OATING AFETY ECTION Safe Operation Boating safety is your responsibility. You must fully understand the operating procedures and safety precau- tions in the Owner’s Information kit and this owner’s guide before you operate your new boat. Safe boating is no accident. Safety Safe operation includes, but is not limited to, the follow- ing.
ECTION OATING AFETY • Always keep accurate, updated charts of the area you are cruising. Back up charts if you use a chart plotter. • Before you leave the port or harbor, file a Float Plan with a family member, relative, friend, or other responsible person ashore.

ECTION OATING AFETY Fog is a result of either warm-surface or cold-surface conditions. You can judge the likelihood of fog formation by periodically measuring the air temperature and dew point temperature. If the difference between these two temperatures is small, fog is likely to develop. Remember the following guidelines: •...
OATING AFETY ECTION • Close portlights, exterior doors and hatches and secure them. Stow all loose gear below deck and tie down any gear on deck. • Reduce speed as the seas build. Make sure all persons onboard have put on their personal flota- tion devices.
Page 16
ECTION OATING AFETY Never: • Obstruct passage ways to exits and hatches. • Obstruct safety controls, such as fuel valves, gas valves and electrical system switches. • Obstruct portable fire extinguishers in lockers. • Leave the boat unattended when cooking or heat- ing appliances are in use.
Page 17
OATING AFETY ECTION Smoking, poor maintenance or carelessness when refueling can cause hazardous conditions. Always follow proper refueling procedures for your boat. Flooding If your boat is taking on water from a leak in the hull, turn on your bilge pumps. Assign someone to bail out the bilge and investigate the cause of the flooding.
Page 18
ECTION OATING AFETY • If the bow of the other craft penetrated your boat’s hull, prepare to plug the fracture once the boats are separated. • Shore up the hole inside your boat with a spare life jacket or bunk cushion. •...

OATING AFETY ECTION If a person falls overboard, hypothermia may be an immediate concern. Hypothermia occurs when a person’s body loses heat faster than the body can replace it. If not rescued, the person will become exhausted or likely drown. In general, the colder the water, the faster body heat is lost.

ECTION NTERNAL YSTEMS Grey Water System Certain areas of the United States and Europe have initiated antipollution regulations that require the installation of a grey water system on boats. With the optional grey water system, all sink and shower drain water, as well as condensation from the optional air conditioning system, drain into grey water waste tanks rather than flow directly overboard.
Boat and Yacht Council (ABYC) has developed specific standards on how propane tanks must be installed. Carver has installed this tank according to the ABYC standards. Do not relocate or reposition the tank. NOTE: The propane tank valve outlet fitting and the regulator system nut, by law, have left-hand threads.
Never use flame to check your propane stove system for leaks. The propane stove system is inspected and pressure checked as part of Carver’s quality assurance process. We do, however, suggest that you test the system for leaks regularly. Use the following system inspection process every time you remove and reinstall the pro- pane tank.

The solution forms bubbles where propane is leaking from the system. If you cannot find the leak, contact SeaWard Prod- ucts or your Carver Dealer. 3. Have a qualified person repair the propane system. Propane is heavier than air and if allowed to leak, could settle and accumulate.
Additionally, the entire fuel system passed Carver’s own pressure testing and inspection. Before your boat is delivered, your Carver Dealer also makes a full inspection of the fuel system. An entry on the Carver Pre-Delivery Service Record verifies the dealer's completion of this inspection.

Engine Room Your boat’s engine room is equipped with a ventilation Ventilation system consisting of intake ducts, exhaust ducts and bilge blowers.
If you are not sure which type of cooling system is installed on your boat, contact your Carver Dealer. Both open and closed cooling systems require seawater to function. Before each cruise, make sure the strainers located near the seacocks are free of sea weed and other debris.
ECTION ROPULSION After starting your engines, check the engine exhaust outlet. If water is not being ejected from the outlet, immediately shut down the engines. Determine why seawater is not being pumped through the system. Have the problem corrected before restarting the engines. If the engine temperature gauges register a higher than normal temperature reading, the cooling system may need to be repaired.

Instructions on how to navigate your boat are beyond the scope of this guide. Carver encourages you to read Chapman's Pilot- ing and Seamanship and obtain instruction regarding how to navigate your boat.
ECTION PERATING AND ANEUVERING Depth Sounder The optional depth sounder can help you avoid entering waters that are too shallow for your boat and can aid in navigation. Speed Log Keeping a speed log is essential when trying to deter- mine your position over time.

PERATING AND ANEUVERING ECTION Leaving a Pier or Mooring Getting underway from a pier is normally accomplished by taking in all lines except the bow spring. With a neutral rudder, power the boat forward using only the engine farthest from the pier. The boat will pivot around the bow spring line, moving the stern out and away from the pier.
Page 140
ECTION PERATING AND ANEUVERING Landing at a Pier To land at a pier, approach the pier at a right angle. If you desire a starboard side landing, place the rudders to port and reverse the port engine to check headway. Leave the starboard engine in forward gear to swing the boat parallel to the pier.

ECTION PERATING AND ANEUVERING Maneuvering The propellers on your boat rotate in opposite direc- tions. With only the port propeller rotating, your boat tracks forward and to starboard in forward gear and backward and to port in reverse gear.

However, towing a capsized boat or a boat with a damaged hull is not recommended. In these situations, lend aid to the occupants and call the proper authorities.
ECTION PERATING AND ANEUVERING Check for anchor drag. Immediately after anchoring, observe shoreline landmarks. After thirty minutes, observe the landmarks again. If the points of reference have changed, reset your anchor. When weighing (pulling in) your anchor, pull the line in until it is vertical.
