Legs and Cables

  1. Stainless steel 316
    Should last well and not too costly.
  2. Titanium
    It does not rust in seawater. Sea-life growing on it can not harm it. The price has come down to where it seems a reasonable choice.
  3. Aluminum
At the end of each leg will be some kind of "Heave Plate" so it does not go up too fast. This could be like a 6 foot by 6 foot flat plate of metal.
