GENERAL INFORMATION Design category DUFOUR 41 Your is design category A. A category A boat is considered to have been designed for sailing in conditions with winds below 10 on the Beaufort scale and the associated wave heights. NOTE: While these kinds of conditions are generally encountered during long voyages, such as ocean crossings, they can also occur just off the coast in areas that are not protected from wind and waves for several hundreds of nautical miles.
Indicates a recap of safety practices or draws your attention to hazardous practices that may result in physical harm to persons or CAUTION damage to the boat, its components or the environment. ENGLISH 11-07-2023 9/95 DUFOUR 41...

Where 220 V or 110 V installations are concerned, only use electric appliances that are double- insulated or earthed. When installing such equipment, follow the fitting instructions carefully (cable cross-sections, protection mechanisms). To prevent maintenance issues, note in the manual any changes made to the electrical circuit. ENGLISH 11-07-2023 12/95 DUFOUR 41...
Connect the electrical appliances’ metal covers or housings to the boat's ground conductor (conductor may be green or green with yellow stripe). Make sure all electrical appliances are either double-insulated or earthed. CAUTION! When the boat is in dock, place the circuit breaker in the “OFF” position. ENGLISH 11-07-2023 13/95 DUFOUR 41...

If the boat has an inverter that converts direct current (D.C.) to alternating current (A.C.), to prevent any risk of death or injury due to electric shock, disconnect the shore AC supply line and the inverter’s DC supply before opening any electrical panel or working on electrical circuits. ENGLISH 11-07-2023 14/95 DUFOUR 41...
In the event of an observed or suspected LPG leak, take the following steps immediately: Shut-off the main supply valve(s). Extinguish any open flames or other ignition sources (heating appliances, cooking appliances, night lights, etc.). Do not turn on or off any electrical switches. If possible, evacuate the area. ENGLISH 11-07-2023 15/95 DUFOUR 41...
It is vital to carry out a routine test each time you board the boat, or once a week during a longer cruise. If the test reveals the device to be faulty, replace it with a device of an equivalent type. ENGLISH 11-07-2023 16/95 DUFOUR 41...
After draining the water heater, make sure that its resistance is fully submerged before switching it back on again. Seacocks Seacocks are of the ¼ turn type: - OPEN position: the handle is in line with the seacock body, - CLOSED position: the handle is perpendicular to the seacock body. ENGLISH 11-07-2023 17/95 DUFOUR 41...
Clean the tank once per sailing season using a biodegradable disinfectant. Leave the tank system empty when the boat is docked in temperatures below freezing. During wintering, use a food-grade, non-toxic antifreeze that is conform to local regulations. ENGLISH 11-07-2023 18/95 DUFOUR 41...
Any non-flammable materials kept in the engine bay must be securely stored in such a way that they cannot fall on the machinery, or block the entrance or exit of the engine bay. ENGLISH 11-07-2023 19/95 DUFOUR 41...
● Hang loose curtains near the cooker or any other open-flame appliance. ● Store flammable products in the engine bay. ● Modify any onboard installation (especially the electrical, fuel or gas systems) nor allow unqualified people to make such modifications. ENGLISH 11-07-2023 20/95 DUFOUR 41...
Where possible, the engine must be stopped when carrying out any maintenance operation or engine inspection. If this is not possible, special care must be taken when close to moving parts (propeller shafts, belts, etc.) so as to avoid risks of injury. ENGLISH 11-07-2023 21/95 DUFOUR 41...
● Smoke while filling the fuel tanks. ● Obstruct ventilation ports (vent, engine ventilation grille): make sure they are kept clear at all times. ● Modify the installation unless this is performed by a technician with the appropriate marine engineering qualifications. ENGLISH 11-07-2023 22/95 DUFOUR 41...
Emergency tiller. CAUTION! ● The Dufour 41 is delivered with an emergency tiller that must be readily accessible at all times; we recommend that you store it in a cockpit locker. ● It is designed solely for sailing at reduced speed in the event of a steering wheel failure.
Keep your attention focused when moving from one helm station to the other. CAUTION! Some very large foresails (genoa, code 0, spinnakers, etc.) may obstruct the view over long periods of time. Keep an active watch while they are in use. ENGLISH 11-07-2023 24/95 DUFOUR 41...
When moving around the boat while under sail, use the various handholds whenever possible, including the wheel’s handrails, the cockpit table, the roof’s side rails, shrouds, etc. DUFOUR 41 is fitted with a telescopic boarding ladder fixed to the aft gate. To use the ladder, lower the aft gate by releasing the lifting cable then unfold the ladder and swing it into position.
● Some products may also present risks to your safety and the safety of other people; this is why it is essential to read and strictly follow the use recommendations. ● All substances used on the boat must be clearly labelled and stored in a suitable area of the boat. ENGLISH 11-07-2023 26/95 DUFOUR 41...
The aft lifting point is located near the engine’s sail-drive.
