1896.0. "Compass Woes" by AKOCOA::HAMEL_WHITE (Dreams For Sail) Wed Jul 15 1992 09:49

I bought a 1978 ODAY 22 in the spring.   She is in beautiful condition, and 
I have enjoyed sailing her despite the foul weather.    However, I recently 
went out to go sailing and found that the compass had leaked its fluid down 
through the plastic housing in which it resides on the outside of the cabin. 

It was a grey day, and I could not tell whether the plastic housing for the
compass was also cracked.    At any rate, the compass is useless, sitting 
rather lopsided inside its clear plastic bubble housing.


I am wondering whether (assuming the housing is alright,) I can just buy another 
compass, unscrew the housing from the cabin wall and insert it.    Has anyone
had this problem? 



thanks,
Carol

    Fixing your compass should be relatively easy !!  If it is a lighted 
    compass be careful when removing it from the bulkhead so as not to
    damage any wires.  (Be aware that wires bringing power to the compass
    light are often buried under teak trim, or other decorative woodwork on
    the inside of your bulkhead.)  You will need some type of sealant to
    ensure a good watertight seal between your new compass and the bulkhead.  
    Other than these two points, changing a compass should be a painless 
    process.
    
    FYI - I purchased a new boat this spring.  In testing lights, etc.
    before launching I was really frustrated that the compass light didn't
    work.  (There were wires going into it from under teak trim inside the
    cabin.  A continuity check revealed the circuit was good....)  Taking the 
    compass apart, it was soon discovered that the light bulb had been 
    installed upside down by the manufacturer !!  Having discovered the 
    problem, it took a few more minutes of patience uprighting an extremely 
    small light bulb, application of waterproof caulk, a brief period of 
    chasing some runaway screws, and the re-installation was complete.  The 
    compass and its light work just fine.
    
    Good luck with your project.

re .0:

The plastic dome in which the compass card lives may have developed a 
leak due to degradation of the dome by sunlight. If you can see crazing 
of dome, this is likely the answer.

Good compasses can be repaired, but it may not worth the expense for an
inexpensive compass. The dome and the outer housing are not sold
separately -- you'll need a complete new compass. Ritchie makes good
compasses. 

When you install the compass, use silicone sealant. Don't use BoatLife, 
3M 5200, Sikaflex, etc.

    A relatively recent Practical Sailor did a compass comparison, you may
    wish to check out.  If I can find it, I'd be happy to share the info.

    Some compasses (Ritchie) use a LED for the light source, it is polarity
    sensitive.  If hooked up backwards you have NO light.  I went round and
    round with that for about a half hour before figuring it out.

1896.6Refill itCALS::THACKERAYWed Jul 29 1992 14:365
    If your compass is in good condition, and the leak is something simple
    like a loose filling bung screw, then refill it! Mineral oil from a
    supermarket should do the job.

Ray, that is such an interesting idea.    I will see if your solution can 
work for me. 


Thanks everyone, for the help.  Will let you know how I make out, if I 
ever get around to fixing this thing!

1896.8Priority, CompassRDVAX::LAZGINThu Aug 13 1992 14:037
    Yes Carol, you should fix it, AND carry a hand held compass as a
    back-up.  This should be close to the 'top' of your priority list.
    
    Fog can and does move in quickly over the water.  You've got to
    have a reliable compass.
