The final opportunity to volunteer for this summer’s Tall Ships Tacoma festival is tomorrow.

Organizers say about 1,500 people have signed up to work the July 3-7 event, but 500 more are still needed. Available jobs range from assisting in security to working directly with the ships’ crews.

The final recruitment fair begins at 5:30 p.m. Thursday at the Washington State History Museum at 1911 Pacific Avenue in Tacoma. Volunteers can also sign up at tallshipstacoma.com.

Volunteers must be at least 16 and commit to a minimum of two, five-hour shifts during the festival.
