On engine control panel


Port side, in front of the engine panel; combines direction and speed.


  • To engage transmission, push the lever forward or reverse until it “clicks” into place. To increase speed, continue to move the lever forward or reverse, watching the tachometer to ensure speed isn’t too high.

  • To disengage transmission, push in black button and move the lever forward. Speed can be adjusted when the lever is moved forward or back; transmission is disengaged as long as the lever does not move into neutral.

Engine Starting

  1. Push in the black knob on throttle lever
  2. With button depressed, push the throttle lever forward about 1/3
  3. Insert key and turn to “on” position (alarm will sound)
  4. Push in the start button for about 5-10 seconds and the engine should start
  5. At this point the audible alarm should turn off. If not, Stop the engine!
  6. Check transom for water and exhaust (turn engine off immediately if no water is pumping out through the exhaust)

Stop Engine

In neutral, pull stop cable until engine stops. When the alarm sounds, turn the key to the “off” position.


AC Electrical Switches

Located on the right half of the electrical panel. Main breaker switch is on top.

Four AC outlets are located: in the STB aft cabin, above the ice box, starboard side of the v-berth and in the cabinet in the head.

House Battery Switch

Located under the chart table. Keep the selector on “1,” as the engine battery switch is separate. Main DC breaker is also under the chart table above the battery selector switch. Both engine and house battery switches are labeled.

Battery Charging

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

Monitoring Batteries

Monitor levels when using DC services while the engine is not running. Battery voltmeter is on the DC panel.

DC Electrical Panel

Located on the left half of the electrical panel, with the main breaker underneath the chart table above the battery selector switch.



Location: Above the companionway.

To Operate:  In main cabin, turn “Garmin” switch on the DC panel to “on”

Navigation Instruments

Location: Either side of the helm

To Operate

  1. In main cabin, turn “instruments” switch on the DC panel to “on”
  2. Depth, speed and wind will read automatically.  Do NOT change settings.



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


Mainsail in fully battened

  • Halyard runs along the port side to the cockpit clutch
  • Boom vang and cunningham adjustments run back to cockpit clutches
  • Outhaul is at the gooseneck fitting
  • Please raise the boom to its usual position after sailing. Please make sure the boom is not resting on the dodger.


Water Tanks (2)

Location: Tanks are located under each settee in the salon

Fill Cap: Port and starboard

Capacity: 65 gallons (32.5 each)

Fuel Tank

Location: Under aft berth

Fill Cap: Aft on the starboard side

Capacity: 21 gallons

Holding Tank

Location: Under v-berth, forward port side

Capacity: 22 gallons

Pump-out Deck Cap: Located on port midship; labeled “waste”.

**Never pump the tank overboard**



Nothing goes in the bowl that has not been consumed first. Do not flush toilet paper → put TP in trash.

Make sure the water intake seacock is open. Located under the v-berth, port side.

Head Operation:

  1. Move selector switch to wet bowl
  2. Pump 3-5 times to allow water into the bowl
  3. After use, move the selector switch to “dry bowl” and pump contents until the bowl is empty.
  4. Move the switch back to “wet bowl”, pump again a few times to bring in water, then change to “dry bowl”, pumping water through until the bowl is empty.

Bilge Pump

Bilge Pump (Electric)

Location: 3-way switch on panel underneath chart table

To Operate: Hold to “manual” for continuous or “auto” for intermittent with a float switch. Always leave the switch on “auto” before leaving the boat.

Bilge Pump (Manual)

Location: Socket located aft portside in the cockpit next to the start panel. Handle is stowed in the propane locker.

To Operate:

  1. Insert handle into socket
  2. Move the handle up and down to allow the pump to prime. 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.
  3. Remove handle and place back in propane locker

Boat Systems


Has an icebox; no electrical system. Icebox drain is under the galley sink. When finished - drain, wipe clean and leave the ice box lid open after use to air out.


Basic Operation:

  1. Open gate valve on propane tank
  2. Turn on the solenoid switch located on the DC panel labeled “gas valve”.
  3. Light the propane lighter holding next to the desired burner.
  4. Push the knob in and turn the gas control knob on the stove to light. Once lit, keep pushing the knob in for 15 seconds to activate the safety sensor.

Shut Down:

  1. Turn off the solenoid switch “gas valve” on the panel
  2. Once flame is extinguished, turn off knob(s) on stove
  3. Turn off the valve on the propane tank. Especially make sure this is closed at the end of the day.

Galley Sink

The Y-valve to both water tanks is located under the galley sink. Seacock located in a cabinet under the sink. To access the water first turn on the “water pressure” switch on the DC panel.

  • If you hear the water pump turning on and off or running incessantly, first make sure you didn’t leave the shower running! Otherwise, it could be due to a low tank allowing an air leak which fools the system into turning on. Try switching tanks. Then refill the low tank when you can.
  • Underway, it is best to alternate tanks to keep weight distribution equal on your trip.

Head Sink

Seacock located under the sink. Keep closed until the sink is in use.

Hot Water Heater

AC and engine heat exchange operated. 5.3 gallon capacity. Make sure the tank(s) have water before operating.

Anchor & Windlass

Primary Anchor: In the bow anchor locker – 33 lb plow-type anchor with 100’ of 5/16” chain and 200’ of 9/16” rope marked in 30 foot intervals from the chain.

Secondary Anchor: Inside starboard anchor well – Danforth with 15 feet of chain.

Windlass: Maxwell RC8-8 – Engine MUST be running while the windlass is in use.

The windlass breaker is located under the chart table. The windlass operates with remote or switch in forward cabin. Remote has a short range. To use, stand close to where the v-berth locker is (near the receiver).

To Operate:

  • To lower anchor, first turn all battery breakers on, then control the pace of the outgoing chain by running at 5 second intervals.
  • Once the anchor is set, secure a snubber line to remove strain from the windlass overnight.
  • To hoist anchor, first turn all battery breakers on. Next, start up the engine to reduce load on the batteries. Now flip on the breaker for the windlass under the chart table. Finally, operate the windlass from the foredeck with the wireless remote. Have a second person monitoring chain as it fills the anchor locker.
