ABYC and NMEA
What are the ABYC and NMEA?
The American Boat and Yacht Council (ABYC) has been developing and updating the safety standards for boat-building and repair, including electrical systems, for more than 50 years. ABYC is actively involved with the International Organization for Standardization (ISO). They offer training and certification programs for marine technicians.
The National Marine Electronics Association (NMEA) has worked since 1957 to promote the integrity of the marine electronics industry by developing industry standards and furthering the skills and qualifications of technicians through education, communication, training, and certification.
Our membership in and certifications by these two organizations indicate to our clients that we are dedicated to best practices and that we incorporate the newest technical advances into our work.
It’s better to have the work done right and spend your money well the first time,
says Michael. I feel much safer now when I’m on the boat, and safety is the first priority. I don't have to worry about turning switches on and off. I can just turn the key and enjoy the boat.

Q: 
I can't seem to decide on a 12V or a 24V battery for my bow thruster install. I don't understand why I'd choose one over the other - I know it's the same idea as for a windlass but why choose 24V? I know current draw is half in series and I want to the load on the batteries to be low, but I need two batteries anyway to make 24V. So if I use two batteries for 12V and put them in parallel, I'll get double the capacity. The thrust is the same and some people were saying a 24V motor is smaller but the overall dimensions are the exact same. What should I do?
