Larry,
Harken has changed its product line, shifting to the "radial" drum, and the 42 and 44ST class-approved for primaries are no longer available in aluminum.
What Harken now sells are:

40 or 40ST 39.90:1 and 13.5:1
46 or 46ST 46.50:1 and 11.7:1

There are still some bronze or stainless 44STA's available, but they are very heavy and the price has gone through the roof, like $3,000++.

We need new primary winches, and Harken's look best. Are any of them class-legal??
