Sensors

I cannot recommend the A+T wind components enough.

Have used for over 8000nm flawlessly, and upgrading all the boats I race on based on superior specifications.

Email me for more information.

This is an interesting question, that latter part (h5000 expansion modules) is one that may need to be addressed directly to B&G.

However in a practical environment, a 1Hz output from a speed sensor is reasonable considering the rates of acceleration/deceleration of a reasonably large mass.

In terms of sample rates, considering paddle pulses are in the region of 4 pulses per second per knot, then a 1Hz output is pretty good. Consider a 0.3kt change in speed at 6 kt, is a change of only one pulse per second.

Motion sensing for correcting wind dramatically enhances your wind speed and angle sensor input. As you can appreciate the induced winds by the motion of the masthead are not insignificant, especially in light/moderate conditions with a seastate.

Motion corrected winds require much less damping resulting in a more responsive wind reading as well as being more accurate without using the averaged out peaks and troughs of an oscillating sensor input.

So, my recommendation is definitely to use motion sensing if available. All half decent instrument systems use motion correction/gyros, like A+T, RacingBravo, FaRo, H5000 etc.
