Woww, that's fantastic all. Ask and the knowledge flows, Thanks all.
LED into the nav light which seems to be the big sucker. Currently working on 10 hrs per day - 25W in 12V comes to 20Ahrs a day (thanks for that bit hellosailor). Being a tad generous with the time on as it won't be getting dark till 9pm but trying to leave some safety
To get a 25 watt equivalent in LED does anyone have any idea how that works and possible consumption? We must have '25 watts' for the rules and as we will be skirting oil
fields and the like I don't want to get run down by a tired oil
tanker driver, I'm way to pretty to die just yet
Apart from that we have a small amount by VHF when out of range for the handheld. A simdgen for autopilot
for the odd break, it's a 2 handed race. inside lights at night. A splash of stereo which is a big sucker but then it is a bit silly sized. Otherwise we are pretty stripped down for the hard racing season. Come October I'll load the seemingly 4 tonnes of cruising gear
The workout, if done correctly (please correct me if I'm wrong) we get to mid 20's maybe 30 Amp hours daily if pushed and stereo is very heavily limited. I'm not sure how you work this battery capacity/reserve thing so are erring a little on the cautious side just in case. Don't want to get race officials pinging me for 'stealth sailing' at night.
I worked it out like this -
Thingy X is 25 watts.
Devide 25 by 12V to get 2.08 Amps. .
Thingy X on for 10 hours a day so 10 x 2.08 is 20.8 Ahrs used.
Correct or cock-up?
I am assuming I'll never get to use all 120Ahrs in a 120 Ahr battery from what I've read here. Any idea what one could get out of a 120Ahr for short duration but big drain situations wityhout completely killing it? meaning, if it all goes horribly bad how many Amp hours could I reasonably expect to get assuming it was full and we couldn't charge anymore. It is only a few months old and gets some low level in and out flow each week currently.
Who said 'Equalise' the battery, what does that mean? Sounds like a good thing even if I don't know what it means.
All other lights have gone to LED already which saved massive. Those new lights use next to nothing, nice.
GPS's are heldheld and VHF handheld as well as wired in one. The handhelds will be on when required and off otherwise. They want us to make lots of calls so we don't disappear, how caring.
Didn't realise solar panels
whack out that sort of numbers, nice. Will investigate that one.
Prop off the outboard, that's damn cunning. Will trial that one to suss speed lose. Might be surprisingly small.
As Hellosailor (done some racing I see) said drag is a nasty and a big no no. Saying that I do like the towing concept
otherwise and are going to suss that for the not speed critical times. Sounds nice and simple.
2000 was/is the current
plan. Damn nice units with 55Amp output if we are talking that Aussie made one. Just though I'd avail myself of the learned forumites to see if they knew better ideas. Guess what? you do.
Now don't go away all. I'm going to digest this lot and will return will questions, probably silly but that's just me. This Elictrickery stuff is all a bit gobbledgook to me. Not so much this evening as it was this morning though.
Thanks again, you're all wonderful and I'm feeling the Cruisers Forum love
