Description

The idea is to use a tension circle to make a marina.

Detail

  • Material issues - concrete, foam inside wall. Since it does not go far below the water foam and concrete should be ok. With foam cracks in the concrete will not be fatal.
  • Tension members could be plastic rope or steel cable (note they are not in drawing above)

Requirements Analysis

  • Safety
    • It is very wide compared to boats and so should be very stable
    • Wall is filled with foam so essentially unsinkable
    • No active ballast controls so no chance of that going wrong
    • Not clear how we make boats inside safe during hurricanes
  • Comfort
    • Should have a gentle motion on normal days but significant response to large waves.
  • Cost
    • This should be one of the cheapest designs. It's very simple. Although it is as wide as a large cruise ship, most of the area is just cables over open space.
  • Pretty
    • Looks nice.
  • Modular
    • May be able to scale by adding wall sections. Can make multiple marinas.
  • Cargo
    • Very easy for a boat to come into the marina and transfer cargo to other boats.


  • Free Floating
    • Yes
  • Scalable
    • Scales up but not clear what the minimum reasonable size is.
  • Standards
  • Mobile
    • If tension members were removed from wall it could go through the water like a snake so moving was very economical.
  • Draft
    • Very shallow draft.
