I would think what's more important is weight of the anchor, chain, rode size, etc.
I actually purchased this for my then 32' boat (which by the way had a heavier anchor and much more chain than I intend for the T37). The rating was in spec then but now with a larger boat yet lighter anchor gear, it's supposedly not up to the job even with the larger motor.
If I was a cruiser I would put it up on ebay and opt for something more substantial but I'm not. At best I'm a weekender and if my wife can pull up the anchor as she does now, the Dorado is certainly up to it.
