how many US Sailing members are multihull sailors?

How many multihull sailors would join (again) if they knew the money offset the Alter Cup costs?

$200 per qualifier sounds a little steep for those who'd like to sail one, but have little chance of making the cut. Maybe $200 if it's a 3-4 day event... How does that stack up against the entry fees of other (class, region, etc) events?

And I'd second Karl's suggestion of a surcharge at local regattas (under certain circumstances) as long as it was guaranteed the money would go directly to Alter Cup and not "administrative expenses" or whatnot..
