Difficulty Entering my first way points ?s

Difficulty Entering my first way points ?s
My first waypoint Port Manatee reef inside Tampa Bay lat:Lat:27.658 Lon:~82.574 image

I think I received bogus coordinates image these next coordinates handwritten paper where a tad better however was unable to delte a 0 an an 8
There’s a dozon waypoints named Port Manatee reefs at this site maybe there all close an bunch of reefs
All in the same vacinity?
https://www.tidespro.com/fishing/us/florida/tampa-bay


while attempting to enter the first set of coordinates I’m unable to delete this 8 an unable to delete this 0.

When I enter what I was able to the waypoint did actuely show up on map as a route from my current location inside the house.


I have the Ray Marine element HV12. currently using the free charts. Haven’t opened or activated the light house charts yet bc my next cruise is in 5 months, so I’m preparing my way points an routes.
Thanks for advising.

You are trying to enter degrees, minutes and seconds, but the Ray is expecting degrees and minutes with decimal. So, 27° 39.700' and 82° 34.800' (42/60 = 0.7, 48/60 = 0.8). It looks like the Ray wants three decimal places, so you have to enter zeroes at the end to make it happy.

[Edit] If I convert directly from your decimal degrees rather than the minutes and seconds I get 27° 39.708 and 82° 34.794 - going to three decimal places as it seems the Ray likes. Three decimal places of minutes is about 6 feet/2 meters, while one second is about 100 feet/30meters [/Edit]

Example Latitude 27 39’ 42”N the 27 is degree’s 39’ is Minutes an 42” is seconds N is north
27° 39.700' You divided 42seconds into 60seconds equals .7
Then added three decminlpoints to get the 700 which the Ray will accept. So only the seconds (the 3rd #)
Needs converting.

2nd example Longitude 82,34’48”W
82.34’800W
Ray has made this a nuisance could there be a way in settings to reconfigure how the Ray accepts coordinates?

Additionally what are the #s inside the parenthesis? Example 27 39’42”N (27.6618)
Thanks PippaB for explaining.

[Capt. Steve1]

coordinates apparently must be 3 digit # not seeing way to adjust in settings. are there websites that publish the coordinates w/ seconds already divided by 60?

[Pandor]

Surely, Capt. Steve, you jest. You do realize that there are an infinite number of waypoints? Which ones do you want converted to decimal minutes?

are you saying I have to convert every way points seconds the 3rd #?
the Tampa Florida area inside bay,nearshore an offshore. I thought my new MFD coordinates that need converting was just the seconds the 3rd #.

I’m not sure if this is what you are looking for but this links to a converter for Lat/ Long formats

https://www.fcc.gov/media/radio/dms-decimal

[Hobby]

Here is a more full featured Lat/Long format converter.
https://www.omnicalculator.com/conve...ates-converter

This allows you to enter the coordinates in DD-decimal degrees or DMS or DDM format. The result is displayed in DD, DMS and DDM.
If entering into a Raymarine chartplotter, use the DDM result- ie-45 degrees 56.876 minutes

[Capt. Steve1]

Starting to understand the unstandarized coordinates.

I can find Florida Panhandle coordinates here. Example training reef first bridge rumble of Destin,FL


I prefer the Tampa bay website they provided both types of coordinates.



https://www.google.com/maps/d/u/0/vi...652784492&z=14
Unforchantly they only provide the Lat an Lgn (backwards) I can convert these coordinates
To degree/minutes/seconds that I can enter into the RayM.

I like this site here for doing the conversion
https://gps-coordinates.org/latitude-and-longitude.php

initially this seams to be all backwards to me right now jumping though hoops to find a location. At least I have the basic understanding an the tools at my fingertips.

Here’s my conversion from decimal Lat 30.37031 Lgn -86.49371
To degree minutes seconds Latitude:30 22’13.1154 Longitude:-86° 29' 37.3554"
Previous coordinate entries in the Ray Marine seconds was only 5 digits hopefully this conversion w/6 digits will be allowed rounded up/down.


I feel this current process to be very laborious hopefully I will get the hang of coordinates find better websites ect. definitely will be saving to removable memory.
Next I’m learning routes.
Thanks to
PippaB, Hobby for advising

These are all just different ways to represent the same thing.

27.6618 is decimal degrees (no minutes or seconds, just decimal parts of a degree).

If you take .6618 x 60 = 39.708' (60 minutes to a degree, so you are multiplying the fractional degree to get minutes)

and if you take .708 x 60 = 42.48" (60 seconds to a minute, so multiplying the fractional minute to get seconds).

Capt Steve,
Are you sure that your Raymarine MFD allows you to enter coordinates as DDD MM SS.sss? In other words as degrees, minutes and seconds.

As far as I know, Raymarine MFD’s only allow the format of DDD MM.mmm. The format is degrees and minutes with the numbers after the decimal sign(ie the .675 of the 34.675), giving the thousands of a minute. You can multiply .675 times 60 to convert the thousandths of a minute to seconds but that is not necessary.

If you are using this google map link to source your waypoints, when you highlight the desired waypoint, the DDD MM.mmm format is displayed on the left side in the pop up box. Then you can enter that directly into the Raymarine MFD.

Hope this is helpful.

Darn I thought I had it figured out. yes Hobby you are absolutly correct the Ray Marine accepts DD/MMM.mmm


so from the google webpage I enter the DM # is really DDD MM.mmm correct?
previously I was converting these coordinates to dec minutes seconds is this why the longitude on the ray had the 0 as first digit?
Rays surport says the same thing.
DDD MM.mmm. I'll get back on it an report back.
the advanced RayM manuel doesn't mention DDD MM.mmm just Lat an Lgn.

thanks Hobby.

Not having much luck finding a decent webpage w/ maps/charts of tampa bay, Florida artificial reefs like on previous images I posted.
https://ocean.floridamarine.org/boat...art_reefs.html
no chart just a list
the first 5 google searchs for tampa florida artfical reefs where crumie. No charts/maps
today is not a good day finding maps charts w/ reefs in Tampa.

Yes, that is correct

The 0 as the first digit is because longitude goes from 0 degrees to 180 degrees. When you enter longitude of 10 to 99 degrees, the display needs to see a 0 before the two digits of longitude, so the system sees a three digit number. I imagine if you wanted to enter 6 degrees of longitude, it would be entered as “006”.

Rays surport says the same thing.
DDD MM.mmm. I'll get back on it an report back.
the advanced RayM manuel doesn't mention DDD MM.mmm just Lat an Lgn.

Yes, The manual does omit the most important part of entering coordinates, the DDD MM.mmm part.
It sounds like you are making progress.
