It can flip like any other
monohull. If it gets sideways to a large, steep, breaking wave the
hull wants to slide down the wave but the
keel in the
water acts enough like a
drogue that the
mast is well below the horizontal, then the breaking crest slaps the underside of the
hull and over she goes.
Any boat can be flipped under the right conditions.
It has an interesting rig though. Did you notice?
Have fun
