I got the power ratio numbers from the winch performance information for the Grinder 40 on the Defender website.
I see that 1st & 2nd gears on the Trimmer are the same as 3rd & 4th on the Grinder. 14 CM of line recovery per handle revolution in the fastest gear for the Trimmer. One of the metric folks on the list help me… that’s, what, 5.5 inches? And 1.4 CM in the lowest gear is about 6/10ths of an inch per revolution? Max working load is 1870 pounds for both the Grinder & Trimmer. I wonder what the sheet loads are on a 155 on a 38 mk2 in 15 knots of true wind? According to the Harken calculator, for my 135 in 20 knots apparent (which is around 13 or 14 true) the sheet load is 969 pounds.

Winch replacement for a C&C 38MKII I am not sure where Rick got his numbers. I looked into this recently after an elbow injury made me consider replacing my Baronet 28s. The Pontos Trimmer 4 speed ($1600) has a power ratio of 113 in its maximum power gear. If I replace my winches at some point, that is what I am planning to use.

(Which, BTW is $300 more than a Lewmar Ocean 40 and $600 more than a Lewmar EVO 40) And it gets line in fast. And it shifts gears automatically at a comfortable 25 pounds on the winch handle. But… The ultimate power ratio in the lowest gear is still a 40 – which means it has the same power as the Barient 24 that came as the halyard winch on my 38. (And that I have installed as primaries on my C&C25) Ron, you indicated dissatisfaction with how hard it is to grind in your 155 with the current Barient 28’s. The current Barient 28’s have a power ratio of 52 – the same as the Pontos 52’s that sell at Defender for $3400 each.
