In addition to the winners of the 10 Area Championships, the Hobie Class Association is asked to designate two representatives, Performance Catamarans is asked to designate two representatives, and another class chosen by the Alter Cup Committee is asked to send a representative. Plus, the Tornado Class is asked to send a representative.

One slot is taken by the past Alter Cup Champion. And three slots are available by petition from individual sailors.

Sometimes it is hard to understand who got there by what route, but it is all explained on the entry list at the US Sailing website, http://www.ussailing.org/championships/adult/usmhc/alter05/entries2005.htm
