NAVIGATION                    Back to Valhalla's Mooring Page

(REV 27 June 2017)   

On this page I will add items concerning navigation.  They will appear as my imagination, inspiration and time permit.  Subjects are welcome!


Terry's Topics

Since September 2014 I have been sending to a distribution list of yachts (now totaling 82) topics of interest (in my opinion), mainly concentrating on computer navigation but not limited to that.  The topics are now formatted as a recapitulation list with download links.  The current Terry's Topics list is shown HERE and will be updated when a new one is distributed.  If you want to be on the distribution list, please send me an email to that effect. You can opt out at any time with another email.  A description of using this website is here.

Joint Typhoon Warning Center GE feature

            An essential part of seamanship and safe navigation is to be aware of the weather conditions, especially when in an area threatened by a storm. The Joint Typhoon Warning Center (JTWC) provides warning of tropical systems in the Northwest Pacific, North Indian Ocean, Eastern Pacific, and Southern Hemisphere.  A new feature to display forecast storm tracks on Google Earth Is described here.  (Updated 1 Jul 13)
