On a slightly different topic, be sure to be aware once you get into Mexican waters that your plotter will lie to you.. we were always showing anchored some distance inland.
I'd say night time landfalls without radar are a no-go...
Good advice, this. Most paper & e-charts of Mexico's west coast (Pacific side & Sea of Cortez) are based on scant US Navy & British Admiralty surveys, some of which date back to the 1880s! Bathymetry is limited, many hazards are uncharted or misplaced, and the entire swath from Ensenada to Bandaras Bay has chart datum errors exceeding 2nm. Here's an excerpt from the (sole) NOAA chart of the northern Sea -- a vast area, generally shallow, with lots of hazards & a huge tidal range:
Note the excess of detail.
Anyone wanting more tools can supplement their charts with the chartlets from Gerry Cunningham, and/or Heather Bansmer.
Per anchoring, I gathered from books and blogs that holding is generally good, with packed sand being the most common bottom (suggesting a plow-type). A heavy enuf claw should work, too. Estuaries can be silty, where the claw would be preferred, and there are anchorages with plenty rock & kelp, which may make anything short of a 200# fisherman's tricky to set. Fluke-type anchors make good lunch hooks in the sandy areas, but the large tidal currents (or nighttime katabatics) in most of the Sea can trip them when you aren't looking. We're planning a ~35# Rocna, Manson, or Mantus, on the theory it can best handle the range of bottoms & will reset quickly if tripped.
Thanks Zeehag for the 'lots of chain' advice.
