Interesting what you are saying Graeme, I read this post in another forum, quote:
It depends on the vintage and model of the Raymarine course computer. I've gone through 6 generations now, (ST5000, 100, 100Gyro, S3, SPX30, and Evolution) and each one is better at course holding than the last. The ST5000 vintage would not steer off the wind in a seaway, oscillations would start and shortly thereafter it would give up. The first generation with gyros (100 Gyro) was a bit better, the next (S3) quite a lot better. The next two a bit better in each case. The fluxgate compass can contribute as it has to be pretty heavily damped to remove all the motion inside the can. The last two generation course computers will hold a very accurate course, downwind in a seaway, with the boat unbalanced, in all conditions, and never give up. The last one has the EV100 solid state MEMs, and is easier to calibrate and perhaps slightly more accurate steering. Downwind, the helm will react to the rising stern quarter prior to any yaw, just as you would if you were at the helm. I've no experience with the Pelagic, but I will say with conviction that if you haven't tried Raymarine's latest, you haven't tried Raymarine. There is a night and day difference between the old and the new. End of quote
