      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

      Moderation Team Change   06/16/2017

      After fifteen years of volunteer moderation at SA, I will no longer be part of the moderation team. The decision to step aside is mine, and has been some time in the works but we did not wish to announce it in advance for a number of reasons. It's been fun, but I need my time back for other purposes now. The Underdawg admin account will not be monitored until further notice, as I will be relinquishing control of it along with my administrative privileges. Zapata will continue on as a moderator, and any concerns or issues can be directed to that account or to the Editor until further notice. Anyone interested in helping moderate the forums should reach out to Scot by sending a PM to the Editor account. Please note that I am not leaving the community, I am merely stepping aside from Admin responsibilities and privileges on the site.

AIS Transmitting

11 posts in this topic

So I bought a Standard Horizon radio with AIS and hooked it up to my plotter (thread on fiddly NMEA wire complaint which see). It works beautifully and will prove useful. Have to replace the wirenutsmad.gif

 

We took a mini cruise last week and all the contacts were commercial until on the last day clicked on a contact and saw something like

SAILBOAT- xxxxx (can't remember the name)

LENGTH- 54'

COURSE- 098

SPEED- 6.7 Kt

 

Of course at the time we were shy reaching under chute at about 12-14 kts and we all simultaneously said "Damn, we need a transmitter"- Pure multihull ego talking. Don't really need it, and should have bought a dedicated device if we wanted one.

 

My question is does anyone have real word experience with current draw when transmitting? If we are going to indulge our egos we need to be able to transmit, and our electrical capacity is laughable except when the sun is shining.

 

As well, the contact information shows things like destination etc. Is that part of having Class A equipment or can class B transmitters do the same. How does the data get entered- we saw a lot of variety among the commercial contacts as to how much information was displayed when we clicked on a contact.

 

And why is a $350 iPad running $40 worth of software so much better than an $1,800 plotter- except for seeing the screen in sunlight and needing a waterproof case, better resolution, faster zooms, easier to scroll, tap screen to enter a waypoint you name it better. Thats my latest rant.

VALIS has the ACR "Nauticast" Class-B transponder, and the current drain is essentially 0.3A @12V. No doubt the current spikes up when it transmits, but the transmit bursts are extremely short, with many seconds between. I could not (easily) measure a difference between transmit enabled or disabled power consumption. As a bonus, with the transponder you get a built-in GPS. The downside is that you *need* to install that GPS antenna somewhere, or the transponder won't transmit (it's in the rules for Class-B AIS).

Tucky,

 

The reason the iPad is so much better than a dedicated Chart Plotter is simply volume. I used to be in the "biznez" and with volume comes low price and higher quality (if the vendor wants it, which Apple does). Unlike boats, were a hand-built beauty is almost always the "better" boat. In computers and the semiconductor components that they are built from you need massive volume to get the price down and the quality up. There is no such thing as a "hand built" computer, at least not one that's worth much.

 

When you add to the volume advantage the fact that the things are general purpose and relatively easy to write software for, it's a no-brainer.

 

Just as folks now use computers with a printer attached as a cash register for a lot of stores, I would guess that in the future folks will use a tablet with a WiFi link to the sensors as their primary navigation tool. Oh wait! A bunch of us already do! I still have a chart plotter, but only because the boat came with one. Next time around, that power hungry had to use device goes off to Craigs_list_Land.

Tucky,

 

I just installed a Raymarine e7D chart plotter on our new sailboat that mirrors the display to the iPad and iPhone, and can be controlled from both iOS devices.

 

here are my observations, contrary to the crowd. I use the iPad for most everything but find it isn't all that workable on a sailboat. certainly not, as compared to my new dedicated chart plotter. it isn't easily mounted, affixed to a stable and waterproof attachment. the display is difficult to read in sunlight, and the keyboard a nightmare to use in anything resembling a rough sea. I can read the new Raymarine display perfectly with sunglasses on, whereas my iPad is totally blanked out. I like the sun-readable display, the touch interface, and the integration of multiple data sources such as Radar, AIS, sonar, NMEA 2000 and 0183 instrumentation, and it also affords me the ability to go anywhere on the boat and have full control and display of the chart plotter. of course, it is sealed from spray and easily affixed where convenient. the iPad ... not so much.

 

I like the idea of the iPad but don't think it is ready for prime-time ... not quite yet. I do enjoy the added utility it affords. I can watch videos (including FLIR IR data and remote camera) on the Raymarine but really prefer the iPad for everything else. think weather retrieval, email, web access, videos, music, and books. I think the Standard Horizon (and others) trend of integrating Windows and WiFi at the chart plotter is a mistake. makes no sense, to me, when you have an iPad at the ready.

 

love the cost though ...

I have a CTRX Class B box from True Heading in my F31.7 and I've not encountered any battery drainage issues. The spec's says 6W on average; http://www.trueheadi...RX_20090128.pdf

Couldn't agree more, and apart from being an outstanding plotter the iPad does all the other stuff a traditional navigator doesn't do..

What's that smell?

 

 

 

Whiff o' steer droppings, I think.

Because I just can't resist doing so...

 

My primary navigation device at the moment is an iPad2. I have three GPS handhelds on board, but so far this trip they've only been used to update the DSC-enabled VHF and as an anchor alarm (which they still do better than iNavX - or I haven't found the way to make iNavX do it properly, more likely.

 

I used it in the sun today while wearing sunglasses and had no trouble. I needed to move it to get it out of the glare from time to time, but that wasn't difficult.

 

My wife found it easy to use when she spelled me at the tiller. (Her sunglasses did have more trouble. Still usable.)

 

And now that we're docked in Friday Harbor (needed shore power for an emergency "do this work thing", plus the chance for showers and laundry) I'm sitting in the cockpit using it to do the preliminaries of that work while waiting for the laptop to finish charging... on the iPad.

 

But I don't have any Cheetos. I think there might still be some Oreos, though - close enough?

If you aren't at a dock you are way too close.

Tucky,

 

The reason the iPad is so much better than a dedicated Chart Plotter is simply volume.

BV

 

 

My assumption is that Apple has essentially written all the structural bits- how the swipes/zooms etc. work, all the things that make the iPad so functional. I guess the app writers just put their layer on top. I think that is the brilliance of the whole concept- and the volume makes a huge difference

 

The problem for Garmin/Raymarine etc. is having to spend time on these basic bits over and over. Just the moving the cursor function is frustrating- goes too slow then jumps too fast, doesn't work smoothly at different levels, you name it. I picture some software type re-inventing that wheel, while the iPad writer is one hundred steps beyond it.

 

I had a silly app on my phone that fogged the screen with droplets when you breathed on it, and then made a perfect squeak and cleared as you wiped your finger across it. Of course my plotter does that too on a foggy day.

Part of the reason they suck with sunglass is that the screens are polarized.

 

As for glare, get a nusheild
