Where are you from in Oregon? Your story sounds very familiar. Medford area?
I ran across a very entertaining blog the other day of a wheelchair bound fellow in Florida who is rekindling his love of sailing. He has recently taken delivery of a new boat and is blogging about his experiences. It is a good read for all, but maybe especially for someone with similar challenges. It can be found here
BTW, Dan (sailingdog) is a great resource around Buzzards Bay. He'll not steer you wrong. He does bite, however, so be careful.
