superyacht carrying 22 sank in storm

56 meter (184')

The coastguard said the yacht was built by the Italian shipbuilder
Perini in 2008. The luxury vessel has an aluminium hull, can reach a
maximum speed of 15 knots and can carry 12 guests and a crew of up to
10, according to online specialist yacht sites.

Reports in local media said that a waterspout had hit the vessel. A
waterspout, which roughly resembles a mini-tornado, is a column that
descends from a cloud to form a rotating mixture of wind and water
over a body of water.

Some fishers reported spotting a small tornado off the coast at about
3:55am. Shortly after, they witnessed a distress flare allegedly
launched from the vessel. The fishers approached but recounted seeing
only "scattered remains of the sailboat floating in the water".

Storms and heavy rainfall have swept through Italy in recent days,
with floods and landslides causing major damage in the north of the
country after weeks of scorching heat.
