Stabilising

There are a lot of stabilizing options. The simplest and most cost-effective ones are paravanes. Then there are active fins (multiple reliable suppliers), the DMS MagnusMaster, and gyro stabilizing (e.g., Seakeeper, Quick, and DMS AntiRollingGyro). Each solution has its own set of pros and cons.

LRC58-03 has active fins installed, LRC58-04 uses paravanes, and LRC58-05 has a Quick gyro. XPM78-01 has paravanes, and XPM78-02 will get DMS MagnusMaster's.
