@Jens On July 26, 1953 Fidel & Raul Castro led the Cuban rebels in the attack on Moncada garrison at Santiago de Cuba. When purchased in 1973 ORANJE NASSAU was renamed XX ANIVERSARIO (20th ANNIVERSARY not birthday) to commemorate that action. Rgds

Any idea what the 20th birthday name is about?

She was used to transport Cuban soldiers to Angola to fight South African troops.

Interesting but so sad to see her in such condition.
