To make such tours accessible to those who are and are not physically challenged, companies make it a point that the meeting points are easily accessible by plane and at cheap rates. Booking can be made through your travel agent or you can make the reservation online. You can look at their itinerary for the year so you know where the ship is going on a certain date.
There are also sailing clubs for the disabled. Some will require you to pay a membership fee while others hand this out for free.
Perhaps the biggest achievement for those who are disabled is to compete against others that have similar disabilities. Established in 1998, the US Disabling Team competes in various races annually and the biggest one this year happens to be the 2008 Paralympic Games which will be held in Qingdao, China about 430 miles east of the Capital.
So whether it is just for fun or to race for the grand prize, adventure sailing vacation has no limits even to those with physical disabilities. This is because they can be trained to run the ship just as well as an able bodied person so they are able to set out to sea and return back to port.
