Simrad Rate Compass vs Fluxgate Compass

The basic question, is the RC42 worth the $200+ difference in price from the FC40.

The "system" currently has B&G T7, 3G Radar with RI10. It will eventually add an AC12 based AP system with linear drive.

Re: Simrad Rate Compass vs Fluxgate Compass

I have the same exact setup in my Sabre 36 - NSS7/3G/RI10, Autopilot is composed of an AC12,RC42,RF25,AP24 with a Raymarine Type 1 linear drive.

The RC42 steers the boat nicely even in a rolly sea state. I have it mounted down low under a settee, near the mast. I don't have much to compare it to but I didn't consider the FC40. I was looking at the Airmar H2183 but decided on the RC42 for ease of calibration (using the NSS7).

Best of luck.

Yes. Very much yes. So much so that you should hire someone with a baseball bat to hit you on the head if you try to buy the FC40.

I don't know why they still sell the FC40, unless it is for purposes other than controlling an autopilot.

Don't skimp here - a rate compass pays GIANT dividends in an autopilot system. The difference is night and day. Black and white.

Get the RC42, or another rate compass like a Maretron, Airmar, etc.

Did I mention that saving $200 on the FC40 will be a huge mistake you will regret?

EDIT: I just noticed you have a Cascade 36. I have sailed on one of these and they are very responsive boats (a real surprise if you let go of the tiller for a second!). A rate compass will tame this thing down to barely moving the rudder at all. A non-rate compass will have you swinging back and forth and yawing like an amusement park ride. You will probably mess your pants running in large seas with a non-rate compass on this boat.

Re: Simrad Rate Compass vs Fluxgate Compass

Ok...ok....put the baseball bats away, I'll get the RC42!

Like most people I'm always looking for ways to save a hundred or two when I can. This looked like one place it might be possible. But if the performance variance is that good I have no problem spending the extra bucks.

Now I'll just patiently wait for a good deal to show it self on one.

Thanks for the info all.

Now is boat show time - see if Simrad, or one of their dealers, is offering discounts for the shows.

Re: Simrad Rate Compass vs Fluxgate Compass

I sailed a boat that had no rate, then we upodated the system. The benefit was obvious. Get one if you believe you need one. They work as advertised: more accurate steering, less hunting, less energy consumed.
