Well…… this has been an interesting conversation to say the least.
I waited a few days to respond to think about it. Not sure why this seems to have become a bit confrontational. And I apologize if this sounds like a rant. It is not meant to be.
I read the Sailnet forums religiously and have learned many things over the years from the wisdom of those with much more experience and knowledge than I.
Thank you everyone.
kd3cp ….. Actually, I did identify the unit. "Tripp Lite 3 amp power supply." It’s not like they make 20 different 3 amp power supplies.
The link Hartley gave in his first response takes you right to it. (thanks Hartley)
And thank you kd3cp for your valued opinion that this make of Power Supply is poorly made. I would have thought that the avionics shop that sold it to me to power up a $2K gps unit would have suggested something better built. …..Now I know. (I’m not being sarcastic)
For the record, I had not planned on leaving this unit powered on for more than an hour or two. I did not perceive it as a long term power source. I do not leave my extension cord lying out in the weather for long periods of time. So I routinely (when I leave the boat after working on a project that requires power) unplug the boat and bring the extension cord in. (yes call me anal ….. It‘s the way I do things) I tell you this so you know that there was no chance of leaving it powered up.
So, since kd3cp seems so passionate about how unwise it would be to use this unit, I will not use it.
Now, everyone just take a breath and try to trust me on why I take my batteries out of the boat for the off season. kd3cp and sailingdog…..there are
reasons why a person might want to take their batteries off their boat. It’s not about bad advice, it’s about what works best for me.
I must admit, I’m baffled at this turning into an argument about taking batteries off a boat (I feel like I’m being called stupid)!
My boat is a 27ft minimal electronics “kiss” system.
I have two group 24 batteries.
I bring the boat home every winter. Why? It can snow 4 or more feet of heavy wet stuff in one night. Then it could start to rain. (think of the snow as being like a sponge…..oh my!
) Every year someone loses a boat up here due to snow / rain load.
I did the “leave the boat in the water” thing a few years. Left the batteries on the boat with a trickle charger. But it’s hard to find responsible people to watch and shovel your boat when it is left in the water. (And you always wonder if when they shovel snow, do they have the same respect for your deck and bright work that you do?). Watching the batteries, shoveling snow, etc..... isn't cheap.
The closest harbor is 90 miles away from where I live. There is only one road to get to the harbor is and it goes through a two mile tunnel that restricts traffic hourly so that there is only a 15 minute window on the hour to drive through it. And it is completely closed from around midnight to early morning. Not exactly handy.
Can’t you understand why I might sleep more soundly in the winter knowing that my boat is high and dry in my back yard? Sure, some boats stay in the water up here. But the vast majority are taken out if there is anyway for them to do it. One disadvantage is that the boat no longer has the heat sink of the water. The boat gets a lot colder out of the water. Very big boats have no choice, I do ….. So now I take it out.
It can snow a lot in my back yard too….. And as I have said before, it can (though it hasn’t been as cold the last couple of winters) get more than 25- 35 degrees below zero F.
I have made a very strong braced tarp system that covers the boat and sheds most of the snow off.
We get wind storms in the winter. The wind might blow for days 30 to 40 with gusts to 70mph. Once close to 100. I lost shingles off of my roof last winter.
I have found that if you put enough tie downs on the tarp system it will survive the wind storms.
But this tarp system tied up and buttoned up on the ends restricts mid winter access to the boat. I could dig my way out there and untie the tarp and crawl in the boat but it’s not something I care to do any more than I have to.
The best place on my property to keep the boat is more than 6o feet away from the house so it takes a fairly long extension cord . There are the worries of having the extension cord get buried under the snow and possibly damaged or short out. I have moose that wander through my yard (even in the winter) I’d think all it would take is one hoof coming down on the extension cord and it would do the cord in. How about plowing or shoveling the snow?….. Another possible accident waiting to happen. This morning I found brown bear poop in my yard. Hmmm... let's not think about what gentle ben might do if he got tangle up in a cord lying out there.
Leaving a cord out is just not a good idea. I suppose I could get an electrician to put in buried cable and have a hard wired power plug put in out there. Sounds expensive to me.
Would it shock you to know that after I wrap my baby up in late October, I may not go back aboard again till March? Kind of a long time to hope that the trickle charger system is doing it’s thing. Having nothing on the boat that can freeze or short out gives me peace of mind.
Why not a solar charger? I’m at latitude 61.5 N. sailingdog, it may have been you that told me a year or two back that I’m not going to get much output from solar up here….. Especially in the winter with only 3-4 hrs of mid winter sun (not to mention if the solar unit got buried in snow or is blown away.)
Does anyone of you see why I have chosen not to leave the battery on the boat with a trickle charger on it ?
For me, it seems an easy choice to take 15 minutesand pop the batteries out of there and put them in my workshop.
They end up right next to my lawn tractor battery and my airplane battery. That way, I can personally monitor them from the ease and comfort of my heated shop. It’s not a matter of who gave me the advice to do this. It’s a matter of me knowing my circumstances. Sometimes you guys jump to assumptions a little too quickly. You are going to have to give me much more compelling evidence to change my mind about taking my batteries off my boat.
Taking my batteries off my boat has nothing to do with my original question.
My method is how I can get a battery to last many many seasons. Yeah, I know some guys that leave their battery on their boat up here….. These are some of the same guys that find out something happened a month or so back and the trickle charger stopped working. …….. Yep…..and they are buying new batteries every few years. (I’m talking about people up here…. Not in more moderate climes)
Another reason I like to do things the way I am doing it is that when I go to Hawaii for a month or more in the heart of winter, I don’t have to ask my house sitter to keep track of a battery on a boat.
My original question was posed just because I was thinking lazy….. And thought maybe this little power supply could have a use and spare me the few minutes to carry a battery back on board. Not a big deal…. But as has been pointed out…… electronically safer. (though moving batteries has it’s own risks eh?)
Now guys, don’t start in on me with a tirade on why would anybody want to live where I do…… pictures are available on request..
