Introduction
About this manual
This is the owner’s manual for the C-8 Daycruiser. It has been written to help you enjoy operating
your boat safely. It contains details of the boat, such as the supplied or tted equipment, its
systems, and operating instructions. Please read the manual carefully and familiarize yourself with
the boat before use. Ensure that everyone who will operate the boat reads this manual before use.
Keep this manual in a safe place and hand it over to the new owner if you sell your boat. If the
manual is lost, a copy can be downloaded or ordered from Candela.
This owner’s manual is not a course on boating safety or seamanship. It is not a detailed
maintenance or troubleshooting manual. For support or service, please contact Candela.
Receiving the boat
When receiving the new boat, remove the plastic wrapping and inspect the boat for any damage
while the carrier service are still onsite. Report any damage to the carrier service and contact
Candela. If there is no damage, proceed as follows:
1. Connect the boat to shore power. See "Charging" (page 75).
2. Turn on the main switch. See "12V battery switch" (page 47).
Recycle the plastic wrapping according to local regulations.
About C-8
The C-8 is an electrical hydrofoil speedboat. The front and aft foil technology enables ying
(foiling) half a meter above the water surface in speeds above 17 knots. The reduction of water
friction, combined with no transmission losses from the electric pod motor, makes the boat highly
ecient in driving range.
It is easy to extend and retract the foils in the user interface when conditions like speed and depth
change.
Dierent types of sensors measure the position, speed, and acceleration of the boat, to ensure
that a stable ride is maintained at all speeds.

Steering
The C-8 has an electrical steer-by-wire system. There is no physical connection between the
steering wheel and the rudder. If the electrical steering system is disabled, only manual steering is
possible. Manual steering is done by rotating the rudder, by hand.
The aft foil system
The aft foil system contains components of the combined propulsion and steering system, such
as the pod motor and rudder.
The rudder connection box contains the electric connections and cables for controlling the pod
motor. Never pull or strain motor cables. This can damage motor functions.
The retraction motor generates power for retracting and extending the rudder. The dierent
retraction modes are set via the user interface on the touchscreen.
The steering motor and connecting steering wire transmits the movements of the steering wheel
to that of the rudder.
The pod runs very quietly, and idle running is silent. The driver must always know if the pod is on
or o. Check that the propeller LED by the throttle is turned o.
The front foil system
The front foil system is only extended during foiling mode, and fully retracted inside the foil garage
during other driving modes. An actuator motor on each foil strut controls the foil during ight.
The foil is equipped with two sacricial anodes, protecting the metal in the front foil system from
galvanic corrosion.
The front foil system is extended and retracted via the user interface, on the touchscreen .

12 13
Height sensors
The main function of the six height sensors is to provide input for foil control, measuring the
distance between the hull and the water. The height sensors must be kept clean in order to
function properly.
Sonar depth nder (optional)
The sonar depth nder indicates sea depth and cays, via the user interface. Depth is not
measured while foiling. The sonar depth nder must be kept clean in order to function properly.

interface. During pumping, a faint buzzing noise and splashing water is heard.
To make a visual check, do as follows:
1. In the cabin, unscrew the hatch to the front bilge pump.
2. Check for water in the bow. A small amount of water is normal.
3. If there is excess water, wait for the automatic bilge pump to pump out the water, or start the
pump manually from the user interface.
4. If the bilge pump functions, the water decreases and splashing water from the bilge pump
drain outlet is heard.
5. If the water remains in the bow, the boat might be taking in water, contact emergency services.
Checking for water in the stern
Check for water in the stern by waiting for the automatic bilge pump to run. To make a visual
check, do as follows:
1. Open the sunbed hatch and remove the stowage bag.
2. Check for water in the stern. A small amount of water is normal.
3. If there is excess water, wait for the automatic bilge pump to pump out the water, or start the
pump manually in the user interface.
4. If the automatic bilge pump is out of order, perform manual bilge pumping.
Emergency steering
If the electrical steering system is disabled, steering is done by rotating the rudder by hand. If the
pod motor is still functioning:
1. Remove the aft box lid to access the rudder.
2. Slowly steer to safe harbor by rotating the rudder.
Loss of propulsion
If both steering and pod motor are disabled:
1. Anchor the boat, if possible.

