If you have more than just a GPS to connect to your Mac I am recommending the ShipModule Miniplex lite. It supports three NMEA inputs and one output (which can be connected up to four devices).

The third input port can be used for an AIS receiver as it supports the high speed AIS data (at 38,400).

The Miniplex lite plugs right into the USB port of your Mac.

WiredBoat sells these units for US$179..

Note if you need Raymarine Seatalk capability then consider a MiniPlex 42 USB or Bluetooth model.

Both MacENC and GPSNavX offer help accessed on their respective "Help" menus.

Or the help can be found online..

I am pleased to say that I have now released v1.0 of PassagePlus, my ARCS-compatible navigation application for OS X. Information about the product and a download page are available at http://www.windvector.com

I will of course continue to make enhancements, so any constructive feedback is welcome.

Hello

I just found gpsdX and gps2ge on this homepage
http://robin.darroch.id.au/gposx.html

The first application is a daemon for one GPS device to be conected to several applications.

The second application is a GoogleEarth viewer to monitor actual GPS positions.

Will or does GPSNavX and MacENC already support this daemon so that I can use the best navigation software with other GPS related applications?

Thx in advance.

Is is possible to have multiple windows of the same chart, at varying zoom levels? Something like this:

As MacENC does use vectorgfx and layers is it possible to set up in preferences the boats draught and MacENC does colorize in transparent light red or any other color the regions in the chart that are critical to this depth?

If not is such a feature planned in future versions?

Or is this just a bad idea?

Thx for any reply.

I was having a chat with a friend of mine who skippers racing yachts, and we came up with what I think would be a great feature for GPSNavX / MacENC.

Already, you can record telemetry from the GPS and instruments to store a track of your progress as you sail or motor, but all you can do is export it, or view it as a line on the chart. What would be seriously awesome is if you could replay that track with your boat position in relative time. In other words, at the end of a sail, you could play back the entire voyage at, say 3x speed, and what your yacht zip along a track.// pretty cool.

OK.. now, imagine that you're sailing, you could import a "track" that you've created or a route, with speed data and play that back at 1x speed while plotting your real course on the chart. This would enable you to:

1. See a "ghost ship" of where you were on a previously voyage, vs where you are now, comparing how effectively you're sailing against a previous journey (great for racers)

2. Upload a passage plan that takes into account tidal flows and track your progress against that.

I've talked in previous posts about GPSActionReplay, a Java application that allows you to replay GPS tracks (in GPX format) saved from your instruments. However it's not particularly intuitive, and does require tweaking to get maps set up etc..

Just a thought.... anyone else find this useful?

Prolific has released their driver software for BU-303, BU-353, MR-350 GPS and Intel Macs. If you have an Intel Mac and one of these GPS receivers please install this driver (PL203_1.2.1)

Do you know the WorldSpace Receiver System ?
I'ts a Radio receiver system by satellite for radios and data (meteo charts, etc...) rather unexpensive and very powerful, but... apparently only on Windows :-((((
Does anyone have other informations ?

I am happily using GPSNavX, but should I get MacENC?

Am I right in understanding that if I used MacENC, I could throw away GPSNavX and happily use MacENC for both raster & vector charts?

Is GPSNavX better in any way at handling raster charts than MacENC is?

Thanks
