Unless you have a boat over 65 feet with an auxiliary motor and loads of sea experience, that is not a way to go, sorry.
You should also have a small crew.

On a positive note, having a solid 4x4 vehicle, well supplied with extra tires( note plural) gas tank spares, etc is a good start.

Or take what you need.
