I came across the following link that shows how to configure your iPad if you are using the Brookhouse iMux:

NMEA and Seatalk routed via WIFI
I might have this figured out.
Navoinics for iPad:
Connects to Raymarine NMEA and Seatalk streams via standard WiFi router
Upload/download waypoints and routes
No real-time instrument repeater
Navionics charts included in price
$35 USA. $50 USA & Canada
INavX:
Requires hardware such as iMux for WiFi and to translate Seatalk to NMEA – $250 approx
Supplied with NOAA raster charts. Navionics or others are addl $50 approx
Upload/download PLUS real-time instrument repeater capabilities
$50 with NOAA charts
I’d appreciate any corrections to the above. It would be nice to find out that the less expensive Navionics will repeat instruments, but I have not found any evidence of that.
Users report that iNavX has much better functionality overall. Even at $350 for the total package it is relatively inexpensive compared to the cost of an ST70 Multi repeater or a below decks chartplotter, assuming

If you are interested check out the forum at iphonesailing.com. That’s where I found the answers to many of my questions. Both the iNavX and Navionics users on that forum were very helpful in clarifying the hardware and software required to interface both apps to the E80. Also, there is much good info regarding the capabilities of each app.

If there’s one thing I’ve learned, you can’t have a productive technical conversation based on fuzzy hypothetical options, and shifting objectives.
I can find no evidence that the mobile Navionics application “understands Seatalk”. What may be misleading is that the Raymarine Raytech RNS software, which “understands Seatalk without a mux”, uses Navionics charts. Brookhouse also stipulates the Program iNavx as a requirement for using their iMux combiner, again using Navionics charts. Navionics Mobile supports Plotter Sync which enables the wireless exchange of waypoint and route data. The following link is to a YouTube video by Raymarine which clearly demonstrates what is exchanged.
I don’t share the assessment that the Brookhouse iMux is for “somebody who is starting from scratch.” It was designed, built and is marketed to address the question and requirement you initially detailed…”Is it possible to access Seatalk information on an iPad thru its wifi connection and either

I did a little more research. Called Navionics and Raymarine.
Navionics says that their iPad app is primarily intended as a stand-alone app and told me to contact Ray regarding interfacing with a chartplotter. That seemed odd considering that Navionics developed Plotter Sync and incorporated it into their app less than a year ago as an interface to Raymarine plotters.
Ray says that they have “stepped away from Plotter Sync” because it was not reliable. I suspect that another reason might be that it competes with their new E7 chartplotter’s WiFi connect features.
My takeaway is that the Navionics app is probably useful as a nav tool and it MIGHT interface, but since I’m looking for an instrument repeater I’ll be looking at the iNavX app instead. iNavX is a bit more expensive, but it gets good reviews from folks who are using it as a plotter and real-time repeater

I’ll chime in here as I have been doing a lot of research to upgrade my A/H. This is all Raymarine info, as I have no experience or knowledge on Furuno units.
I have a 1999 C380 with (factory?) installed ST6000 and a Type I linear drive (electric ball-screw type ram drive) mounted under the transom step and connected to an Edson arm (this part is readily available from Edson, and is specifically designed for linear drive units).
The ST6000 is an old unit with no other unit other than the control head, where all electrical connections are made. It does not handle heavy seas very well at all, and forget quartering seas. It will steer to a waypoint (if properly connected to a GPS), or a wind angle, as well as a simple compass course. It is a basic A/H.
The last (now retired)

Mainsheet, August 2009
These are a couple ideas from Bob Bierly who captains CMON WIND, C380 #255 out of Reedville, VA.
Forward Shore Power Inlet
All C380’s came with a 120 volt shore power inlet, usually mounted on the transom on the starboard side. This is not a convenient place to run dock power to when traveling, particularly if you prefer to dock bow first into a slip. To simplify this, I installed a 30 amp shore power inlet in the anchor locker facing forward in the vertical fiberglass face under the windlass controls. Photo #1 shows the location.
Running the #10 by 3-wire 120v cable back to the electrical panel was simple because that area behind the wooden panel at the forward end of the vee berth is directly open to the molded chase along both sides of the boat. Just run the new cable along the starboard

XM Satellite Marine Weather

Hull #: C380
The following article is from Steve Dublin famous for his 380’s ocean racing and Mainsheet front cover – Warren
About six months ago, I upgraded the GPS/Chartplotter on my Catalina C-380 “Caretta” to a Garmin model 3206. The new chartplotter was mounted in the cockpit on the pedestal guard. It was networked to Garmin’s GDL 30A XM satellite marine weather receiver, which I installed below deck by the distribution panel. The installation process was very straightforward once I learned how to splice an ethernet connection. The watertight ethernet connectors are too large to snake down a pedestal guard tube.
However, Garmin sells a separate connector kit. This allows you to cut off one connector, snake the wire through the tube, and remake a watertight connection. The weather receiver has its own mushroom-type antenna that I mounted on the hoop

SSB Radio Installation
Steve Dublin
August, 2007
Hull #: C380 #84
Editor’s Introduction– As I spent many of my younger years as an active radio amateur [ham] and virtually all of my work life in antenna & microwave engineering, I feel some degree of justification for the comments you’ll see sprinkled throughout the article below [apologies to author: Steve Dublin]; I hope they’re helpful– that’s the intent!
One general comment by way of clarifying some terms. The two popular versions of transceivers used by sailors are “Marine” and “Ham” types; they are both capable of SSB transmissions. Their functional distinction is principally that of frequency of operation. Marine SSB units are limited to certain frequencies as dictated by the FCC.
Ham units were limited to other frequencies, called Ham bands, but newer Ham transceivers are capable of operation on both marine and Ham frequencies, so there’s a distinct advantage for
