|Short link to NGA NIMA Pubs|
There are many wonderful resources on the NGA website, formerly NIMA, formerly DMAHTC, formerly DMA, formerly HO, formerly NO etc... ie the home of Bowditch and many other important navigation references. And with each new change in the agency it gets harder to find these valuable references, so we have made a short link to get there: starpath.com/navpubs. Save this link, it is a valuable one

You can now listen to the VHF weather reports as streaming audio. These are not from NOAA but they do announce the services here: Listen to Weather Radio online. Should be a nice bookmark for those who do not have a portable VHF or weather radio at home.
The unfortunate cover of this othewise excellent book
|New book on Oceanography and Seamanship|
...well, it is not really new, but we just recently discovered it was still in print. We thought it was out of print for many years or we would have been carrying it and recommending it all along. Very few outlets carry it and we thought it was gone, though we rely on our own old copies often and for diverse queries. If you care about how the wind and ocean affects your boat, this is a unique and wonderful resource. Gives real numbers without being too technical. See Oceanography and Seamanship by Van Dorn
Online chart viewer from NOAA
|NOAA Chart Viewer settling in|
NOAA has had a nice new electronic chart viewer on line for some time, but the link to it has come and gone and moved around. Now we seem to be consistently find it here NOAA online chart viewer. This is a good place to see what any US chart looks like and in fact there are links to download a full working copy for the electronic charting system (ECS)of your choice. They will work in any of them and they are FREE. The download link is on the main index page linked above under the name RNC = raster navigation charts.
Also note that NOAA has settled in on the names as well. A RNC is a bitmap or raster chart in the BBS format, whereas the ENC (electronic navigatin chart) is a vector product in for example the S-57 format. So RNC = bitmaps (pictures of real charts) and ENC = vector (formulas that recreate a chart from outlines, fills and text overlays). If we apply this nomenclature to other prodcuts we would say that C-map brand charts are ENC and softchart brand charts are RNC.
