Boat: Chrysler 26, swing keel
and doing a lot of (New custom made roller, installed an anchorman , New 25# with 5/16" chain and new braided nylon etc...) I may have read just about every thread in many of the here and have learned a lot!

Thank you to all!

I eventually will remove all and start from scratch as I don't like how the previous owner had it set up, but we're leaving in July to spend a month cruising the and just had to change some of it before we leave (Added , completely rewired our 120v system (double pole breaker, GFCIs etc.)

Just finished refitting our 12v and 120v systems on our C26, tested them out and everything works great:

Two G27 (I'll eventually change the house to trojans)
On board 2-bank 8A Pro-mariner

I'm also adding two 100watt with a controller and I have a question (I know a LOT, but I also "know" that when I "think" I know a lot, the best approach is to do so as if I know nothing!

Here's my question:
While in a marina using and our Pro-mariner , can I leave our connected?

My guess is, that the charger will recognize that additional is taking place and will limit the amount of amps it will send to the (I'm only our house because we plan to spend a lot of time on the hook and buoys.) I'm also thinking that the Pro-mariner will recognize the same and will limit the number of amps it sends to either battery.

Am I missing anything?

This comes from melting down our battery after connecting wires what the previous owner told me were positive... They turned out to be negative! and battery selector switch with new, fused the "unknown" polarity wires and used my volt meter for confirmation... Still have of melting wires and smoke in my ... As an ex-firefighter, this is not a good image to be carrying around in my ... But does add to my respect of what "electrickery" can do! LOL!

Thank you!

and our Pro-mariner charger, can I leave our solar connected?

My guess is, that the solar charger will recognize that additional charging is taking place and will limit the amount of amps it will send to the battery (I'm only solar charging our house battery because we plan to spend a lot of time on the hook and buoys.) I'm also thinking that the Pro-mariner will recognize the same and will limit the number of amps it sends to either battery.

is supplied by AA Nicad cells in converted "Harbor freight" ... These are charged via a smaller (1A) solar charger with it's own solar controller. Many of our "accessories" (Cameras etc) are powered with the same AA cells. We have a 640 with Vision blue chips for the area including , LOTS of paper for US and , a hummingbird finder (visual (bottom condition), and back up for our installed digital . We also have meter and log, speed and direction...

As an ex firefighter, I'm always paranoid about fires! (We're carrying 5 extinguishers! LOL!) I was shocked (no pun intended), when I first hooked up my batteries to see my cables melting and smoke everywhere! Should have followed my gun etiquette: Ask if it's loaded and then make them open it up to hand it to you with the action open so you can see for yourself... Should not have guessed or assumed the polarity of the questionable wires! experience but are now only interested in coastal/Gunk-holing which is why we now have a . Future plans include , and the ...

Totally going bonkers on items and getting everything "perfect" (Ha!) My wife keeps reminding me that I sailed solo up there in a little 21 with only a handheld and handheld using paper and a small danforth wanna-be (No , No etc...) Old back when was popular (And I was a lot younger!). LOL!

Thanks again!

in harmony with the other charging systems on board, be it from your , shore battery charger or other charging devices. The controller will limit the charge based on the voltage exceeds that it's terminals.

. The charger sits at rest and I don't have to pay for shore unless I use the A/C.

. You have good reason to be concerned about boat fires. I have seen two and when they go they go quickly. Interestingly, according to some figures, over half of all boat fires are proven to be electrical in origin. The figure is likely much higher but they cannot determine a cause in a large number of them. Of the ones that the can determine the origin, some 55% of the electrical fires originate in the shore power system.

There are a number of reasons for this. A major issue is that too often forms on the contacts and receptacles. As I'm sure you know, equals heat, which equals bad things. Another interesting thing is that the manufacturers recommend that you not draw more than 80% of the rated Amps. If you have a 30 amp cable, you should not draw more than 24 Amps on a steady basis. Many who really know electrical systems say don't draw more than 70% or 21 Amps.

The reason for so much trouble with shore power is the . It was designed in 1938 for building use, not for use. It was state of the art then but is seriously outdated now. The three prongs provide ONLY some 6 square mm or surface area! When you add this to corrosion, movement, moisture, and lots of juice, it's not hard to see why they can burn.

A much better solution is the smart . This provides a secure locking in place of the plug and most importantly, it has some 700 square mm of surface area.


Full disclosure: I do NOT sell these. I just like them.

N.B. Plenty of people use the traditional shore power cables and have no issues. I myself had it connected for several years and had no issues. I also constantly unplugged it as I was sailing all the time. Once I learned about it, I stopped leaving it plugged in all the time. I only use it now for specific needs, such as doing work on the boat that requires more power than I can generate myself. I am going to change the plug after I finish a few other projects. Since I don't use shore power very much I am not in a rush. If I needed it regularly, I'd change it out ASAP. They're fairly comparable in to traditional plugs and cords. I know Amazon has them.

Good luck with your .

if needed.

We would "every once in a while" visit a marina (Trash, out, , , , sight seeing etc.). I figured our shore power charger would make up for what our solar power doesn't provide. Probably 24 to 48 hour stays with shore power. And then leave to go back on the hook for a week or so with our batteries topped off.

I was just concerned about leaving the solar connected while plugging in our 120v charger.

As for Sea of Cortez? Our absolute HAPPY PLACE!!! Been going down (when I lived in Los Angeles), since the road opened up (dirt at that time), in 1973! At LEAST 5 times per year towing smaller sailboat and boat... =D

Thanks again!

between islands, will be used for 3-4 hours.

Calculated boat's amperage usage at 17A/day with 6hours cruising. 200 watts @ 10A (max... LOL!) "should fill us back up in a couple of hours of good daylight (Days are also longer up there when we'll be there.)

Stereo (included in my amp hour calculations), will be the biggest draw, but we both play and plan to play a lot!

So shore power will be used to supplement our solar. I'll keep the starter battery for starting only and if that fails, it's a newer 9.9 start WITH hand start which works well.

space in your boat - looks very comfortable for cruising. When you redo the electrics think about moving up to the 12A charger as a minimum. It isn't that costly. For stereo, I am using a rechargeable Sony Bluetooth speaker box playing off my phone/iPad.

much larger. We both have experience, but when I moved from Los Angeles to (She was already living here), I thought my sailing days were over. Took a 21 to the and then it dawned on me: I could use a trailerable sailboat to get to the cruising grounds I was interested in exploring... (We both "Gunkholers" at heart.) I needed to find a boat that was much closer to blue capable with larger "liveable" boat features.

Took me a year to discover that back in the day, Chrysler (of all companies), produced the C26 (Hershoff design). Slept 6, 6' standing , wrap around , private head... Swing rests below the waterline in a sort of shoal long outer that was also weighted... Very stable! When I first shared this with my sailing buddies in Marina del Rey, they all replied: "Oh Richard... What have you done!?!?! . , we may just sell it all, move to the (ICW, , , Caribbean), and buy a larger boat... I still want to re-do the electrical on this one for safety's sake and we're still planning to take this one to the Sea of Cortez.

OK... back to boat work... Installing water with fills and a whole bunch more. Raising the tomorrow and going over all our .

Best,
Richard
