|Ever since I
brought my first PC computer on board, I have found the MS Excel one
of the most useful of the standard software products on the computer.
I've used Excel to maintain lists (food and supplies), forms (logs, crew
lists, sight reductions) and perform many other functions. Eventually
I started to use the computational capability in Excel to automate a few
navigation functions. Initially it was to perform the arithmetic
required on a celestial navigation sight reduction form, then maintain a DR
position from the Ships Log. As the computations grew more complex
they exceeded what could practically be accomplished with the standard Excel
This is an integrated VBA application for many navigation calculations
including celestial navigation and maintaining a Ships Log.
- BoatRecords. This is an integrated
VBA application that can be used to maintain an inventory of everything
I store onboard as well as a log of maintenance functions performed.
- GPXConvertVBA. This VBA program
converts the waypoints, routes and tracks in a GPX file to either a
Raymarine Waypoint Transfer Utility Excel workbook or to a Comma-Separated
(CSV) text file. I principally use this program to transfer route
waypoints from OpenCPN to my Raymarine C-120 MFD.
- Winlink Log v1.3.
This template creates a log workbook for connections to Winlink. In
addition to providing a place to record these connections the workbook
calculates the connect time for each PMBO to provide an indication
of any connect time issues. It also records a connection bandwidth value
(very rough) to provide some indication of which PMBOs may provide a better
connection for a given position and time.
- SailMail Log v2.1.
Similar to the Winlink Log, this workbook provides a place to record
SailMail connections and it keeps track of connect time to that system.
- Ship Weather
Reports v1.4. This template creates a workbook in which ship weather
reports received from SailDocs can be parsed and sorted to identify those
ships (if any) that are close to your vessel position. There are a number of
steps required to use this template so I've added a page of instructions on
the use of the Ship Weather Report
- SOB PastTracks. Software On Board
(SOB) is a PC-based chart plotting package that I have used in much of my
electronic navigation. SOB generates tracking files that capture most
of the ship data (course, speed, depth, wind, etc.) at small increments.
I wanted to use these files for analysis of some passages made on Sarah, but
I found Excel could not process the data as created by SOB. So I wrote
another VBA application to convert these files into Excel-friendly data.
I use this program to create Excel workbooks in which I can present the data
graphically, such as on this
This program was developed for an older version of SOB. The tracking
logs generated by more recent versions of SOB can be parsed into an Excel
worksheet without the use of this program.
- BoatProvision. This application
can be used to develop a provisioning list for a passage based on the
passage parameters, a menu plan, and a set of recipes.
- Waypoint Management. I use a mix
of chart plotting system to navigate Sarah. I've created a set
of Excel workbooks and a VBA program to manage those worbooks to help me use a common set of waypoints for each of
these disparate systems.
This is a very limited program, and probably not of much use to others.
I developed this program while anchored in Great Sale Cay waiting for an
easterly gale to subside. It was a quick and dirty way to create a
single copy of the numersous waypoints in my Bahamas Cruising Guides (Dodge,
Pavlidus, and Explorer) for the three chart plotting packages I was using at
the time (SOB, Fugawi and Raymarine C-120). I plan to develop a
completely different Waypoint Management package using GPX files and
integrating it with the GPXConvertVBA program.
