For boats
General
about tides and currents on Tuamotus:
The majority
of the atolls have at least one break in the reef called pass. But only some
passes are wide and deep enough to permit a cruising sailboat to enter through
them.
The current
runs strong in and out of these passes. How strong is current depends on a lot
of
factors
including the moon cycle, wind and wave conditions outside, how big the atoll
is, how
narrow the
pass is, which way the pass faces, and how many passes atoll has.
If the wind
opposes the current, there can be large standing waves. And if there are strong
winds or
large swell, there can be as much as 8 knots of current. So it is always best
to aim to enter the pass at slack or near-slack tide.
Some passes
are east-facing, and these passes will be dicey on the outgoing current. Some
passes are
west-facing, and these passes will most dicey on the incoming current.
Entering /
leaving the atolls become danger when:
1. A strong wind opposing a strong
current. This is just classic wind-against-sea and can
always
produce uncomfortable and/or dangerous conditions. It is best to try to plan
your
arrival at an unknown pass in mild conditions and in good light.
2. When the
wind is blowing hard (over 20 knots) out of the SE thru West
3. When the
wave heights are high (over 1.5
meters) from the SE thru West.
Strong
winds and/or waves from East push a large volume of water over the reef into
the lagoon, and the only way for this huge volume of water to get out is
through the pass. In this conditions (strong wind for several days) there may
be NO SLACK AT ALL.
In Tidal Tables or any other Tide software or
information available in internet on Tuamotus there are only few points with
information about HW and LW (the biggest atolls). If you are between them you
can use a simple interpolation to calculate HW and LW time. It works, not very
precise but it does.
So, there
is no easy way to predict current or slack water in passes, but you can follow
this tips:
- Slack is about 1-2 hrs after HW
and LW
- Never sail through the pass
during the night
- Observe the water and waves in
the pass when approaching from the see by binoculars
- Just try to enter / leave, but
if the current is to strong go back and wait until condition will change
(usually 2-3 hours)
The atoll
and the pass
There is
only one pass into the lagoon of Tikehau. Passe Tuheiava lies 7 miles N of the main
village; This passage is located on the W coast, 100m wide, 4m deep, no marks
inside the pass and the current can easy reach 6kn. It is not easy going pass –
be care.
Inside the
pass there is a route to the Tuherahera village
marked by green / red and cardinal buoys.
The main
village Tuherahera is 7NM South from the pass, you will see houses and concrete
wharf.
The Marina
The best
option is to moor inside a small inner harbour (go along the long wharf on your
left), pass a small entrance to the basin and there is a 40m long floating pier
dedicated for visitor yachts. The depth near the pier is about 2.7 meters, but I don’t
know what depths are in the entrance to the basin. It’s look that 2m draft is
guarantee. There is no water or electricity on this pier. I don’t’ know it’s
free or paid. There is a place for 4-6 yachts (more if you moor long side to
another).
Formalities:
Tikehau is
not a port of entry, no possibility to check in or out.
Fuel
Not easy to
buy. Ask in the shops.
Water
No official
tap point on the wharf. There is a tap inside the hangar – ask local people for
access. You have to buy that water (payment in Town Hall – 10XPF per liter),
than tank to your jugs.
Gas
Bottles
available in the shops (not all the time). No possibility to refill no
Polynesian bottles.
Cash
No bank, no
ATM. Payment in US dollars is rather not accepted.
Provisioning:
The town
has three shops. Limited products, especially vegetables and fruits.
Other:
A church,
post office, city hall.
Airport:
Airport is
located at the end of the village. Easy access. Flights to Papeete.
For crews
No WC or
shower on shore.
Tuherahera
is a very friendly but small village.
There is a
church, be there during Sunday service – nice songs.
Fees
Anchorage - no fees
Berthing to
the wharf – no fees
Water – 10XPF per
liter
