This idea stems from my need for sumwhere salt proof to store my trike whilst sailing and also needing some way to launch trike when I need to explore

Basically it is in the traditional shape of a sub being a long cylinder with pointy ends with several important differences.

The whole thing is constructed out of see through plastic/perspex

The ends contain entry/exit conning towers and onfold from cylinder allowing for easy access.

Reason for this is due to my trike having a rollcage and solarpanel which is my primary source of power.

Whilst I can reverse it is not trivial to do so, always easier for us Aussies(emus and roos) to go forward anyhow.

No bulkheads apart from at the ends means the see through pladtic sides of craft will need to be reasonably thick with the ends of the cylinder jpined along what would form the base of the craft up to just below a persons shoulders when seated inside.

This should allow a splendid view on all sides apart from the balast tanks hich will be part of the floor.

propulsion will be via several jets embedded into both ends to prevent issues of launching when beached/fouled
