EXPERT ON BOARD
TYPES OF ANTIFOULING
A significant annual purchase,
which antifoul is best is a hotly
debated topic. In truth, the best
product varies a lot depending
on the boat, what you use it for
and where you keep it. There
are three main types...
1
ERODING
As the name suggests, eroding
antifoul removes itself with
friction, revealing a layer below that
continues to protect and actively
reject growth. Biocides protect
the hull whilst reducing the long-
term buildup of product that
can otherwise wear unevenly.
2
HARD FILM
If you’re on a drying mooring,
you’re more likely to use hard
film antifouling. Resistant to high
pressure felt from mud and silt,
hard film products leach biocide
over a period of time without any
of the film of the paint eroding.
3
COPPER BASED
Copper-based antifoul
products work particularly well
on new or recently restored hulls
where a very smooth application
can be achieved. Despite their initial
high cost, a copper-based coating
can last a number of years.
REGIONAL CONSIDERATIONS
Oban and Largs are well known to
experience heavy barnacle growth,
whereas Southampton Water
experiences much lower levels
of fouling due to the large amount
of industrial traffic passing up and
down. It’s well worth researching
what’s proven to work in your area
and talking to the professionals.
Deciding which jobs to take on yourself and
which to hand over to a yard is, for most, a
question of time and budget, and all of the
checks here can be done by a yacht owner
if they are so inclined. Some safety-related
checks, however, should always be tackled
by a specialist. While it’s easy things like
a liferaft that you hope never to use, their
functioning correctly is absolutely critical,
so it’s not worth the risk. They include:
^ Gas check
^ Fire extinguisher servicing
^ Fuel and oil testing
^ Liferaft, EPIRB, Jonbuoy
and lifejacket servicing
^ Rigging check
Be sure to follow service schedules and
keep records as any future buyer of your
yacht will probably want to see them.
Finally, expiry dates on flares should
never be ignored.
It’s likely that your mast has remained
up over winter. Getting up the rig, giving
it a thorough clean and a look over is a
worthwhile exercise but it shouldn’t be
mistaken for having a professional rigger
check that it is safe. When you’re at the
top of the mast, install and reconnect the
anemometer, which should be taken off
over winter as they always seem to suffer
damage from birds. Check your masthead
lights are working and that any masthead
blocks are running freely. If you have a furling
headsail, check the mechanism is running
smoothly at the top of the mast as well.
Rigging
Replace the through-hull
transducer with the blank plug.
