When my brother passed, his yacht club had a great practice. Out in the bay all the boats formed a loose semi-circle well downwind of the boat with his widow. She stood on the bow and scattered his ashes (facing downwind!)and we dropped a wreath on the spot. Then all the boats came by single file and each dropped flowers on the spot. After that everyone did what my brother would have loved - had a great party at the club. In retrospect, I know where my brother "is" just as well as the graves of my parents.
