I didn't see a response but if you have an updated file for the 20 fathom track Ill try uploading it to navionics!

Send me a DM and I'll send it to you

Those aren't dd-mm-ss, they are dd-mm.mm

It is measured in tenths of minutes, not in seconds, if that makes any sense.  GPS is silly sometimes - many different users (ships, sailboats, airplanes, car navigation, etc) use different integers to depict the same position. Most common that I've seen are: dd.ddddd (Google maps and a lot of terrestrial users), dd-mm-ss (sail boats, some charts), dd-mm.mm (most commercial mariners, most navigation charts). There are also a few other systems with specific ideas that not many people use.  Most modern devices let you choose which system you are most used to, between the three that I exampled anyway.

"Should the last part of the latitude (39°25.53'N) be entered as 053 or 530? Or what?"

So what's the answer? The navionics app, for lat. has 2-digits in the first spinwheel, 2-digits in the second, and then there are three more spinwheels with 1-digit (0-9) in each. See my post above for the screenshot. Do I have to do a conversion from dd-mm-ss to dd-mm.mm before entering into Navionics? But then the number of digits in the interface is 7 instead of 6. So confused.

I finally got it figured out. The way-point map on the CDFW site...
https://wildlife.ca.gov/Conservation/Marine/Groundfish#287201301-20-fm-line

... lists two lat/long coordinate formats for each way-point:

lat_dd/long_dd (aka Decimal Degrees)
lat_ddm/long_ddm (aka Degrees Decimal Minutes)

Neither of which were the format I was basically familiar with (Degrees, Minutes, Seconds) and I had no idea there were other formats in use.

The Navionics App uses ddm, but it's confusing because they don't label it as such and they have 3 digits at the end of the number string on their coordinates-input screen, while the coordinates provided by CDFW only have 2. For example, for a CDFW-provided 6-digit ddm longitude of 39°12.19'N, Navionics has 7 characters to select (with only the 6 provided by CDFW), and then the question is what to do about that. The answer turns out to be just use a ZERO in the last position/selector.

Issue solved.

Glad you got it sorted out. It's all about using the same units on both sides. 

I created the 20fa line GPX file from the DFG data, converting it as you mentioned:

I'm working on another converter (lost my original) to make them into Navionics format.  Should be ready today.

I've got a trailer that came "free" with my HobieCat, with no license or registration.  Prior owner said he had tried contacting prior owner but was never able too.  Would anyone have advice on how to remedy this, I'm not even sure I can read numbers off the trailer or not (will check next time I visit it).

Wow an active catfish bit a swimbait?!  Crazy!

On CBS this morning they were talking about it and mentioning that some commercial crabbers participated in a time release buoy deployment system trial and that they were happy with the results.  Trying to lend credibility to the plans they have mentioned in prior statements as a possible solution.  Sounds expensive, but would allow longer seasons.  Still costs will go up either way I'm sure.

Whats the reason for removal ?
Is it a danger to boaters who are going to fast and not looking where there going in the fog ?

Just cost savings.

I've seen lots of hull protection posts and none of the solutions seem permanent.  Some kayaks have that replaceable skeg, that's probably the only solution that I've seen that looks permanent, but still needs to be replaced depending on use. 

That said, I'm also not sure why people feel they need hull protection.  I'm careful with my kayak, not perfectly all the time, it has some scrapes for sure, some gouges.  But I'm not wearing away any spot on my kayak, because I don't drag it except on sand or dirt. 

When I wheel to the water I get the nose as close to the water on my wheels and then lift it off on to the ground.  When I launch, I lift the back end and walk out, not scraping and the nose floats the yak until i'm ready to jump in and go.  If i'm at a launch ramp I do the same, except facing backwards.  I have hullavators, so it comes off the side of my truck, and on to the ground, with the rear of my yak already in the water.  Launching by lifting the front and walking out and then I either launch backwards or turn it.

I really like this design, although you have to BIY: https://www.dfw.state.or.us/MRP/recompression/docs/FishGrip_HowToMake.pdf

The videos on its usage just looks like what i'm imagining doing on my kayak:




I have some thin poly-rope and I want to mount it on a spindle or some way I can just clip the rockfish and then descend it by dropping overboard
