So
we’re back in lockdown again from Weds 18 August and it appears
this could last a few weeks. From the boating perspective it’s
better for
this to happen now
than later, as we move into Spring next month. It seems it was
inevitable that the delta variant would hit our shores and while it’s
all too easy to criticise aspects of how NZ has handled the situation
(eg
the way in which rooms for quarantine are allocated) our infection
numbers are remarkably low. If we had the UK’s infection and death
rates, then based on the population difference we’d be having 2,665
new infections and 8 deaths daily. While there are sad stories about
people having problems returning to NZ, haven’t these people
largely created their own problems?
Back
to the subject of Cruising and
firstly engine servicing.
We’ve
used TerraCat for servicing our Cat 3208 10.4L V8 diesels as
they’ve had a very knowledgeable engineer
who knew our boat well. However he recently
left TerraCat and after
considering our options we
decided to change contractors to Marine Propulsion (MP). The main
reason for this is it’s highly desirable to have the same person
doing your servicing as they get to know the peculiarities and history
of your boat. We weren’t convinced TerraCat could offer this
continuity. So far we’re impressed with MP. The engineer who’s now doing
our servicing is actually one of MP’s directors (so
unlikely to be leaving)
and he suggested coming on board a week before the service to
familiarise himself with
Rapport and discuss our expectations – impressive service. We
wanted somebody who will not only change oil and filters, but
proactively look for potential issues and provide advice on
preventative maintenance. So far we’re very satisfied with our
move. For example he found that two pencil anodes in our heat
exchangers have not been getting replaced because access is
restricted and standard anodes can’t be used. Solution: he’s
going to cut some standard anodes down so they fit and then some
protection will be better than none. He made suggestions re filter
changing frequency to save us cost without compromising performance
as well as suggesting we use our spare filters first and replace them with new ones in order to turn the spares over. That’s the kind of engagement and
service we want.
Useful
tips
1.
Barometers
Most
of us have nice shiny brass barometers on one of our bulkheads and these
should certainly be considered useful beyond ornamentation. So how
should we use them?
The
barometer’s indicator needle should be reset each morning in order
to monitor changes.
If
pressure rises or falls 1.6 to 3.5Mb over a 2 hour period it’s
warning of a depression.
If
pressure rises or falls 3.6 to 6.0Mb over a 2 hour period it’s
warning of Force 6 winds.
If
pressure rises or falls more than 6.0Mb over a 2 hour period it’s
warning of Force 8 winds.
A
drop in pressure of 15 or more Mb in a 24 hour period indicates a
weather “bomb” is imminent.
As
a matter of interest the world’s average atmospheric pressure is
1013Mb

Protection from sharp hose clips
Have
you ever cut your hands or fingers on the sharp ends of stainless
steel hose clamps? I sure have and to avoid this have fitted
Clamp-Aid hose clamp safety guards. These are flexible silicone
sleeves that easily fit over the ends of hose clamps to provide
protection. Cost is about $32 for a pack of 20.
3.
Mounting fittings on gelcoat surfaces
At
some point we all need to add fittings such as an aerial mount to a
gelcoated surface. What most of us do is drill a hole in the gelcoat,
put some silicone in the hole and onto the screw and Bob’s your uncle
right? Wrong. Silicone has a limited life of around 5 years, so at
best water will eventually find its way in to the cavity and migrate
into the substrate beneath the gelcoat. The correct way to do this is
to drill a hole much larger, in both diameter and depth than what is required for the screw, fill the hole with epoxy and then drill the
screw hole in the epoxy. This will ensure that moisture doesn’t get
into the substrate beneath the gelcoat. In
any case silicone sealants are not suited to marine applications and
we should use marine
sealants like Sicaflex 291, 3M4000
or Bostik
Simson MSR Construction Adhesive.

Paint aerosols
You
normally have some paint left in the aerosol after completing
your job. In order to re-use the aerosol hold it upside down and
press the nozzle until all residual clears out of the nozzle. Then store aerosol upright.
We weren’t planning to do much cruising during August, but hope the lockdown is over so we can start serious cruising again from mid-Sept.
