Riffing on the concept development I've been doing in the Hexagon Archipelago concept, I think that a similar low-cost and highly reliable design can be achieved that looks a bit more traditional. A barge of dimensions 50' by 150' with rounded or angled bow and stern (could still be a stretched hexagon {--------} if that is an easier pour to engineer) has a simple concrete pour of vertical hull and flat deck inside a flood-able lock. The deck and hull are poured around an interior form made of an EPS block (or blocks) intended to become a permanent feature of the vessel. Exterior forms are removed, the lock is flooded, and the vessel is floated out. Perhaps at this point, semi-permanent (replaceable for wear) netting is placed across the open bottom for extra security in keeping the foam block(s) in place. This provides a very massive platform that will exhibit comfort and stability, has buoyancy that is not dependent upon water-tight hull integrity, has a broad usable surface, and can be post-tensioned at reasonable cost. (edited to add link to visual example of stretched hexagon)

You could copy Sewa ... and use bags of old plastic bottles. 😀

I might consider that for anchoring a mangrove for wave attentuation around the edges, but I like the idea of a platform under me that won't be torn apart by waves, much less wind. Richie Sowa's 'island' is confined to a marina, not even a bay.
