This study summarizes the current status of sail
assisted commercial steamships,
the industry's strengths and weaknesses, and why it isn't widespread today.
Ways in which free flying kites used in place of conventional sail may
ameliorate some of these negatives, while incurring new problems, is examined.
The specific advantages and limitations of crewed and self-sufficient KiteTugs©,
a new class of lighter than air sailing vessel/sail assist device are investigated.
A detailed breakdown of potential KiteTug cash flows and cost-effectiveness is included.
|Current Status of Commercial Sail|
|How Can Kites Change This?|
|Costs and Cash Flows|
|Likely Annual Fixed Costs for the 30,000 sq. ft. KiteTug©|
|Costs and Cash Flows of Smaller 15,000 sq. ft. KiteTug©|
|Will it Happen?|
Dave Culp has fiddled with kite powered speed sailboats since 1978. Dave Culp Speedsailing (DCSS)-designed boats were entered in the John Player World Speedsailing Trials in Weymouth, England in 1978 & '79, the Schmirnoff World Speedsailing Trials there in 1980 &'82. Dave built, transported, and entered his own boats in the Johnnie Walker World Speedsailing Trials in Weymouth in 1986 and 87, and in the Ned Snead Invitational Speed Trials, Lake Buchanan, Texas, in 1989. Dave makes his home near the San Francisco Bay, in California, where he continues to develop kite sailcraft.
