long term immersion of the hull in warm water as
a primary cause of hull blisters. Stress cracks on
the hull below the waterline also contribute to the
formation of hull blisters.
Prevention
There are a variety of ways to prevent the formation
of hull blistering. Epoxy coatings can be applied
to the hull, followed by hull painting. An alkyd-
urethane-silicone marine paint can also be used to
aid in the prevention of hull blisters.
Reducing the amount of time that your boat stays
in the water also helps prevent hull blisters from
forming. Use of a trailer or boat lift will reduce the
likelihood of hull blisters forming. Be sure to use a
bunk type lift or trailer for storage of the boat out
of water.
Contact your Boston Whaler
information on the prevention and treatment of
hull blisters.

painting the bottom of your boat's hull is a good way
to slow the formation of hull blisters and to keep
bottom growth (fouling) under control.
If you will be trailering the boat to and from the water,
you might want to forgo the painting.
Following is an abbreviated section on painting the
hull bottom. Your Boston Whaler
information on properly painting your boat's hull or
recommendations on businesses that will paint your
hull for you.
CAUTION
!
DO NOT paint over zinc plates. This action will
render them useless and lead to deterioration
of the underwater metal parts of your boat.
Some bottom paints contain metals that can
cause corrosion of the outboard engine. Leave
a minimum of 3/4" unpainted around all engine
parts. Use only a paint specifically designed for
aluminum engines as anti fouling protection.
Bottom Painting a Bare Hull
WARNING
!
Proper ventilation and capture of the dust
created by sanding is essential. The dust
created by sanding is toxic and should not be
breathed. A proper fitting respirator must be
used.
DO NOT use a paper filter mask.
Preparation is the key to successful hull painting.
Take extra care and time in preparation before
proceeding to paint.
Begin by scrubbing the surface thoroughly with a stiff
brush using an all-purpose marine soap and water
to remove loose dirt and contamination. Flush with
fresh water to remove all soap residue.
The gelcoat will have to be dewaxed of mold release
wax before sanding can begin, otherwise the wax
will be dragged into the scratches and will reduce
the adhesion properties of the paint.
