The upgrade to the Tigress is the Lofrans Falkon Horizontal Windlass which has to chain gypsies. The problem is this unit is way more expensive, like $6,000.
We have the IP 35 and have all rope on the port side with 20 feet of chain and then on the starboard side 250 feet of 5/16" chain on a 55lb Rocna. In 15 years of use, we have never used the second anchor.
