Bob Agramonte of La Conner, WA, asks:
Do you plot your position on paper chart per hour basis (time, speed heading)? Or is this info written in your log? GPS can and has gone down.
We have been logging our Latitude and Longitude each hour - along with magnetic course and speed. We have not been plotting it on paper as our computer handles that for us. We have a lap top computer with Raytech navigation software - plus we have the Raymarine chart plotter which is independent and has its own chart cartridges. We have three GPSs and a spare computer with all duplicate software. The computer and handheld GPS is stowed outside the wheelhouse and would not be subject to lightning damage. We also have paper charts aboard. I could not imagine a series of failures aboard our boat that would render us unable to receive GPS and I don't really think that the GPS system is going to go down - every satellite - all at once. If it did - we'd have to dead reckon and use our Radar - we have no sextant aboard.
Has our war made any changes in your route plan?
There have been hostile people in Somalia, Yemen and Sudan for years - so there is concern. We've been watching this carefully and don't see any real evidence that a transit of the area will be unsafe.
