Does anyone know what material would be used for the clear parts? Plexiglass? Especially given that this is sort of deep in open waters.
And given the materials, what would be used for the joints?
I’m thinking the the floor and knee walls would be a poured cement. But how would you get a water tight seal between the material for the base and the clear material overhead? (Can you provide links to products that could make this connection)
Any suggestions or help would be appreciated.
