accessory manual. The amount of chain and line will
depend on the anchor selected and holding ground. It
is common to have about 20 feet of chain and
enough line to allow a 7 to 1 scope in the waters
where the boat is anchored. A good rode line will
have a bit of stretch but not break. For this reason,
nylon is often selected. Marking the rode with
commercially available tags at appropriate intervals
will prove invaluable in determining how much line
has been let out.
The anchor locker is equipped with a pad eye for
attaching the "bitter end" of the rode. It is
designed to secure the rode but not to absorb the
shock load if an anchor is allowed to free wheel
down in the waters deeper than the rode.
B. Windlass (optional) Operation
(see Fig_6.8-1)
The windlass is equipped with switches to operate
from both the helm (see Fig_6.11-1 and Fig_6.8-4)
and the foredeck (see Fig_6.8-1 and Fig_6.8-5).
Always secure the anchor to the boat after it is
raised. Relying on the gypsy to hold it in place is poor
practice. Also, after lowering the anchor, lead the
rode to the forward cleat. Do not leave the load on
the windlass as the shaft is not designed for the
strain.
(Fig_6.8-4)
(Fig_6.8-5)
The windlass is sized to raise the anchor and
rode, not to pull the boat. When preparing to
depart an anchorage, motor the boat forward over
the anchor while using the windlass solely for
rode retrieval. Let the forward motion of the boat
break the anchor free, allowing the windlass to
retrieve the anchor.
When operating the windlass make sure that all
crew members are clear.
7.10 Exhaust and Cooling Systems
A. Engine Exhaust System
Hot exhaust gasses are a by product of operating
diesel combustion engines. Your Back Cove 30 uses
a wet exhaust system which cools and muffles the
exhaust gasses using spent cooling water. The sea
water used in the engine cooling system is mixed
with hot exhaust gasses at the exhaust mixing elbow
(see Fig_6.9-1) before flowing out of the exhaust port
(see Fig_6.9-3) via. a exhaust elbow and dual-stage
muffler
(Fig_6.9-1)
B. Cooling System
Heat from friction and burning fuel is absorbed by
water circulating through the engine's internal cooling
passages. The proper functioning of this system is
critical to engine operation.
The diesel engine is equipped with fresh water-
cooling. The engine's internal cooling passages
contain a coolant mixture of fresh water and
antifreeze, like automobile engines. Instead of using
a radiator that cools the coolant with air, the cooling
system in the Back Cove cools with sea or lake
water. The transfer of heat from the engine coolant to
the seawater is accomplished by circulating hot
