Lost Necky Gliss. If found, please return. Kern River area

I lost a Necky Gliss out of the back of my truck at the top of the canyon between Lake Isabella and Bakersfield. When I went back to get it, it was already gone. I was kayaking with my kids. We are a family of five and now we only have 4 boats. I am super sad about it and hope to get it back. Any tips?

Thanks a ton!
