This video captures the SIG45 sailing fast in the Bay of Cannes.
The catamaran seems to sail very fast, and very smooth. It doesn’t take much effort to achieve such speed.
Note that there is virtually no spray and that the boat stays totally dry and calm even at these speeds.
The boat is also spacious enough to sleep 6 persons in three double cabins. In addition there are two heads, a large galley, dinette and nav station.
