Current Standards
NMEA 0813
Well known
Easily hacked
NMEA 2000 (N2K)
Proprietary
Standardizes PHY and cabling
Must register and assign PGNs
Must buy into the cartel
New Standard
Wireless out of the box (using Flutter Wireless)
IPv6-based too much data on wire? Too confusing?
Open Standard
Website to register vendor and data codes
Benevolent dictators of standard
We approve vendor and data codes
Protocol Details
Easily tied into standard Ethernet
L3 Protocol
IPv6
Put data directly into IPv6 extension header (header 60 maybe)?
Data grouped into multicast addresses
L4 Protocol
Existing one out there in
RFC
land?
SCTP for life critical
UDP or own raw protocol for normal traffic

Product Line
Coral
Products
CoralWind
Wind, sail, weather station related instruments
Maybe a separate CoralWeather
CoralPower
Engine management
CoralHead
N2K gateway, hub for flutter devices
One version could have wifi
CoralPatch
Flutter device that takes an existing device's N2K data and converts it to wireless
Notes
Solar Power
Sort of an open version of TikTack product line (now Raymarine)
Doesn't work 24×7
In-line power
Tap into power going to device being measured (with CoralPatch)
Startup Resources
Protocol standard developer (embedded, protocols, C language)
IOS/Android app developer for reading data
Website, outsourced
Test equipment
N2K protocol reader equipment
Office or hacker space with room for permanently located hardware
Budget for marine conferences (travel, entrance fees)
Benefits
Wireless from the start
And Internet of Things based mentality
Make it easy to put everything on a network
Cost less than products with N2K markup
Allow other companies to develop products around the protocol
Challenges
Reverse N2K without getting sued?
N2K has huge market share and is industry standard
Mostly towards recreational market
Getting the word out: marine conferences, distributors (defender.com)
Augment existing products or create own?
Research
Arduino for CoralHead
Protocol stacks on Arduino (IPv6)
