COMMODORE’S REPORT Chris Williams
Hi again to everyone and welcome to 2020.
I hope everyone got a break in over the silly season and is ready for the year ahead.
Well so far we have been straight back into racing with the Total Yacht Care summer series on
Wednesday nights and our new rum race sponsor for the summer season is Hesketh Plumbers
with Northland Spars and Rigging continuing to look after the Friday twilight series.
There has been a good turn out of boats and a few newcomers which is good to see.
January has been a busy month with two fantastic events, the first been the tall ships organised
by the Russell boat club. What a fantastic event with Opua boats doing very well with a special
shout out to Cees on Nexus for a 5th place in the classic invitation.
The second is obviously the Bay of Islands sailing week, a huge event for Northland and especially
our club as we are lucky enough to host the event. There is a great little blurb on how this event
got started on their website under the ‘about us’ tab.
This year there was a huge turnout of boats with I believe over one hundred and forty boats com-
peting. Opua boats had a good haul of prizes and trophies especially in the E division where 5 of
the 9 boats were Opua boats. The results are up on the bayofislandssailingweek.org.nz website
I would like to acknowledge on behalf of the Opua club, the sailing week committee and
volunteers for the amazing job that they have done, as we know these events don’t just happen
and there is a huge amount of organisation that goes into this event.
Last but not least we are about to say goodbye ‘for a short time hopefully’ to Violet our amazing
bar Guru who is off on maternity leave as of the middle of February. From all of us we wish you
all the best.
While Violet is away we have Elizabeth filling in and somehow we have tricked her into filling in
for Sheila for a month as well so please introduce yourselves and we will try not to scare her off
too quickly .
Thanks
Chris Williams

BOB MCDAVITT’S WEATHER CORNER
Northland surf, waves and swell - a tale of two coasts.
In late January the swells along the east coast of Northland were enhanced thanks to a deep low well
off to the east., travelling south, and focussing the swells so that the larger swell misses the Northland
Coast.
Forecast Wave Height for Monday 20 January (issued 4 days beforehand,
Thanks to www.surf-forecast.com/weather_maps/New-Zealand for this graphic
Waves can be divided into “wind (or sea) waves” which are the result of local winds, and the swell
which comes in from the surrounding Ocean and may have a direction different from the local winds.
The surf and breakers that affect the beach usually twist their direction to be onshore, depending on
the local topography. Their height depends on the waves and swell.
Tides can be larger than normal when the moon gets closer to planet earth (KING TIDE). Another
factor that may affect (and may flood or help erode) the coastline is STORM SURGE that may directed
outwards from a storm system even further than the swell.
In enclosed waters such as the Whangarei, Kaipara, and Hokianga Harbours, and to a large extent, the
Bay of Islands, it is unlikely that the wind generated waves ever exceed two metres. This is because
the winds to generate such waves would need to be either a steady wind of 70 km/hr or more (a very
rare event in Northland), or would require a much longer fetch than the enclosed harbours provide.
There is a known relationship between steady wind speed and wave heights over the open sea.

NORTHLAND SURF, WAVES & SWELL
‘MetBob’ McDavitt
For more exposed coastlines, the most probable wave heights for a given wind speed over a typical
fetch length in New Zealand coastal waters of about 500 km are as follows :-
Average Wind speed Associated Significant Wave Height (in metres) at 500km of fetch
10km/hr or 5 knots up to 0.5m= smooth
20km/hr or 11 knots up to 1m= slight
30km/hr or 16 knots up to 2m =moderate
40km/hr or 22 knots up to 3m=rough
50km/hr or 27 knots up to 4m=very rough
75km/hr or 40 knots up to 7m= high
100km/hr or 54 knots up to 11m=very high
125km/hr or 67 knots up to 13+m=phenomenal
Map of average swell is From NIWA website
niwa.co.nz/natural-hazards/hazards/waves
Much of the swell that affects the west coast
of New Zealand originates in the ocean to the
south of Australia. On the west coast of
Northland, the most frequent swell direction is
from the southwest, occurring nearly 40
percent of the time. The frequency of swells of
less than one metre is about 20 percent, while
swells over two metres occur approximately 35
percent of the time. Heavy southwest swells
are particularly noticeable in winter and spring.
On the east coast of Northland, swells from an
easterly or northeasterly direction tend to
predominate. These can originate from tropical cyclones or lows to the north of New Zealand or from
anticyclones out to the east. Of all swells observed on the eastern coast the frequency of those less
than one metre is about 40 percent, while for those greater than two metres is 8 percent
So, in Northland, on the west coast the swell conditions are good for fishing around 20% of the time
and are good for surfing around 40% of the time. For the east coast, the swell conditions are good for
fishing around 40% of the time, and surf is only “up” around 10% of the time.
How level is the sea? NIWA offers daily updates of the sea-level for 17 spots around New Zealand at
niwa.co.nz/our-services/online-services/sea-levels to help you see any King tide or storm surge.

BAY WEEK 2020 Manuela Gmuer-Hornell
Congratulations to Opua Cruising Club members, sailors, boat owners and volunteers.
What a week we had during the 18th Bay of Islands Sailing Week. Record entries of over 140
boats entering and 137 racing - exactly 100 more than the inaugural Bay Week in 2003.
We also reduced our landfill waste by 3/4 - what an achievement!
The Wetherly Bus took out first in their division and had four generations on board for
racing. Go the Kiff family.
We held the Tornado Class Nationals - won by a past member, Dive Lineham and second by
another past member Wayne Limbrick. Well done guys!
