Cybercylinder

In this novel a young Artificial Intelligence (AI) guru invents a new
ski called a Turboski or T-Ski. It's a platform for use on water and
snow which uses small side-mounted turbojets to propel the user
out of danger. The youth, Webster Sterling, is an orphan who
attends UCLA .
The young inventor inherits a 220-foot yacht called an Aquaclipper
made in Hobart, Australia where the company owner wills the craft
to the young Aussie. The ship, which he names Bald Eagle One
or "Baldie" is moored in Long Beach, California where T-Skis can
be tested.
Web advertises to find surfer students at UCLA to live aboard his
craft and continue to develop the T-Skis.
Web, the consummate inventor, develops a device to open tumbler
locks in the event the combination is lost. He plots to use the
new Cybercylinder to rob safes which have the most money and
valuables but the least security-- casino cruise ships plying the
eastern Caribbean.
Over the span of seven months, the new team of Robin Hoods successfully
robs huge cruise ships and a casino from St. Martin to Aruba. The FBI,
Scotland Yard and INTERPOL launch huge investigations to solve the
crimes and return the stolen valuables. Because of the adroit use of the
Cybercylinder, huge sums are stolen with no clues left. The detectives
are forced to admit that they are perfect crimes.
