This 152M / 499FT Spanish luxury liner is the largest known shipwreck in our waters. Launched in 1923, Cristobal Colon was the most advanced liner design of her time. She crashed into a coral reef at a speed of 15 knots on October 25, 1936. Today, she lies in 9-17M / 30-55FT of water with her wreckage scattered across 9,290SQ M / 100,000SQ FT of sea floor. Gigantic in size, she offers endless hours of fascinating exploration examining boilers, steam turbines, propellers, drive shafts and ship parts.
