That brings to mind a fellow I met in the 1990s. The Lord told him to sell his gas station in Iowa and bring Jesus to the people of the South Pacific Islands. He moved to Ventura, CA and bought a ferrocement sailboat that wasn't sea worthy. The owner had just used it to live aboard.
As he made his plans more widely known, people tried to talk to him and when he wouldn't listen they at least tried to help with offers of charts and sailing knowledge.
He didn't need charts. He had a globe and the Lord. Even the seller was feeling guilty.
On D-Day he set out single-handed to pick up his family in San Diego. He never made it. Fortunately, the Lord placed his boat safely on a beach 13 miles south of Ventura.
