00Z
Weather Chart |
These charts were obtained from the
NOAA National Weather Service (NWS) web. Each chart displays the NWS
surface weather analysis for the area of the cruise. 00Z is the time of the
chart data or midnight Greenwich Mean Time (GMT) also known as Universal
Coordinated Time (UCT). The "Z" or "Zulu" designation is a throw back to my
time as a weather forecaster in the USAF (1965-1971). The eastern time zone
of our departure point is five hours behind GMT, four hours when allowing for
day light savings time. Therefore 00Z on June 26 corresponds to 8:00 PM or
20:00 Eastern Daylight Time (EDT) on June 25. Therefore the 00Z charts each
depict the weather conditions we were encountering shortly before sunset on
date prior to that of the chart. Bermuda is in a different time zone than
the east of coast of the US and local time in Bermuda is one hour ahead of
EDT. |
Rhumb Line |
The Rhumb Line is a course between two
points of constant true heading. When you sail the Rhumb Line between two
points you set your compass course at the departure point steer straight to
the destination. Assuming you have accurately determined the magnetic
deviation of your compass, the magnet variation of your cruise area (and
assuming it doesn't change significantly the between the departure and the
destination), the boat does not make significant leeway, and the ocean
currents do not set you to one side or the other of your intended course you
can set the autopilot on the Rhumb Line course and eventually your
destination will appear over the bow. Of course none of those assumptions
are ever valid for an extended cruise, therefore the course will have to be
periodically adjusted based on the conditions encountered. However the
Rhumb Line is still the preferred course for most small vessel navigators on
trips of less than 1,000 nm. It is not the shortest course to the
destination (the Great Circle is the shortest), but it is easiest to
determine and navigate. One the conveniences of the Rhumb Line is that it
can be drawn as a straight line between two points on a Mercator Projection
chart. The Rhumb Line course depicted on the weather charts is not accurate
as these are not Mercator Projections, but it's close enough for web work. |
SSB
Radio |
The Single Side Band (SSB) radio has
become the standard for long distance communications for voyagers as well as
shore-bound HAM Radio enthusiasts. You don't need a HAM License to use a
SSB Radio, but you do to use the HAM frequencies available on SSB. We used
both the HAM and non-HAM frequencies on our trip. We used the HAM
frequencies for email and for placing non-commercial telephone calls to the
US and Bermuda. We used the non-HAM frequencies to maintain contact with
the various cruiser nets and organizations (e.g., Bermuda Harbor Radio) who
were monitoring our voyage. |
Dark and Stormy |
The preferred tourist drink on
Bermuda. A mixture of Gosling's Dark Bermuda Rum and Ginger Beer. It's
sweet and potent (at least the way I pour one). The rum improves your
disposition and the ginger beer keeps your stomach settled (remember your
mother giving you ginger ale when you were sick as a child?). The
combination makes for boisterous, but short party. |
