Position & Passage Report Watch
Report Watch is a positive action service originally
designed for yachts and other small-craft on passage or
cruising in the BRUNEI
BAY RADIO service area.
The daily (evening in
BBRs service area) emailed position/passage
report sent to Brunei Bay Radio combines with a daily
(morning in BBR's service area) emailed YOTREPS position and
weather report, to create twice daily contact.
The 1200 UTC report informs BBR of the overnight
location - often at anchor for cruising yachts - or
passage plan. The 2200 UTC report to YOTREPS provides
position, weather and intentions to indicate the latest plan for
that day; at anchor, exploring ashore, or underway to a new
destination, with course and speed if underway.
Voice contact can also
be established if required.
This service is commonly used by yachts cruising alone
or in small groups in isolated parts of
service area, and for yachts - or
small groups of yachts - making long passages, usually as
part of their SE Asian cruising area arrival or departure.
This service is based
upon participating yachts carrying specific on-board communication and safety
equipment. Because of this, the BBR position report watch
can have a very definite notification procedure to alert
an appropriate MRCC if there is no contact from a yacht on
the watch list.
It is essential to have
a dependable email service on board. SailMail, Winlink are
preferrable. Satellite based email is also feasible.
A small monthly fee
applies. SailMail members receive a discounted fee.
Yachts and small-craft
that wish to join this service should contact
at least two weeks in
advance of departure, so there is time to setup the
reporting routines and to check that on-board communication

Navigation in this region:
When looking at Lat and Long positions, remember there
is a significant difference between the WGS84
datum used by electronic VECTOR charts, such as C-Map -
and also Google Earth - compared to the datum used by
paper charts, and by electronic RASTOR charts (which are
a scan of paper charts). It DOES NOT WORK to use a
Lat/Long derived from C-MAP/Google Earth (ie: VECTOR
chart - WSG84) and plot that directly on a paper or
RASTOR electronic chart without making the correction.
Paper charts always show the correction required to
convert between the two datums.
Old charts always create a much better opportunity to
hit “uncharted” obstructions, reefs etc. Paper charts
are constantly updated (ie: monthly) with small and
large corrections. There are summarised in Notice To
Mariners. Some marine chart issuing authorities - eg
Australia - have a service to send automated emails of
Notice To Mariner chart updates for their paper charts.
See the issuing authority websites for details.
There have been substantial chart updates in recent
years in SE Asia - especially in parts of the
Philippines, such as Palawan. Be sure to update your
electronic and paper charts with the latest information.
Notice to Mariners - and emailed updates from the chart
issuing authority - contain the information to manually
update your own paper charts. Electronic chart
suppliers release regular updates for their products.
Stay current to avoid incidents.
The pirate version of C-Map that is commonly available
and swapped between cruising yachts is an early 2000's
version of C-Map. Considerable upgrades to paper and
electronic chart information have occurred since then.
Considerable changes man-made features such as
lights/beacons, shore facilities, channel markers etc
have occurred since this copy of C-Map was liberated.
It is prudent to have up-to-date information. Using this
pirate version of C-Map increases the risk of a
It is important to have the latest detailed charts for
harbours, ports etc. For paper charts, this means the
particular charts for that port, or series of ports,
correctly updated with Notice to Mariners. For
electronic charts, the details are normally there
already (if using an updated copy), but it's essential
to click to get to that detailed level to see all the
information. For example, here in Brunei, a number of
yachts have hit the training wall that runs just below
the surface along one side of the main shipping channel,
because A - they did not look at the detailed C-Map
chart display and/or B - they had the old pirate copy of
C-Map that does not show the additional set of channel
markers and other changes.
We are a
C-MAP agent and a paper chart agent. If you need the
latest paper or C-MAP chart upgrade, please email. We
can have these ready when you call into Brunei, or send
them to you most places in SE Asia. If you need to spend
money on C-MAP or paper charts, please support Brunei
Bay Radio's services for small-craft, by buying from us.
(Software On Board) is an Australian made navigation
software created by a yacht sailor who does delivery
work and was determined to have a good system for a
realistic price. It uses C-MAP charts. SOB can display
SailMail's GRIB weather charts as an overlay on
SOB/C-Map, plus AIS info, MOB plots etc. Email us if you
wish to purchase a copy. We also have convenient and
innovative small PC options (the size of a car stereo)
which are robust and can run SOB and C-Map, plus all the
usual on-board PC needs, such as a stereo, CD/DVD player
