Okay, well not exactly normal velcro. This stuff is made out of steel, and one square meter can support 35 metric tons!

I could see attaching one side of the velcro to one seastead module, and the other side on another module. Then you just use a tug to push them together. Presto…connected modules!
I wonder what kind of ripping sound this makes when you tear them apart, though!
Exactly what I need, thanks 
That rocks! I’ll take it!
to hook up my chainmail lingerie.
Of course chainmail lingerie sounds nice too.
The problem with steel is, it work-hardens and becomes brittle. Anything that can do that, won’t work for long. The seas are never still, which is why boats tie-up with some sort of padding in between.
Add that salt water is highly corrosive and water is, itself, considered the “Universal Solvent” and you have the un-making of whatever attachment system you intend to use, long-term.
Not shooting-down the idea, itself, just the currently available materials.
