/dry’ and pump until there is only water in the bottom of the bowl.

Bilge Pump

Bilge Pump (Electric)

Location: 3-way switch on panel at the engine panel. Bilge pump pickup is fwd of the engine and aft of the battery box. There is a filter for the bilge pump. Pump and filter are port of the engine.

To Operate: Switch to and hold “MAN (manual)” for continuous or “auto” for use with a float switch. Always leave the switch on “auto” before leaving the boat. 

Bilge Pump (Manual)

Location: In the cockpit next to the helm on the port side (there is a manual pump to pump out the holding tank near the companionway)

To Operate:

  1. Remove handle from cockpit locker
  2. Remove cover and insert handle
  3. Move the handle up and down to allow the pump to prime. There will be air in the system so be aware you will pump for a while before water comes out. When the pump is primed, moving the handle will be harder, but keep pumping as water is moving  through and out the bilge exit thru hull. Pumping will become easier as water exits the boat.
  4. Replace cover when done

Boat Systems


Sleeps 6 (V-berth, aft cabin, and midship berth)


Location: Control knob is inside the refrigerator. Compressor is in the cabinet under the DC switch panel.

Usually setting: 3.5-4 on control knob
Note: There is no switch for the refrigerator on the switch panel. You must be sure to turn the refrigerator off at the control knob after your charter and be mindful of it while not on shore power, refrigerators draw a lot of power.  


  • Propane tank is located in the anchor locker. Always make sure the valve on the tank is closed when not in use.
  • Propane solenoid switch is above the refrigerator. Please turn off the switch when not in use.
  • The switch operates the solenoid which controls propane flow to the stove
  • Lighter is located in a drawer fwd of the stove
  • Stoic is equipped with a propane ‘sniffer’ behind the stove. This device will detect and an alarm will sound if unburnt propane gas is detected.  

Note: Stoics oven runs a little cooler than the Force 10s you may be used to

Galley Sink

Seacock located behind the sink under the settee. It is normally kept closed. Water pressure can be turned on at the DC switch panel – Labeled “FW pump”.

Head Sink

Seacock is located under the sink inside the cabinet

Hot Water Heater

Location: behind the aft part of the settee. Switch is located at the AC panel – Labeled “water heater”. This is normally left off.

Anchor & Windlass

Primary anchor:

  • 44 lb Bruce style anchor with 228’ of 5/16th chain & 165’ ¾” rode.
  • Markings: Yellow: 10 F. Red: 20F. Yellow: 30F.
  • There is a snubber to relieve stress on the windlass forward of the propane tank
  • A salt water washdown hose is located in the anchor locker. Turn on the SW Pump to use. The pump itself is located in the FWD head and draws water from the head inlet.
  • There is a handle forward of the propane tank to manually raise the anchor in the event that the electric windlass fails. This is placed in a hole on the port side of the windlass for manual operation. It can also be used to break the clutch handle if it can’t be loosened by hand.   

Electric Windlass: 

  • Switch for the windlass is on the DC switch panel labeled “anchor winch. 125 Amp fuse is located under the indoor helm station.
  • Windlass only runs in the ‘up’ direction; the chain must be freehanded down by loosening the clutch on the windlass (located on the starboard side). Tighten clutch to stop chain feeding out and to raise anchor. A handle is located forward of the propane tank to manipulate the clutch handle and keep hands clear.
  • Remote is located in the cabinet under the DC switch panel.
  • There is a foot pedal next to the windlass. This is a pneumatic switch and can inadvertently trip itself from air expansion in hot weather. Due to this we ask that you use the remote and not the foot pedal.

Diesel Heater

Location: Control unit in aft berth. Heater in aft part of cockpit locker.

To Operate:

  1. Before operating it is imperative you check that nothing (fenders, lines, etc) is touching the heater itself in the cockpit locker and that there is nothing (stern line, shore power cord, fenders) covering the exhaust port (located just aft of the “Nauticat 39” on the port stern.) Make sure at least two outlets in the cabin are open.
  2. On the control unit turn the switch to ‘1’ then turn the knob to the desired temperature.
  3. The knob should be switched to its lowest setting when the unit is ready to be turned off.
  4. Turn the switch to ‘0’ to turn the unit off. The blower motor will continue to run until the heater has cooled down.
