Antennas/Amps for WiFi, Aircards, Cell Phones

I am seeking advice/experience from the group on the purchase of marine antennas to improve the reception range for wifi, aircards, and cell phones. I have read enough and talked to a few vendors (Wilson) to understand the myriad of products but not sure what will work best at the least cost. Also, I realize there is not a single antenna for all devices – aircards and wifi since they receive/transmit “data” may work fine without an amplifier; whereas, an antenna for a cell phone (voice) may need an amplifier to get the expected results. I currently have the Verizon mifi hotspot (4510L) because Verizon seems to have the best overall coverage on the east coast. This works well but I would like to improve the reception when in remote locations where a weak verizon signal exists. Another case is when moored or docked at a marina that has wifi

iPad-Raymarine Integration – NMEA-Seatalk-WiFi

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

iPhoneSailing – iPad

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. Jeff Church

iPad-Raymarine Integration

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

iPad – Navionics and Raymarine

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

Procedure for Installing Additional Insulation to Early Refrigerators

August 29, 1997 Some early Catalina 380″s may have void areas between the hull and the back of the refrigerators present insulation.¬ Voids area will be found on both side as well as the frontal areas.¬ Additional foam must be added to the bottom area, some sort of temporary cofferdam will be required in this area.¬ The following procedure will increase the “R” value of the refrigerator. Please Take Note: This procedure will require great care in the drilling and injecting of the foam.¬ Caution will be required when drilling thru the refrigerator outboard face to the void area.¬ Drilling too deep will contact the hull or hull liner.¬ Use caution when injecting this foam.¬ It can become very messy stuff.¬ Clean with lacquer thinner or acetone immediately.¬ All drilled hoes to be 1/4″ diameter. Step 1.¬ ¬ ¬ ¬ ¬ Remove range Step 2.¬ ¬ ¬ ¬ ¬ Remove

Companionway Hatch Cover Repair

I wanted to share with all of you the outcome of the companionway hatch cover that I wrote about a few weeks ago. Here is what I said at the time. Mine, a 2000, hull 226, I guess is what Warren described as the “old” slider version, which is all smoked acrylic. I have a similar problem ‚Äďhatch sticks and, depending on the weather, it is almost impossible to open and close. Two companies in the yard (general maintenance and a fiberglass expert) have looked at the hatch and the hatch frame and both concluded that the ‚Äústicking‚ÄĚ problem is caused by a structural problem with the framing. According to both, the cabin hatch frame has a wood base that the hatch frame screws into. According to one person who looked at the framing, a certain amount of non-orthodox adjustments were made to build up the frame to accommodate the

Bridge Clearance

Posted by: “Paul and Carol McManus” 5/20/2009 The bridge clearance for my tall rig is 61′ 3″. My 380 specs say the standard rig is 4′ shorter than the tall rig. My clearance also includes a 2′ 7″ for a VHF antenna. So if have a typical sailboat VHF antenna. Your bridge clearance should be about 57′ 3″. If don’t have a VHF antenna then your wind vane is the tallest point and you can subtract another foot for a clearance of 56′ 3″. By the way I used 5′ 9″ for my water line to base of the mast measurement. I have the Charleston Spar conventional mast. All these dimensions were taken with the boat hauled and the mast unstepped.
