Compass Lubber Line

[Stemar]

This is Jazzcat's compass, seen from the steering position.

Since she's facing SW, near enough, the lubber line is on the wrong side, but the light, under the lump at the back of the photo, but the forward part of the compass.

Is there a way to turn the things through 180 degrees so the lubber line indicates the correct bearing rather than being 180 deg out, while keeping the light where it is?

It's a small thing, but it would make steering to a compass bearing easier.

Is the globe free to rotate if you back off the mounting screws? The photos on the Plastimo site show a different orientation to yours so something must move.

Interesting when looking at photo ...

Assuming its not angle of camera to compass ... the Lubber line appears to be offset from the true centre., as well as the not indicating correct direction. This makes me think that the Lubber line has become loose ?
Second .. where are the usual other lines ? that are offset about 40 odd degrees each side ?

45 degrees either side and another pair at 90 degrees. See the picture.

I reckon the globe has been rotated. The lubber line should be furthest from you and against the numbers which appear the right way up.

Yep ... looking more closely I now see ...

Olympic 100 compass, deck-hugging | Plastimo, happy boating to you

Dealer photo shows lubber line offset from name plate ... which tells me rotation is possible of either compass or the ring separately .... to suit installation.

I had that on a previous boat many years ago after removing it to access some wiring. I remember discovering it just as I was about to screw it back into place. The fix was trivial, just a matter of inverting it, rotating and bringing it back into normal orientation. I cant' describe the action in greater detail as it was at least 30 years ago. You can just try it a couple of times and it will probably be correct at some point.

It will have been removed at some point and inverted by accident. Have you removed it recently or just noticed it for the first time after buying the boat?

Lubber lines are usually at the far side when the compass card looks like yours...



And they're at the near side when the card only has numbers on it's edges...



Perhaps as others have said, something it rotatable.

Interesting that both my photos show the Plastimo Olympic 115 yet they differ.

Edit. Corrected 'rose' to 'card'.

At least the OP has the 45 degree lubber lines which are perfect for when you're helming to one side..

 

[Martin_J]

Plastimo have so many different models...

With two sets of numbers you might get lubber lines front and back.

It's been like that since we bought the boat. I doubt the previous owners used it for several years as they didn't go far.

Ok, undo the screws and lift it out. You might need to disconnect the wire as it probably won't be very long.

Invert it as I described, turn it around and bring it back to right way up. You should persuade it to flip around after 1 or 2 tries. I seem to remember mine came with plastic screws. The stainless ones tend to make me think it has been taken out at some point.

Reminds me of the old trick we used to play with ships Lifeboat compasses in the brass binnacles. Exactly that ... rotate while inverting flips the outside glass / lubber ....
Used to be a game to see how long it took a cadet to fathom it out.

Try what Mistroma says in #13

If having difficulty
Roll it forwards until its upside down, then roll it sideways until it's upright again

Thanks everyone. I guessed it had to be possible, but wanted to have an idea what I was letting myself in for before I took everything apart. I'll give it a go this weekend.
