Spreading remains/ashes.

[Raider Ronnie]

On June 5th I got the call that I feared I would eventually get.
My younger brother was found dead of a drug overdose. 49 years old.
He made it clear to everyone that he never wanted to be buried in the ground when he died, wanted to be cremated. Wanted nothing to do with a Church Mass.
Tomorrow I will be taking about 10 of my immediate family, including his son, my parents, sisters and a few cousins & uncle out on my boat to spread his ashes in Boston harbor.
It was he who about 30 years ago was the one who got me into fishing & he was the one who had a boat. Plan to spread them at a handful of spots he & I fished in happier days back when we started. Figure we will lay him to rest in the place he was happiest.

Anyone here done this type of thing and if so, how did you go about handling the ashes as the be respectful rather than just grabbing them with your hands or dumping them from the box we were given from the funeral home.
Thank you in advance.
