LED Lighting in the real world
18/03/10 07:49
We took the new boat out to anchor for the first time
a couple of nights ago. It is great to have the time
to be testing systems and sorting things out without
being in a big hurry. It is just early spring here
and we were the only people in a normally popular
anchorage in Chichester Harbour.
Also a chance to do some real world testing with the Imtra LED lighting. WOW. We already new the lights looked great from seeing them on at the boat show in January. But now I have been able to see just how little power they use. I did tests on most of the lights at anchor. I have a few interesting pix below. Of course it is difficult to get a representative feel with the camera but I did my best. The camera must be set to all manual operation so it doesn’t adjust for dimmer lighting.
This is the forward cabin lit by 4 big downlights in the ceiling plus the two reading lights at the head of the bed. Together the 6 lights draw just about 2.5 amps. To put that in perspective that would have been just over ONE 25watt halogen. These lights are so efficient we can just turn them on at anchor whenever we want. No worries about power. The saloon was the same story. The 6 big downlights light the saloon and galley with a nice warm bright light for just 2.5 amps. This compares to the 42 (similar space but lit with halogen lights) which used over 10 amps. So we have cut the power needed to run lighting by 75% or so!
Now here’s a real surprise. While I was checking I turned on the cute mood lights Northshore have installed in all sleeping cabins. These are not LEDs, but the rope lighting often used for decorating. This used more than the main lights! In fact the shot below is actually using almost double the shot above in power but producing almost no usable light. But it does look nice...
LED lighting really is here now. You can get very good looking light that will save a lot of power. And remember that saving power means you don’t need to generate and store it as well. So saving the power as we sat at anchor meant we didn’t have to replace that power the next morning. If you are planning an electrical budget you can stay with slightly smaller batteries.

The NEW BOAT!!!

Our new Southerly 49 is in the water! We have just come down to Itchenor in the south of England and are starting the process of moving aboard and getting her ready for the sailing season ahead.
Yesterday we took her out for her first sea trial and had an exciting sail. Wind was gusting over 25 knots and it is VERY cold! Spring is about 3-4 weeks behind schedule here in England.
Initial observations are that she is very quick. The extra waterline length over the 42 obviously gives us some extra speed but she is also a fair bit finer entry. She has just 6 inches more beam but 7 feet more length. She even has slightly lower freeboard which gives her a racy look. I’ll try to get some pictures of her from the dock today.
As soon as we left the dock we put up the mainsail and she was immediately running downwind at 8 knots!
Today its raining a bit so we’ll stay below and sort things out getting familiar with the new systems. This boat has an espar heater and its wonderful and warm! I made an anchor snubber by splicing an eye into a bit of 14mm line. Then just shackle the chainhook to the splice and I can give it a test today. So many little things to get her as ready as the 42 was!
