As a 501c3 non-profit with no full-time staff, NUMA depends primarily on royalties from Clive Cussler’s best selling novels to keep the work of NUMA going. However, we always appreciate donations from fans. As our way of saying thank you for donations, we provide varying levels of merchandise depending on your donation. The best way to provide a donation is to visit the shopping area of our Web site. NUMA’s Mission is to preserve maritime history. Your donation to NUMA will help us accomplish that.
