Potential low-cost, shallow-water small-family scale, semi-submersible platform, using refurbished/remodeled travel-trailer for a cabin.
Based off the Little SSLV:
This vessel was specially designed for the Navy’s Lightering system for deployment of barge bridges. The vessel was designed to fold up and fit into a shipping container and be able to run on its anchors while installing anchors for the barges for some 2000’. LITTLE SSLV is perfectly suited for small operations of bridge, dock, pier, and bulkhead work. It is trailer able to reach areas inaccessible by direct waterways.
Shown with 28ft Airstream for scale. Uses 3 deck sections 7ft 6 in bt 36 ft, for a bean of 22ft 6in, and LOA of 36 ft, 12 - 22ft trusses for legs, spreaders and beams, expect diagonal stays with turnbuckles for added rigidity and strength. probably use 4 suction anchors, in Tension-Leg mooring, or 8-12 weighted catenary lines with anchors.
With the trailer centered, it gives room to pass at either end, plus 2 complete deck sections as outdoor space.
Could orient approximately East/West and have a greenhouse along the South side, and shop-space/storage on the North side (Northern Hemisphere, such as Gulf of Mexico)
When disassembled, it would be completely trailerable…
