Underwater lights

[Bojangles]

LOL, I had to google that one.
And I found this woodenboat forum thread, which maybe you and LS might find interesting.
What's next, are you going to suggest "Tarted up frozen snot" as the most accurate description for the Delaware version of SR?
And maybe also for any other MoBo with u/w lights....?

PS: as much as I love displacement MoBos, I can't disagree with you on the 4 storey monster.
And I guess you weren't aware of her top floor arrangement - see below!

Oh yes MapisM, I like it, why not have a new thread, "hot tubs on boats" (with or without underwater mood lighting) I could just about write all the sceptics posts for them..

with or without underwater mood lighting

LOL, you could as well call it "Spectro-Chrome Therapy" and you'll find people arguing that it can prevent cancer!
I still prefer to jump in the sea when I want to take a bath, but what do I know...?

 

[longjohnsilver]

Oh, don't worry, we can't complain after all - see below, just in case my avatar is not clear enough.
In fact, I did say that I moved elsewhere in a few cases.
The whole point, as I understood it, is whether anyone would rather live with with the sh!t or with the u/w lights.
And fwiw, I'd rather move elsewhere for the first than for the latter, but each to their own...

That's a disgrace M, your starboard prop needs a damn good scrub!

 

[Searush]

And to think how hard I try to kep the water outside my boat!

BTW, where does the water come from for that tub? I doubt it would carry enough fresh water in tanks to fill it a couple of times, so I guess it comes from the sea - so why the flip would you bother? Just imagine the effect of all that weight up there if you had to move cos the anchor dragged?

I see where you come from LJS, but nope, those spots are actually just missing bits of a/f paint.
I've always had excellent results with the antifoul of u/w gear, contrarily to the experiences of most other med boaters.
Which is probably explained by the very different rotation speed and prop load of displacement vs. planing boats.
But the stbd prop has developed its own attitude... After just a few weeks from the launch, it begins to loose some small a/f small spots, and from that point onward it tends to get worse, but just a little.
The above pic was taken at the end of Aug, and the boat was launched at the beginning of May, just to give an idea.
I can't understand if that is due to a) the boat position it her berth (the stbd side is more exposed to the sun), or b) a slightly different prop load while cruising (I always keep the engines in sync, but since they aren't electronically controlled I can't check if at any given RPM the load is aligned, so the stbd prop migt have a slightly higher pitch, working a bit more as a result), or c) any other possible reason I'm missing... (ideas welcome!).
Anyway, next year I'll have both props scrubbed to bare metal, maybe it's simply the primer which was done on friday afternoon on stbd prop!
That said, barnacles don't seem to like small patches of non-antifouled props, so at the end of the day also on stbd prop the a/f does its job nicely, in spite of the not so good aesthetic result...
Below another pic to better show what I mean.

I wouldn't bet that the tub is filled with sea water, though.
Aside from massive water tanks, surely a Nordhavn 68' must have also rather big watermaker(s).
And even with sea water, I reckon that you need the tub anyway, if you want a whirlpool massage. Arguably, even more pleasant than u/w lights...?
Re. weight, well, I don't think a few hundreds kg will make a helluva difference. Not on a 4 storey monster, anyway...

Ha! Now I can see better it's actually the shaft which needs cleaning, shouldn't have risen to the bait M..................
I also put antifoul on my props last May which seemed to be doing an Ok job when I last looked in July. What they're like now I have no idea but will no doubt soon find out.

... and so you can heat it of course, as Nordhavn's often dont restrict themselves to the warm waters of the med or carribean. I guess it might be quite nice cruising through the calm waters of the Norwegian fjords, admiring the snow topped mountains from the comfort of your 37 deg hot tub?

As the owner of the boat being discussed, I couldn't resist posting this picture:

This was taken near Glacier Bay in Alaska. A hot tub on a boat may be a silly idea, but, not when you are sitting in it. This particular hot tub has also crossed the Bering Sea, and is currently in Turkey.

The boat (Sans Souci) has twin 80gph watermakers, and the tub takes about 250 gallons of water. As someone said, it is a lot of weight up high on the boat, and I always empty it before moving the boat.

Yes, Lumishore have supplied "Ice-Class" lights to 1 Nordhavn (hopefully more to come!) . An excellent excuse to share some images from a Lumishore customer who has become a friend and earns his living as an Icebreaker captain ( and he is only 40 yo!).

Here is one of his recent 'Homes'

His other boat, with some very 'relaxed' Tarpon in a Miami marina

Like MapisM (and most of us here), George hates 'Sea Turd' pollution. He loves his Lumishore underwater lights ... and, as he wrote to us -- our lights enabling him to photograph this in a 'Miami location' whilst diving at night blew his mind. A first for him apparently:

No pics mate, something has gone OceanLed...


now all loverly and Lumishore ;-)

No pics mate,

Hopefully now OK ... didnt realise dropbox didnt work !

Well done EME, some have questioned the point of having these lights, how nice to see wonderful creatures that otherwise would have went by out of sight.

Bojangles Thanks. There always seem to be lovers & haters, all Lumishore can do is do it better than anyone else.Not really borne out by this and other threads, but lovers include many 'sailors' - probably says more about the contributors than any motor v sail debate

Anyway here are a couple more 'of George's amateur photos reflecting his love of the marine environment. The first courtesy of Lumishore:

and the second from his working life that he sent me and he titled "Goldilocks"

Whilst I'd agree with SeaRush on the large tub of water eek, I'm certainly looking to add underwater lights as part of my ongoing rebuild. I don't quite get the objections and EME's last posts illustrate my main interest and that is improving underwater visibility. Being Asthmatic, I'd never be able to go diving so this will be the next best thing for me! I'm also thinking about an underwater webcam...

In the UK I don't think that you would see very much very often

I can see the appeal in warm clear seas but for obvious reasons I would prefer to have less holes in my hull.

I think you might be quite surprised. I've taken pictures locally where you can see clearly down to 2M or more in daylight - at night that would be even more with some added light! Perhaps the water is clearer down here in the SW?

As evidenced above by Phil you can. Just need brighter lights although I personally prefer Green/Blue/Cyan/Magenta etc mixes in coloured waters.

Lumishore do have 'no-holes' lights although I guess a canoe might be the best way to satisfy your preference

OK, UK is a bit broad. I have spent some time in SW and have seen some clear water off rocky shores.

I would sooner fit furry dice to my rear view mirror than fit under water lighting and the former definitely won't happen!
