Shore Power Cord

My boat is 5 feet from power supply and I have 30 feet of extra cord on the deck. Should I put unused cords in a container, of some sort, rather than just on the deck in the weather. Would this prolong the life of the cord?

Personally I would make a short cable just for this application.
I'm not sure if you can buy shorter than 15ft. But they are available if your not comfortable making one.

Unless you plan on shortening the cord at a later date, boxing the extra cord doesn't protect the exposed portion.

There are UV covers available for power cords. Expensive and more cost effective for 50 amp cords.

I'd make up a short cord and use that at your home dock, leave it installed on the dock when you travel, only use the longer cord for traveling. Makes leaving at returning much faster.

Yes, our retro-fit Glendinning Cablemaster is a wonderful thing.

Absolutely. Best value for boat bucks.

Good point.

You can buy a cover for the entire cord or you could make a short cord. Only if you are sure you can do it correctly. It might cost as much for the parts as an entire manufactured 25 ' cord though.

You might be able to find someone to give you an old cord with one end damaged or sell it cheap. Then, you would only have to buy the other end.

I have one of these on my boat, they work well for cord storage. You wouldn't think a 50' 30 amp cord would fit in it but it does, not the end plugs.
In Kartracer's application the ends would still be exposed, maybe a fabric cover for them.

I have about 15 ft of extra, which I wrap around the dock box. Every 6 months, I pull it off, and wipe it down with Colinite, or 303 UV spray to keep it from degrading, and building up the black stickies. It still turns color, but the outer jacket is still in good condition.

Hang the cord coil on the power pole and forget that it's 30' long. Suppress your anal retentive nature and be happy.
Buying a shorter cord or making one will cost you the same or more than a 30' standard power cord because they mass produce them.
In a perfect world a cord that was just the perfect length would be great. But this is boating. Worry about your boat zincs, the growth on the bottom and how your going to keep your bow thruster clean.

Every time we're aboard, we learn something new. Last weekend, we learned that it's easier and less exciting to leave the engines in neutral and walk the boat back out of the slip; we both handle docklines and hang them on pilings as we pass. This weekend, we learned that the shore power cord is a very competent dock line...

Ah yes, but you're forgetting that coiling the cord while in use creates inductance (similar to resistance) which will produce heat in the cord and reduce the available voltage at the boat.

Perhaps- but coiled cable in a cablemaster doesn't seem to be much of a problem...

The Glendenning device is the way to go.
If you don't want to spend the big bucks, it is very easy to make a cord of any length you want. The terminals in the connectors are all color coded. Even someone dumb enough to own a boat can do it.

Am I on camera?
Is this getting Punked?

Seriously I have never experienced warm cords
Or voltage drop due to coiled cords.
So is this a problem in theory or for real??

Oh...don't worry, we have been repeatedly reminded pro electricians are required because boaters can be dumb enough not to follow color codes.
