CNN.com – Cubans try floating vintage car to Florida – Feb. 5, 2004
The first time this group of Cubans tried to immigrate to the US, they set sail in a 1951 Chevy pickup. This time they upgraded to a 1959 Buick that they sealed up to make seaworthy. They were halfway to Key West when they got caught. They even hooked up some kind of propulsion system, presumably a propellor, to the V-8 engine. I wonder how many knots per gallon they got.
This story reminds me of an episode of Junkyard Wars. The two teams had to build boats out of scrap equipment and engines that they found in a prepared junkyard. I think the show would have been a lot more exciting if they had made the two teams pilot their car-boats through shark infested waters.
