Another thing that might matter is that you might actually want the paravanes to work best at slower speeds, regardless of efficiency at higher speeds. When the weather gets really bad, we slow down. We also want the stabilizers to work their best at that slower speed. Just something that you might want to figure in. Our paravanes are backups to our active fins. We don't deploy them unless we expect bad weather. We like to be ready for Murphy ahead of time rather than trying to deploy the paravanes in rough conditions. So our situation may not apply. tr
