FWIW...I just took off my Autohelm linear drive. After many years it finally died. It was the Series one, or rated up to 24,000 lbs. It performed flawlessly in all sorts of weather on all points of sail. I am manic about sail balance and no more than 5 degrees of helm and reefing early (especially offshore)
Corsair spec displacement is 17,100. But I am sure all up she is pushing 19,000. I will once again replace it with the Octopus hydraulic unit of the same rating. I am hoping it is an easy swap.

So for a LF38 at a published displacement of 16,000 lbs (which means in real life, it’s more like 19,000 lbs loaded or more…), you’d want the autopilot to be rated for at least 24,000 lbs; closer to 30,000 lbs would be better. The Octopus drive is rated for 33,000 lbs, and the ACU-200 course computer will handle the current for that drive under all conditions you’re likely to encounter. That’s a much better safety margin than the SPX-5 which is rated at 16,500 lbs max displacement.

I do have a Raymarine SPX-5 wheel autopilot which I had installed on my 29-1(it is now currently at Raymarine getting the computer repaired). A 38LF is right at the max displacement limit for a SPX-5, and I was thinking about giving it a try, but I am strongly thinking about following Fred’s recommendation in getting the EV-200 Sail paired with an Octopus 1212LAM12 hydraulic linear drive.
