8.2.1.3 window maintenance
A dab of petroleum jelly on the threads of the toggles
( only) will prevent corrosion. Twice annually , scrub the
gaskets with clean water and an old tooth brush. When dry,
dust with talc powder to resist sticking to the window.
Clean the window with clean cold water or with cleaner and
polish. NEVER WIPE THE WINDOW WHEN DRY, DIRT OR SALT WILL
SCRATCH THE SURFACE.
CAUTION !! NEVER USE SPRAY LUBRICANT, WD-40 OR THE
LIKE, ON ANY INJECTION MOLDED PARTS IN YOUR YACHT, THE
CHLORINATED HYDROCARBONS CONTAINED THEREIN TO DISSOLVE
RUST MAY INDUCE STRESS WITH RESULTANT BREAKAGE.
8.2.2 Below the Waterline
With the exception of small craft that are removed from the
water after each use, all vessels require some form of
bottom protection to avoid the accumulation of bottom
growth. This usually needs to be done on a yearly basis.
Although fresh water areas do not generate as much fouling
as occurs in salt water, it nevertheless will cause growth
of moss, grass, and other flora that will significantly
affect the performance of the yacht.
8.2.2.1 bottom cleaning
Cleaning the accumulated growth from a boat bottom is far
easier when the growth is wet than after it has been
allowed to dry out. While5till wet , a power spray and
stiff brush will remove most bottom growth. Barnacles that
resist this action can be removed with a scraper.
NOTE: WHILE CLEANING THE BOTTOM, REACH INTO THRU-HULLS,
CENTERBOARD TRUNK, BETWEEN THE SKEG AND THE RUDDER TO
REMOVE ANY BARNACLES.
8.2.2.2 bottom preparation
Most bottom paints require removal of all loose material
from the bottom, and a thorough but light sanding of any
portions of the old paint that remains in good condition.
A proper sanding procedure will normally take off approxi-
mately the same amount of old paint as is intended to be
reapplied. This avoids excessive paint accumulation that
will eventually cause peeling and roughness on the bottom.
8.2.2.3 bottom painting
The actual formula of the bottom paint that should be
applied is, to a great extent, determined by the general
area in which the yacht is expected to operate (fresh or
salt water, temperate or tropical areas1 etc.) Local
advice from reputable yards is helpful. Application of
bottom paint should always conform to the manufacturer1s
instructions if maximum effect is to be achieved. Some
