I am now trying to figure out the best stovage. There is plenty of space in the boat. This means that I have to be extra careful not to fill it up othervise the boat will be to heavy.
I have come up with a system cheap light and functional for locking the hatches. The first idea was with a rope in tension but it was not enough friction in the system despite the capstan equation. I took a walk and used the rope in compression instead. That works fine. I use rope hinges.
