Sailboat on the beach at Treehouse?

[Seamuis]

@johng What I am inferring is they dig a trench straight out to deeper water and to start that trench so that the keel slips into it, yes they need to dig it six feet down and perhaps they will not be able to dig six feet all the way out. Once upright and close to six feet divers with air hoses can agitate the sand below while the tow boat pulls.
