Captholli, I do agree with you and your assessment on seakeepers. They REALLY shine at rest and slow speeds of 12 knots and under (hull speed). I have found they do help running fast, BUT only marginally. Maybe a 20% improvement. However the boat in question is a slow one with a top speed of 10 knots. Zero speed Stabilizers in comparison are only marginally better at rest or perhaps better than marginally but not nearly effective as the Seakeepers. That being said I thought about mentioning paravanes, but at rest they don't do much of anything usually. On the mangusta you mentioned. I've heard the Humprees system works very well on a boat like that, and simply relies on tab's. I've used it and on a vessel with a 28.5 knot cruise it worked well. So maybe those and the existing seakeepers would be the way to go. I too have seen a combo of seakeeper and stabilizers, but on a lot of boats under 100' it's just too much weight and components usually.
