ReefsNWrecks Detail Nautical Reef Charts

About The Maps

The Reefs and Wrecks Detail Nautical Reef Charts present a never before seen view of Florida's reefs and wrecks.  These maps present an exciting new view of the bottom, showing the exact size, location and topography of structures in very fine detail.  Fishermen and scuba divers will love the ability to see the exact relief and position of each underwater structure, allowing them to drop anchor exactly where needed, without wasting time searching around or fishing over sand.   Do not spend thoursands of dollars on a new "bottom view" sonar unit.   Just open our Detail Nautical Reef Charts and see everything at once without wasting time and gas scanning back and forth for hours.   Spend more time on the high relief structures that fish love.

We have divided up the website by Florida county.   We currently have the counties that are featured on tabs on the top of the screen.   Other reefs in other counties are being added all the time so please check back if you do not see your county listed.   The green shaded counties below have reefs we have currently scanned.   Just mouse click on the county you are  in interested in.


What are Detailed Nautical Reef Charts

The picture on the left below shows the lack of detail of a standard NOAA chart.   You can see that the reef is shown only as a small light blue half circle and labled as a Fish Haven with a minimum allowed depth.   It does not show any detail as to the location of structure, which is imperative for fishing and diving.    So we scanned the bottom of reef areas with sonar for many hours and then processed the data to produce our Detailed Nautical Reef Charts.   (Example seen on the right).   Now you know exactly were to go fishing or diving, no hunting around looking on your depth sounder.   Move around and check out all the structures in the area not just one or two waypoints you got from a friend.  See your boat positioned right on the charts in real time as you move around and anchor up.



 How To Use The Charts

Brighter reds have greater profiles (peaks) while light blues have lower profiles. The color key scale on the right indicates the respective reliefs. The left side of the map indicates the GPS latitude (North-South) and the bottom of the map indicates the GPS longitude (East-West) coordinates.   Each reef contains a numeric key, the date it was deployed, a description and the relief in feet off the bottom.   Know what is on the bottom before you drop anchor, and when you do, drop it right where you want it!



Formats available

The basic file available is the GPX file which contains the latitude and longitude of all the waypoints associated with that particular reef.  The waypoints are chosen to be in the center of each large pile of reef material, or a number of interesting spots along a particular ledge or wreck.   Each waypoint contains a description of the material or reef that is at the waypoint, the depth and relief off the bottom.   The GPX user manual explains how to use the file and can be downloaded for FREE by selecting (SAMPLE) by any GPX file on any reef screen.   (Example of GPX file below.)  Most GPS units will accept an import of a GPX file.   Check with the manufacturer of your GPS unit.


The KAP format is the same format as all standard NOAA raster charts and can be used in many chart navigation programs.   As can zoom in to a smaller and smaller area, our detailed reef and wreck charts will open and display exactly what is on the bottom.  All the charts show details with resolution down to .001 minute (6ft).   This format is used with OpenCPN on a PC or with SeaIQ Open on an iPad/iPhone or Android device.  The KAP user manual explains how to use the file and can be downloaded for FREE by selecting (SAMPLE) by any KAP file reef screen.


The KMZ format is used with Garmin hand held GPS units and on a PC with Garmin Homeport and Google Earth.  The KMZ user manual explains how to use the file and can be downloaded for FREE by selecting (SAMPLE) by any KMZ file reef screen.  



The PDF Format is formated to let you print out the pages and bring them with you fishing or diving.    The pages are laid out with a description of the reef and a table of callouts with deploy data, reef description and height off the bottom or relief.   Place the pages in plastic sleeves or laminate them for use on the boat.    Bring them with you on a friends boat or your own if you want a simple hard copy way to view the detailed reef charts.  The PDF user manual explains how to use the file and can be downloaded for free by selecting (SAMPLE) by any PDF file reef screen.



The QDC format (Quickdraw Contours) is used with Garmin marine GPS units.  Refer to the Garmin website to check if your marine depth sounder is compatable with Garmin Quickdraw Contours.  The QDC user manual explains how to use the file and can be downloaded for FREE by selecting (SAMPLE) by any QDC file selection.
