A pod in the sea
Single occupancy, or deluxe dual occupancy
Unbreakable glass window in front
Lying down, controls to left and right, retractable steering wheel
Water purification system letting in drips of water into a tank and filtering from salt to freshwater
Pod can go vertical and rotate so you can be upright whilst diving below or face down for scuba like experience
On the surface the window can be pushed out and retracted and be convertible, for calm seas and looking at the stars at night (lovely views in the middle of the ocean in total darkness)
Indestructible to smashing against rocks or teeth of sharks etc
Womblike feeling of being totally safe in the middle of the sea, stormy waves crashing over you 
Fixable motor parts and homing distress beacon GPS and autopilot for traveling whilst asleep, avoiding boats and other hazards
