Stabilizers?

[FF]

That the boat moves with the waves is not the problem , the question is how soft is the roll reversal?


The round bottomed boats are usually the softest & slowest roll period , less problem to get used to.

Flume Tanks is a system of controlled flow of water from one side to the other - it is occasionally seen on ships.

Gyro's tend to work best on lighter hulls.

Active fins tend to work best on heavier displacement hulls.
