Why that brand and if you don't mind cost parts
cost install
[/FONT][FONT="]Sorry for the late reply.
For the Magnus Master Rotor system was crucial:
We have no hydraulics, but a Victron Quattro 3000 and a generator (7 KVA), so an electrical system is an advantage.
We definitely did not find a place for a gyro system.
Unlike finn stabilizers, the rotor system can be installed at almost any position laterally in the hull. At Dodo, there is a lazarett in the stern, in which the Rotor found its place.[/FONT]
[FONT="]For Dodo (LOH 40', beam 14''-6', 20 t loaded) a single MM 14/1000 Rotor system is sufficient and thus only a single hole in the hull.[/FONT]
[FONT="]The Rotor system needs a maximum of 1500 W, so no problem for our Victron Quattro and the alternator.[/FONT]
[FONT="]No further costs for maintenance.[/FONT]
[FONT="]The single [/FONT][FONT="][FONT="]MM 14/1000 Rotor[/FONT] for a GRP hull is about 37 k Euro without installation. [/FONT]The installation will be about 5 k Euro, whereby the battery for the stern thruster must be moved etc.

Swell was only 3 to 4 ft but an 8 second period so the boat was rolling a bit without it on. I often turn it off (unit is locked and doesn’t precess) for a few minutes, and then on again to experience the delta.

[FONT="]Here in the Baltic Sea West we have a wave period of 4 seconds at 3-4 ft, 3 seconds at 2 ft, because of the shallow water. A wave periode of 8 seconds I would call comfortable
