On Wednesday, September 5, 2001 the Ikan Tanda, a bulk carrier, ran aground off Scarborough on the southern Cape Peninsula's Atlantic coast, at the mercy of what has been described as the worst storm for 50 years. The same storm blew a fishing vessel onto the breakwater in Table Bay.
10 beaufort:
wind:48-55 knots sea:waves;9-12.5 m
Very high waves with long overhanging crests, the resulting foam, in great patches, is blown in dense white streaks along the wind direction. On the whole the sea surface takes a white appearance, tumbling of the sea is heavy and shock like. Visibility affected.
8 beaufort:
Wind: 34-40 knots Sea: waves; 5,5-7,5 M
Moderately high waves of greater length, edges of crest begin to break into the spindrift, foam blown in well marked streaks along the wind direction.

Lloyds class 100 A1, but should be limited to aquariums to prevent rolling. This looks odd, but even at 12 beaufort this type survives (when driven carefully).
