So I bought this BN-202 compass. Obvoiusly it has to be mounted horizontaly. So it fits like [url="http://home.wmis.net/~dhapp/compass/compass.jpg"]this?[/url] It can't possibly go like this but I can't figure out what I'm doing wrong.
There is not a sailboat in the world that this compass would fit like this. Do I really need a 6" thick teak block to mount this compass? What am I doing wrong????
Sorry for the rant but I am so pissed about this.

I went looking for installation instructions but found this [url="http://www.discountweather.com/nlb.html"]”bulkhead leveling mount”. [/url]
The caption reads “If you are mounting the BN-202 in a bulkhead that is not vertical you will need to shim it. Precut with a 7 degree angle to match the most common bulkhead angle, this solid teak block was designed just for that purpose.”
Sorry.

Send it back and buy a

We have a plastimo like that, it mounts fine on the angle....if its a disc floating in fluid, it shouldn't make a difference if it isn't flush......

Should it?

I agree with Duane it should work anyway.
An easy test is to just hold it at the angle of the bulkhead and spin 360. If it spins free you’re in business, if not. either buy the shim or trade it in.
Check it before you drill the hole.

The disc bottoms out at the angle of our bulkhead. I would need a pile of those 7 deg angle teak blocks. In the photo, my wife is holding the compass level and you can see there is a 4" gap at the top of the compass. This compass doesn't even fit a vertical bulkhead. For this compass to bolt strait away on a bulkhead, the bulkhead would have to slope aft at the top about 15 deg. Where would this comapss ever be used?
If I install it through the hole from the inside it works perfect. Since I can't see through walls, this piece of junk will have to go. Suunto it is.
Thanks for the reply guys,
Dan

Dan,

That photo of the compass being held up to your bulkhead just ain't right. Either the compass is being help upside down, or something's assembled upside down, or that compass was designed for some other application entirely. If you like the compass, I suggest you contact the manufacturer, and describe the situation. I'm sure they'll either make it right, or convice you not to buy or recommend their products.

In my 1979 C-25, I installed a Plastimo Contest 101 bulkhead compass. It fits and works just fine. After almost 10 years, I'm still satisfied with it. It's one of the those which can be read from either side (cockpit or cabin), a feature which I find entertaining, if not entirely useful.

Dan,

I had a Ritchie BN 202 on my boat for years. It will not function without the leveling block. You must also cut a larger bevel in the block. Ritchie makes a great compass but not for our sloped coach roof. The block looks nice when oiled but sticks out a little much. After 15 years of climbing around it, one of my crew stepped on it and damaged the compass. I bought the Plastimo from CD. It works great without the leveling block and had only a 2 degree error after mounting. I haven't had to touch it since. I know this isn't what you want to here but......save yourself a lot of frustration,return the BN 202 and get the Plastimo.

My first thought when seeing the picture was: "upside down." As Leon said, perhaps the compass is incorrectly installed in the mounting frame?

Thats a compass for a pedestal, not a bulkhead.

I'm one of those minority C-25 guys with wheel steering and I have to agree that unit looks like a pedestal mount compass. I think it's almost identical to the one that's built into my Edson wheel pedestal.

Go for the Plastimo! :)

Somewhere, the instructions should specify the maximum angle (like 25 degrees) for the bulkhead the compass can be mounted into. I vaguely recall (as usual) that the C-25 bulkhead is at or slightly above the maximum angle for most bulkhead compasses. But they can be mounted at that type of angle--you just might end up using the top of the card (numbers furthest from you) rather than the front.

Had a talk with Ritchie's VP of Sales and Marketing today. It seems that the BN-202 cannot be mounted into a bulkhead that is sloped as much as ours is. However, Ritchie is manufacturing a compass that will work in a bulkhead up to 35 deg slope. It will be on the market in the fall of 2006. I gonna get one

Dan,

You might want to consider the Plastimo Contest 101 compass. It's available in 10-25 degree inclined bulkhead version, but the really cool thing is that it can be read from both outside and inside the cabin. Looks like it makes a nice skylight.
