Operating Manual for Sea Daze 4788 Bayliner
Sea Strainers: Ensure the valves on each RAW WATER THRU-HULL are open. (The lever is in-line with the
hose or valve). The Raw Water Thru-hulls are normally left in the open position. However, if they are closed,
there will not be any water flow from the stern exhausts when the engines are running. This will lead to a
serious overheat condition and engine damage. Look through the glass of each RAW WATER SEA
STRAINER for debris. A flashlight held behind the glass strainer makes it easier to see debris. A clogged
strainer will cause the engine to run hot or overheat. If necessary, close the thru-hull valve, open the strainer
cover, clean out debris and reassemble. Remember to reopen the thru-hull valve.
Exit the engine room, reposition the sound barrier and lock in place with the 4 cams.
From the Cockpit Lazarette check the following:
• Steering fluid level
• Trim Tab fluid level
• The Battery electrolyte level should be checked once a week. Verify the electrolyte covers the plates,
but remains below the fill tube.
Use distilled water only, or you will damage the batteries. Distilled water is stored in the port side lazarette, do not fill
with bottled water, or tap water it typically has small amounts of mineral, or other elements that will degrade the batteries.
Do not over fill the cells as this can prevent venting of the battery during charging and cause an explosion.
3.3.3 Shore Power Disconnection
If at a marina you will need to disconnect the shore power cable(s). Before disconnect verify the power switches
are turned off inside the power panel. For safety always disconnect starting at the dockside power pole to
prevent dropping a live line into the water. Turn off the pole (breaker or switch), unplug the power cable and
coil it neatly as you walk to the boat to avoid creating a trip hazard on the dock. Disconnect the cable from the
boat last, remove and store the adaptors in the container under the starboard Pilot House settee cushion with the
coiled shore power cable.
3.4 Electronics (Preparing for Navigation)
The Salish Sea is a marvel of nature with many safe passages, stunning bays, harbors and marinas; however it
also has many treacherous areas that require constant vigilance. The skipper has a tremendous responsibility for
the safety of their passengers and to other boaters. Before departure the skipper should fully familiarize
themselves with all navigation equipment and how it operates. Applicable charts should be reviewed each time
the boat is put under way to assure the intended course is appropriate for a large vessel such as Sea Daze and
that all hazards to safe navigation are known by the skipper and any person that will operate her.
3.4.1 Selecting a course and preparing the electronics for navigation
A word of caution, most skippers today rely on GPS and electronic charts with a perception that these highly
useful devices provide pin point accuracy. The reality is that the entire GPS system is far less accurate than you
may expect. For national security the civilian GPS signal is intentionally degraded and may be as far as 20
meters off. The date of publish on many NOAA and Canadian chart is deceptive. Many newer charts are based
on surveys taken in the early to mid 1900's and the equipment of that era was common to be inaccurate to 20
meters or even greater. The majority of today's recreational chart plotters (GPS) are digitized from NOAA and
other international paper charts. The digitization process is not precise and will introduce additional error. If
we take a 20 meter error in GPS, add a 20 meter error in the survey underlying the chart and consider the
inaccuracy of digitization we may have 40 meters or more of potential error; 40 meters is 132 ft and that is close
to 3 times the length of Sea Daze!
