US SAILING does have a program. See
http://ussailing.org/olympics/Paralympic/Locally at Sail Sand Point in Seattle, we just got two 2.4 meter R's. In the process of rebuilding them for our sailors with special needs. We also have a Trapseat for the Hobie 16's. Trapseat Worlds were held next door in B.C. Canada in 2005.
Plenty of programs available, just have include them in your local sailing centers.
