      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Remapping South Florida after Irma

Recommended Posts

Fellow South Florida Sailors- we have the opportunity to help remap South Florida waters after Irma. As we all know, there was a lot of shifting of sand during the storm so the charts need to be updated now. 
We can now join Navionics and NOAA to remap South Florida waterways after Hurricane Irma. #RemapSouthFL

I'll be joining! Who's with me?

It is a pity that ALL the data gathered by boaters is not in some central registry and accessible to all boaters and scientists as an open source project.

We know more about the moon and mars then we do about 71% of this planet....

Remap?

How about "initially map" in the case of lots of our waters?

Yes, we have charts, but they have soundings on them done by people on a boat that had no electric light bulb on board. Because they did not have those yet.

The amount of detail that is gathered every time we run around with depth finders going is pretty staggering to think about. Glad someone thought, "Hey, what if we gathered it all?" Crowd sourced charting is a pretty cool idea. I'll probably participate with at least two of our boats.

Would you try to take a boat drawing 3' into Shell Creek at low tide? Sure looks like you'd hit a two foot spot no matter which way you tried.

It's actually possible. But would be a good idea to have a local aboard while trying it.

Careful about that 13' deep spot. That means "along the N shore." On the other side, it's going to be closer to 10 inches at low tide.

There are three areas upstream of the RR bridge that are actually 20 feet deep. Anyone wanna guess where they are?

No, it's not really 2' deep approaching the US 17 bridge. I can get a 3' draft boat through there at the lowest tide.

Oh, and if you're really hoping for 5' of water going by Green 21 in the Peace River, you'd better do it at mid tide or higher.

All those details could be filled in by running a log on a morning fishing trip.

I wonder how (or whether) it will be possible to correct such logs for the state of the tide? Lots of those places that show as drying at low tide really do, but I drive right over them at high tide. Making choices based on what I do at high tide would be a bad idea at most tides.
