Mashnee systems

This is an exhaustive list of Mashnee's various subsystems.

Electrical

12-volt

Batteries

Two batteries run through a battery switch. Batteries are both house and engine; no distinction possible with current wiring.

Solar Charging

Yes

Electronics

Wind

Raymarine ST60 windex. This is no longer supported by Raymarine, so if it goes kaput we'll want to replace it. The mast wiring runs into a small white Raymarine box which is located in the ceiling just to port of the mast. As of May 2019, the connection was made via a screw terminal domino block.

NMEA 2000 network

There is a SeaTalkng backbone, which is an NMEA 2000 network with non-standard connectors. As of May 2019, the backbone was installed behind the Axiom MFD.

Radar

Another near-future thing (as of May 2019). We have the radar (B&G Broadband 4G Radar); we are looking for a way to install it in a 1902-compliant manner.

AIS Transponder

• Vesper Marine XB-8000 Class-B AIS Transponder NOT CURRENTLY INSTALLED. Another near-future thing (as of May 2019).

Radios

Fixed VHF

• Uniden UM525 Fixed Mount VHF Marine Radio
• Owner's Manual: File:Uniden UM525 VHF Radio.pdf
• MMSI Number: 338236803 (assigned via SeaTow)

Handheld

• Uniden WHAMx4 Wireless Handheld Auxiliary Microphone
• Owner's Manual: File:Uniden WHAMX4om.pdf
• Communicates wirelessly with the fixed-mount VHF radio
• The wireless recharging cradle is mounted just to starboard of the companionway

Magnetic Compasses

There is a magnetic compass which is placed in the starboard lazarette. When it is deployed it is mounted on a small brass rail at the foot of the companionway. The two wires plug into the bottom of the sailing instruments box.

Note, this compass cannot be trusted. Compasses do not take hard knocks well, and there is no guarantee that its placement is not in a magnetically pathological location. This compass can be used for relative heading hold, e.g. maintaining a number. However, the absolute values are not to be trusted at all. [KDS]
