You are very specific about the
boat you want and equipement. I am betting your going to have a hard time finding the exact
boat unless your willing to compromise or have a large
budget. Like 500K or more.
Have your checked out the thread "Cheap mulit hulls" That's not the exact name of the thread but almost everyday someone posts a boat that has been listed via ebay, craigslist, sailboat listings, ect. that is reasonably priced.
