Technical Details for Boat Geeks
-
Builder, Dimensions and Capacities
The boat was manufactured by Pacific Ocean Countries Trading Association (POCTA) Suzhou, Jiang–Su Province, China, is 48’10” in length with a 15’ beam and a 4’7” draft with a displacement estimated at 54,000 pounds with an advertised gross/net tonnage of 41/33 tons respectively.
The boat carries 1,100 gallons diesel fuel and 370 gallons fresh water and uses something less than six gallons per hour of fuel at about 7.5 knots.

Engines and Generator
The vessel is equipped with twin John Deere 4045TFM50 diesel 150 HP main engines. The engines are turbo-charged, mechanically controlled with Morse engine controls and VDO analog gauges, water-cooled through a heat exchanger, and mated to ZF 220 transmissions driving opposite rotating 26” 4-bladed propellers.
The vessel is equipped with a single diesel Westerbeke 10.0 kW generator. The generator powers the Air Conditioning, Daily 110 and Inverter circuits when operating. See AC Power description for more information.

DC Power
DC Primary Power: Three LiFePO4 Lithium-Ion batteries of 315Ah each in parallel for a total of 945Ah available at 12 volts. The batteries serve as the primary DC house source and also serve as the batteries for AC power through the inverter. While connected to shore power, the Lithium bank is charged by the inverter/charger.
While underway the LiFePO4 battery bank is charged by the engine alternators through Balmar External Regulators configured to charge Lithium batteries.
Each engine has its own starting battery which are charged by DC-DC converters from the Lithium battery bank when underway and by a separate Newmar battery charger while on shore power or generator.
-
AC Power
AC Primary Power: The vessel uses 240V 50 AMP power which is split into two 120V circuits. One circuit is solely for the air conditioning systems. The second circuit powers a Daily 110 circuit and the inverter circuit.
The Daily 110 circuit is for high amperage systems such as washer/dryer, battery charger, hot water heater, ice maker, etc.
The Inverter circuit powers all AC outlets, microwave, TV and more. The inverter circuit also provides charging power to the Lithium battery bank while on shore power or generator.
The Westerbeke 10 kW generator powers the Air Conditioning, Daily 110 and Inverter circuits when operating.

Internet and WiFi
The vessel is equipped with an IT network with Ethernet and Wi-Fi consisting of the following components:
Pepwave Max Transit router: This router provides the vessel’s Wi-Fi network and can use multiple sources for Internet connectivity: Sim Card; Wi-Fi as WAN, other WAN sources (such as Starlink). The Router has two Wi-Fi access points to ensure good Wi-Fi throughout.
Starlink: The vessel is equipped with a Gen 3 Starlink antenna located on the SeaView antenna mount at the top of the radar arch and connected to the Pepwave Router as the wired WAN input. The Pepwave Router uses the Starlink as primary Internet access and transmits data over the vessel’s Wi-Fi network.

NMEA 2000
The vessel has a NMEA 2000 Network includes:
- Two Garmin GPSMap 7612 Chartplotters.
- Camino-108 AIS.
- SIMRAD Autopilot Controllers
- AirMar WX200 Weather Station
- Actisense NGT-1 NMEA2000 to USB Converter.
- Yacht Devices YDEN-02 NMEA 2000 to Ethernet Gateway. Enables PCs, iPads, and other navigational devices to receive NMEA 2000 data either over Wi-Fi or via direct Ethernet connection.
- Fusion Stereo with NMEA2000 wired remote.
- Actisense EMU-1 Engine Monitoring Unit connected to the generator’s engine temperature, oil pressure and alternator voltage gauges to allow remote monitoring of those engine parameters.
- Digital Yacht veKonvert – Victron VE.Direct to NMEA 2000 gateway. Provides Victron Smart Shunt data to the NMEA 2000 network.

Navigation
Primary navigation is conducted with an Apple iPad Pro running Aqua Map and Navionics, combined with Garmin GPSMAP 7612 chart plotters. These are connected to the vessel’s Wi-Fi network enabling access to NMEA 2000 data such as depth, wind, GPS, course and AIS.
Aqua Map is fully functional with chart and Expert subscriptions which provide access to USACE surveys, marine forecasts, AIS integration and more.
Navionics autorouting capability is used initially to preview routes.
The route’s GPX files are then easily uploaded to Aqua Map for review and modification.
The reviewed route is then easily uploaded to Active Captain for transmission over Wi-Fi to the Garmin chartplotters.
Once loaded on the chartplotters, the routes can then be used to drive the autopilot through the chart plotters.
