What if he is cremated first...
Then take his ashes out on the viking longboat and then set it afire.

Backyard Renegade wrote in message I have a
friend who is trying to commission me to build him a small
viking type ship, maybe 20 feet... Only problem is he also wants me to
put him in it and send it to sea on fire upon his death. I did not
mind so much when he asked me to do it, but when I finally realized he
is serious, I kind of got freaked out. Still don't know if I am gonna
build that one, probably not. Scotty