performance of the craft. Consider the following factors and recommendations before setting out
to sea:
• Breaking waves are a serious stability hazard.
• Check the bilge water level; keep it at a minimum.
• Stability is reduced by any weight added above the main deck.
• In rough weather, hatches, lids, lockers, and doorways should be closed to minimize the risk of
ooding.
• Stability may be reduced when towing, or by lifting heavy loads using a davit or boom.
• Ensure that any load is suitably distributed, properly stowed, and secured.
• Stability is signicantly reduced at speeds above displacement speed.
Environmental awareness
WARNING!
Risk of damage to the environment.
• Only organic waste may be jettisoned at sea.
• Marine plastic pollution is a serious wildlife and environmental hazard.
• Comply with speed restrictions to avoid coastal erosion.
CAUTION!
Risk of damage to the environment.
• Keep bilges clean to prevent the automatic bilge pumps from discharging illegal euent.
• Comply with local marine discharge laws. Violators can be subject to penalty.
Comply with local marine discharge laws. Violators can be subject to penalty. Several sections
of this manual provide information on how to protect the boat and its passengers from the
environment. This section gives information on how the environment can be protected from the
boat and its passengers.
The environment should be understood as including one's neighbors as well as the world of
plants and animals.
In many regions of the world, there are strictly-enforced regulations regarding environmental
protection. It is the responsibility of the operator to be aware of applicable regulations and to
ensure compliance with them. Bear in mind the international convention against marine pollution
(MARPOL).

34 35
Safety Safety
No black water discharge at sea
The discharge of euent into navigable waters is forbidden by law in many areas.
If such discharge causes:
• Discoloration of the water
• A lm or sheen upon the surface
• A sludge or emulsion beneath the surface
It is the responsibility of the boat driver to ensure that they comply with local marine discharge
laws. Violators can be subject to penalty.
The black water tank must not be discharged at sea. It must be pumped out onshore at a waste
station.
Retain household waste until onshore
Retain any household waste until it can be properly disposed of onshore.
Considerations regarding noise and wake
Consider the safety and comfort of other boats, people and wildlife around you. Never make
excessive noise. Comply with speed restrictions and adapt speed to sea conditions.

For information regarding the propulsion, steering and foil systems, see About C-8.
The system components are accessed through hatches on deck, or in the cabin. Only open
the service-access hatches when a visual check is needed, or when a qualied technician can
support in maintenance and service.
WARNING! Risk of personal injury. Never open the high-voltage battery hatch. If smoke or
smell indicates a re from this area, immediately evacuate the boat.

Draining system
The draining system ensures that any water that enters the boat from waves, splashes, or rain
will drain. A well-functioning draining system is essential to maintain the stability and buoyancy
of the boat. Excess water is pumped out with the bilge pumps. The bilge pump drain outlets are
through-hull ttings and should be kept clear from debris.
The deck angle and its gullies allow for natural overow. Water accumulated around the skylight is
drained through a built-in hose leading to the anchor box.
Excess water in the anchor box is drained through an outlet on the starboard side of the boat.

Bilge pumps
To detect and remove water, the C-8 has three bilge pump positions:
• 1 automatic aft bilge pump – drains the rear stern
• 1 aft manual bilge pump – drains the front stern
• 1 automatic front bilge pump – drains the bow

The two automatic bilge pumps run every other minute, pumping out the excess water from the
bow and rear stern. They generate a faint buzzing sound while active. If necessary, the two auto-
matic bilge pumps can be activated manually via the user interface.
The automatic bilge pumps are electrical and remain active when the key is turned o. They will
not function if the 12V battery switch is turned o, or if the boat suers from power loss.
The manual bilge pump is located under the sunbed hatch and is only used if excess water has
accumulated in the stern. This water is pumped out by hand.

WARNING! Risk of ooding. If water enters the boat due to damage, do not rely on the
bilge pump system. The bilge pump system is not designed for damage control.
NOTICE! When the 12V battery switch is o, the automatic bilge pumps will not work.
NOTICE ! Check the bilge pumps regularly and keep the bilge pump drain outlets clear
from debris.
Checking the automatic bilge pumps
To check the function of the automatic bilge pumps, wait for them to start, or start them manually:
1. In the Outputs settings in the user interface, start each of the automatic bilge pumps.
2. A faint buzzing sound and the sound of splashing water indicates that the bilge pumps are
functioning.
3. If necessary, perform a visual check:
a. Open the sunbed hatch and make sure there is no excess water in the stern.
b. In the cabin, unscrew the hatch to the front bilge pump and make sure there is no excess
water in the bow.
