Kites have the limitation of not being able to sail close to the wind direction. Square riggers , while being very romantic looking take a lot of handling and again are not close winded, Fore and aft rigs are the closed to an all round rig but the best by far is a Flettner rotor which can sail at 25 degrees to the apparent wind and provid 10 times the thrust that a fabric sail can produce for its area. These sails are powered by small electric motors which are run from solar pannels. It sounds odd to have a “powered sail” but these sails have been proven for almost 100 years and are about to make a big entry into shipping as we know it.

Fully automated , so no additional crew savings of 1000s of tons of CO2 NOX and SOX per year not to mention the knock on effect to the price of goods getting to their desitnation at a fraction of the cost !
This can not fail.

look up the sailing ship kwai that is running commercial trips in the south pacific kind of a hybid but still a step in the green direction

Sailing ships are not completely pollution free. They must be built, painted, maintained, repaired by people and tools that generate pollution in their manufacture and/or use.

Ssiling does require less of a crew now, but still people have to eat whether at sea or on land. That was a foolish shot. Note that pollution only shows up in Cities where it is concentrated, (lots of cars) and less trees. Answer: Plant more trees in the cities. Trees handle Pollution. Note: none, or minimal pollution in outlying areas of the country. I won’t live in a town with more than one stop light. Too much polluting while doing a useless activity. Why do you think that wealthier towns pride themselves in lots of them. Note: The problems Mr. T ran into when he tried to clear his own land. Sailing crew and cost can be fun and limited by taking on volunteers for the lesser experience jobs. People would come on and do this just for the experience of it. The Bounty takes on Volunteers for differing periods of time. Oh, and Global Warming; ain’t happening. Don’t fall for it.

I think that the range and power of alternative technology are damaged by being over-hyped. People read a couple of statistics and suddenly are experts.

The fact of the tall ship being in service is fascinating — I would have liked to learn more about it. The speculation on carbon footprint impact is pure garbage and spoils the article.

Love Tall Ships: Picture this: Cargo under sail !!! A bow thruster’s for in close Props for tight maneuvering all electric powered;by capturing wind!!! Its all right there And we can accomplish this, We just need to think and do…. We have this technology $$ 2 Build $$ 2 Maintain free fuel 2 operate!!! diesel ship coast $$ 2 build,$$ 2 Maintain $$4 fuel!!!

There are a few other sailing ships that have similar programs. One of the most well known is the “Picton Castle”(www.picton-castle.com) out of Nova Scotia, Canada. She is a sail training vessel that carries cargo in her hold all over the world. She uses the money made to help offset the cost of the world voyages that she makes.
