Existing records.

The existing 24hr distance record for a Jetski is 600 miles, done by a Croatian.

A deaf and blind man rode from Land's End to the isles of Scilly and back in four hours with a passenger giving directions.

Driving a Jetski for 7 hours produces as many hydrocarbons as driving a car for 100,000 miles.

An amputee circumnavigated the Irish coast on a Jetski: 1000 miles in 19 days.

Alvaro de Marichalar took a Jetski 5,320km from Hong Kong to Tokyo, a trip taking 11 weeks. He also took four months to go from Rome to Miami, as well as other crazy shit.

Hopefully he won't find this page and take my $100.

Inspiration.

Henry brought up the idea of riding a Jetski to Alaska, and I proposed that Bellingham might first be a reasonable destination. I offered him $100 to do it, and since he has not yet left I have amended the plan to be $100 to the first person to accomplish this goal. Miles has pledged another $100 to the first person to arrive in Juneau.

Will it be done?
