Northport Yacht Club is a private club.  Membership is by invitation only.  We do not accept non-sponsored applications.  If you are interested in becoming a member you must be sponsored by two members in good-standing.  One of them will get you an application package. Applicants will be interviewed shortly before admission.
There is currently a several year long wait list.  While non-boat owners are admitted for membership, boat owners are given preference.  Your sponsor will be able to give you a more exact timeframe.  This is a Yacht Club.
