Can anybody recommend a good introduction/overview of electric systems on a boat for somebody that knows nothing about it? How it all works? How you know how much generating/battery capacity you need?

Thanks,

Donnie

Donnie, this is a really important question and what this website claims to be all about. We have a category devoted to "resources" and a page for "technical resources" but it is lacking in good information at the moment, I have to admit. It is near the top of my to do list to add some good resources here and really make Electric Seas a central source for general information about electric systems on boats. Please check back here in the next few weeks and you might find what you're looking for here on this website. There is a lot of good information out there but it seems to be scattered and I want to do a better job of collecting it all here. In the meantime, a lot of our members have collected some good information and have good reading lists, like Capt Mike has posted here.

A basic primer I used in building my all electric dory was "Electric Boats: The Handbook of Clean, Quiet Boating".  It's an older book but goes into a lot of detail on how to calculate power needs and battery size. It mostly discusses small electric boats but the information is easy to transfer to larger boats like I did with my 26' dory.  

 It doesn't, however,  go into any details on how to integrate it into larger mechanical systems such as diesel engines etc.  It also doesn't discuss how to integrate it with AC systems in larger boats, nor does it discuss the newer Lithium Iron phosphate batteries that could be used.  The lithium technology looks exciting but it is still  about 3 times as expensive and the standard lead-acid.  I keep hoping the prices come down so I can put into my electric pick-up truck.  I will keep the lead acids in the boat however because they provide my ballast as well.

 

You can find used copies on Amazon at a reasonable price.  I believe it is out of print so new copies are expensive.

Another good source of information on batteries in general, but only batteries, is the "battery university" web site (www.batteryuniversity.com )by the president of a company called Cadex.  You could print off their information pages and compile them into a notebook.

New boat taking shape

Taking on another big project and just looking to see if anyone might have any feed back4 years ago I restored a 33foot Morgan O/I and repowered  with a Thunder Struck 10kw drive and a 310ah FLA battery bank I am very happy with this boat and lived aboard for 3 yearsBottom line I met a girl that likes living aboard as much I do so I bought a 43 foot Gulf Star trawler no mistake about it. Its a huge project but it is moving alongIt is powered by Perkins 6-354s my plan is to sell them and repower…See More

Electric power for a 16 ft runabout

In the mid 1990's Phil Bolger, a naval architect from Gloucester Massachusetts, designed an electric runabout for the home builder called the Lily.  Recently there has been some interest in upgrading the design of the propulsion system and batteries to make better use of current technologies.  Here are my suggestions for upgrading the original system in Lily. The MotorsIn 1995 Lily was set up with a 24 V trolling motor, and I consider trolling motors to still be the most cost effective option…See More

Mini BMS

I'm closing in on making the switch to lithium. I am using a Mini BMS for the battery management and having trouble getting the AC relay for the charger to reset. The "key" terminal on the head board is connected to the switch but it does not reset the relay when cycled on and off. If I physically disconnect and reconnect the 12 volt supply to the board the AC relay resets. Does anyone know what the "key" terminal on the head board wants to see?

Electric sailboat endurance estimates and experience

We talk a lot about range in miles at various speeds, but I think for cruising sailboats the real question is how long can you go without needing to recharge. This includes house loads and motoring.When we had Snow Lily (Tartan 34C) repowered my goal was to get 5 to 7 days cruising without needing any sort of recharge. I was cautioned to go with diesel as range would be a problem, but I really think in terms of sailing and not motoring. The motor is only for in and out of the tight marina, on…See More

Post your boat speed !!!

I'd like to try to get a handle on boat speeds.So please:  post your boat details and speeds!  I'll get the ball rolling....- Defintion of "takeoff weight":  just like aircraft:  entire weight of craft + batteries + humans + everything.  If you don't know, take an educated guess.- conversions fyi:        1km/hr = 1.6mph        1km/hr = 1.852knots- HOW I MEASURE SPEED:   I find GPS's generally suck at reading low speeds.  What I do is take two known points (the corner of my dock, and the corner…See More
