Mira - Network Diagram

Image
By

 A few people have asked for more details about out network on-board.  Instead of trying to describe it, and because I should have one anyways, I decided to create a Network Diagram.

So far, the network has been working great.  On occasion, the 2.4 GHZ radio in the MNC-1250 stops responding, however I am working with their tech support to get to the bottom of it.  We have that device mounted upside down to the "ceiling" of what I call the network area in the owners cabin.  I have a suspicion that it maty be overheating as it it not sitting in the orientation it was designed to be in. 

As it turns out, I have a spare 12v computer-type fan that I am going to wire into the 12V fuse block in there and mount it to the router and see if that makes a difference.  I also went into the configuration settings and turned down the output power of both the 2.4GHz and 5GHz radios, since the signals do not have to go very far to cover the boat.  This should also reduce the amount of heat generated.

Have a look at the diagram and let me know if you have any questions!

    Very nice! Question: Since the B&G, Victron, PW Data Hub .. are all connected via NMEA, why are they also connected with Eternet? Since PW Data Hub has LAN connection, would connecting the Data Hub only to the WiFi router be enoogh to pass the data fm all NMEA equipment to the WiFi netwotk?

      Only limited data flows across NMEA, therefore, a network connection is needed if you need to bridge that gap. We try to hardwire as much as possible to a) make it more reliable and b) leave more bandwidth/reduce latency on the wireless.
      I would highly recommend the iPad app AquaMarine. It can connect to the NMEA of LAN feed that the DataHub creates, so that app shows real-time boat and wind data (somewhat limited, but it's still very handy)

Victron Isolation Transformer - How to lower the output voltage

By
Re-configuring a Victron Energy isolation transformer This is a companion article to a YouTube video  covering the same topic. What are they and why do I need one? Victron Energy isolation transformers are often used on boats that connect to shore power in order to provide a means of providing isolation between the shore power and the AC power that exists on the boat.  The transformer sits in between those two worlds and isolates that two power supplies through magnetic flux and an air-gap. The reason this is needed on a marine vessel is because without it, small leakage currents can flow between the earth ground for shore power and the "earth ground" connection on the boat, which is usually connected to water through a propeller shaft, out-drive, sail-drive or sacrificial zincs. That creates a loop and that small leakage current greatly accelerates any galvanic corrosion that naturally happens. Current flows through the water because of the salt content, or even in fresh-wat...

Raising the dinghy, easier!

By
The Davit System The Vision 444 comes with a Carbon Fiber Davit system that is used to hoist a dinghy.  As time has gone on, some of the exact specifics of the davit system have evolved and changed slightly, but for our boat (Hull #11) and the ones near to it, this is how it operates.  Two Main Steps First, after attaching the dinghy to a forward and aft attachment line, the davit arms are raised; pivoting on axles which mount the davit to the transom of the boat.  This step is accomplished by attaching a line which runs through several blocks to the starboard, aft power winch.  Pressing "2" (low speed) on the winch power buttons and raising the davit into its full upright position, where it can be lashed to the boat with Dyneema loops. Second, is to raise the dinghy to be close under the horizontal beams of the davit arms.  The dinghy attachment lines, that are attached to the dinghy's bridle, run up through a fixed block at the end of the davit arms and then t...

Vision 444 - How to (hopefully never have to) use a Storm Sail

By
 How to use the Storm Sail on a Vision 444 My fellow Visionary Pierre on Umbono reached out recently wanting to review the steps for deploying the Storm Sail, since he was forecasted to be in less-than ideal sailing conditions in the next day. What better opportunity to write a blog article! This is going out quickly to support Pierre, but I will come back and add pictures and maybe link a video later. Preparation Keep the Storm Sail and everything you need for it somewhere where it is easy to get. We keep ours in the large lazarette under the Cockpit table seating. If you think you might need the Storm Sail, you probably should have the jacklines put out too.  The system we use to deploy the Storm Sail reduces the time we need to be forward, but wearing a life vest with harness and being clipped into the lazy jacks is the way to go here. Our Storm sail is in it's own bag with the following: A port sheet attached to the clew with a bowline A starboard sheet attached to the cle...
