Re: Viewing in the cockpit

Whats wrong with just using a clear plastic box with a lid, and wrapping a few rolls of black tape around it, and cauk the wire/cabling hole in the back?

Not waterproof but I really only want this viewable from the helm in close quarters, ICW, channels, etc where the chance of waves in the cockpit is nil. Off shore in deep water I don't really see the need for a chart in the cockpit so can keep it below and dry.

Highly recommended for anyone rigging a DIY nav system. If you really wanted to keep it in the cockpit full time it wouldn't be too hard to rig a waterproof cover for the screen.

Takes a standard VGA output from a laptop or video card so a standard monitor extension cord works fine. It does want a 19V power supply but I got it to work on my boat 12V supply. Just wouldn't work at the brightest screen setting on 12V but I didn't really need that anyway.

Re: Viewing in the cockpit

Skipmac,
Any idea of current draw on the VDL02?

Have not measured it so all I can tell you is the rating on the back. First, I was wrong about the voltage, not 19V but rated at 15.6V 3.85 amps.

That I am sure is a max power, worst case scenario kind of rating at max brightness. There is a button on the front that lets you adjust the screen brightness and the power draw will go up dramatically with the brightness. When I get minute I will hook it up to my Fluke and test the draw but would be willing to bet under 2 amps at a medium setting.

Because that's not approved by the IEMEA


(International Expensive Marine Equipment Association)

Also, some electronics will get a little warm in a closed box.

BUT!!! If you poke holes in the box to let air in for cooling then water can also come in to kill the screen (or whatever is in the box). That's why waterproof stuff costs more.

Re: Viewing in the cockpit

I ran a VDL02 thru a meter a while back and this is what I found for draw:

There were 10 different power levels that could be seen with the meter, not so easy to see by brightness.

Full Bright -47.5 watts
9 - 42.5 watts
8 - 37.5 watts
7 - 32.5 watts
6 - 26.3 watts
5 - 22.5 watts
4 - 19.3 watts
3 - 16.2 watts
2 - 13.3 watts
1 - 7.2 watts
0 - 5.6 watts

Level 1 would be just fine for night sailing and full brightness is only required in direct sunlight. So skipmac is right on with the 2 amps at a medium setting.

Some things are best saved for the V-berth.

Not being one to wish to recreate a "Star Trek bridgedeck" experience while sailing, I'm pretty sure I could punch the "off" button 99% of the time on the sailing deck, and either make the "round trip" below (as most of the time out of harbour is under vane or AP anyway) to check progress (and where that monitor would also be dialled to zero when not actively needed).

So this is not a draw problem (aside for power lead sizing), but a discipline problem. If I need a nav monitor at high noon on the Equator on the Equinox, I don't care if it's drawing a hair-dryer's worth of watts. It's only needing to be on for a couple of minutes, unless I'm picking through a dog-legged bunch of coral heads, in which case I'm watching the sounder and taking my cues from the missus up the mast with polarized glasses and a bunch of well-tested hand signals. It's like balancing off watermaker draw vs. output: make water while motoring and it doesn't matter so much if you collect rainwater for washing or lack, well, a motor.

Yeah, I'm exhibiting the Scottish gene and I am also the guy who roams house and boat switching stuff off when people have left the room.

Thank you very much for that. I was getting ready to drag out the meter and start rigging wires to a battery in the garage to do this. Love it when someone else has already done the tedious parts for me.

Exactly. Why do you need a live cockpit display offshore when all you see on the screen is a little boat icon surrounded by blue?

I would use the cockpit monitor in the ICW or harbors when encountering lots of twists and turns in the channel or coastal at night in areas where they have these big, unlit buoys for miles offshore.

AIS perhaps? Or the radar overlay?
