This blog is about planning and preparation for a circumnavigation of the world in a 39-foot sail boat followed, hopefully, by a diary of the actual circumnavigation. You can track the progress of Pachuca by visiting http://www.pangolin.co.nz/xtras/yotreps/tracker.php?ident=VNW5980

On Tuesday I purchased a GPS receiver (No brand, part number BU-353) that is in the shape of a flying saucer about 25mm in diameter. It is heavily magnitised and can also be attached with a suction cup. It has a USB connector.
After two hours of fiddling I got the system to work. The receiver sends NMEA-0183 sentences to the laptop. A driver supplied with the receiver manages the USB port in the laptop. CMap 4 was configured to look for the data at the particular port (com4: in my case).
The receiver performs as advertised. It had no trouble acquiring satellites from inside a house with a tile roof, or on a shelf at the navigation table inside Pachuca. It achieves fixes in amazingly short time.
On Pachuca CMap 4 displayed the location of the boat at the 11th double-boat bay of the NE side of D jetty. We checked and sure enough Pachuca is in the 11th bay from the end.
The unit cost me $129 AUD (i.e. Aussie dollars).
I've also ordered a USB-DB9 conversion cable to attempt to connect the Trimble NT200D GPS to the laptop. I figure that redundancy is worth the $49 AUD cost of the cable.
The next task is to visit the PC shop and get a transformer to allow me to run the PC off the boat's 12V system.

|Pachuca's Circumnavigation Plan V2.5|
|From||To||Dist Nm||Sailing Days||Stop Over Days||Total Travel Days||Depart Date||Arrival Date||Core Storm Season||Avg Speed in Knots|
|Port Phillip||Whangarei NZ||1600||24||7||31||04-Apr-08||28-Apr-08||Jan-Mar (Nov-May)||2.78|
|Honolulu||Juan De Fuca||2290||34||58||92||05-Aug-08||08-Sep-08||Jul-Sep (May-Nov)||2.78|
|Juan de Fuca||San Diego||1100||17||3||20||05-Nov-08||22-Nov-08||Jul-Sep (May-Nov)||2.78|
|Avg Speed Knots||3.1|
|Distance Sailed Nm||28257|
|Days Under Sail||378|
1. Multiply sailing distance by 1.2
2. 80 nm per day travel
Except for Falklands-Cape Town-Fremantle legs where I assume 120 nm per day due to favourable current and winds
Parenthesis includes periods affected by early or late seasons.
The affected area includes: Fiji, Samoa, North island of NZ
Callao, Peru (near Lima)? It is supposed to be the best anchorage on the Westen side of South Amierica
