Re: Electrical 101

You may even be able to pick up a charger on Craigslist. If you're in a saltwater area, I'd avoid the stuff from Harbor Freight or some of the other, inexpensive chargers. Get a good quality marine charger, even if it is used.

Re: Electrical 101

I am in fresh water.

Will probably get a 2-bank marine charger. And as suggested, see how things go in the first season and assess needs from there.

Re: Electrical 101

Hey,

IMHO, you need to decide what your plan is BEFORE you do anything.

If you will use the boat by going there in the morning, motoring out of the slip, raising the sails, sailing for a few hours, then lowering the sails and motoring home, you don't need to do anything.

If you plan on spending time aboard in the slip, running a fridge, TV, Computer, and sound system, you will need to some changes.

If you plan on sailing off for a few days or longer, spending nights at anchor, with some electronics to run, you will need some different gear.

Figure out what you want to do with the boat, and THEN decide on what to do.

Barry

Re: Electrical 101

I suggest that the GI is more important than the charger. Also, I would not consider a used charger. YMMV

Re: Electrical 101

Hey Barry. It will be option 1 and 2 in the first season. What do you suggest for that?

Option 3 in the following seasons.

Re: Electrical 101

Anybody else using a GI? Is that standard issue?

Re: Electrical 101

Congrats on new boat Keja...Suggest you determine condition of
batteries 1st and foremost and then how to maintain and monitor them. Check out "load testing" and "specific gravity" both easy but checking with a multimeter will be a good start.
Monitor battery voltage after day sailing a few times.
Did you said you have shore power... follow wires...thinking just might be attached to a charger.
As you indicated you will be day sailing at first, if your batteries are in good shape you may be good as is.
Suggest you take some time and practice approaching dock under sail in any case.
for what its worth...I keep my 30 fter with one bank for start and house, constisting of 2 group 27 batteries, on a mooring (have charger I dont use) Use modest solar panel and keep a batt booster on board which I had to use only once in 20 yrs.
I buy batteries every 7-8 years in any case. (usually still good)
Useage is moderate with no refrig.
and never have any electrolisis (spell?) problems not connected to shore power.
Spend approx. 20-25 days on anchor in a good year.
Hope this helps,
Hugo

Re: Electrical 101

Hey,

Like Hugo, my boat is on a mooring. I don't use solar or any other power. I run my engine 5-10 minutes to get out of the harbor and then another 5-10 minutes to get back on the mooring. For day sails where all I use is the chartplotter and instruments, and listen to VHF, the short engine use is enough to keep the batteries charged.

I get 5+ years of life from a set of Costco marine deep cycle batteries.

If I go away on a 3-4 day cruise, I may stay in a marina for 1 or 2 nights. The other nights will be at anchor or on a mooring. When I stay in a marina I might connect to shore power, or maybe not. If I don't , running the engine for an hour or so is enough to keep the batteries up. My electric use is pretty minor - no refrigeration, microwave, blenders, etc. I have a few LED or CFL lights, charge phones and computer, run a radio, etc.

So, assuming you don't have a battery charger but do have shore power, I would sail the boat as is for the first year. Make sure you have a decent meter so you can check battery voltage on a regular basis. As long as the volts don't show a steady decrease you will be fine. If you do see the voltage decreasing on the house bank you will need to run the engine longer to charge them up.

Good luck,
Barry
