Onderwerp: [PSUBS-MAILIST] Dome alternative - flat acrylic endcap

Hello.
Apart from acrylic dome endcap I am considering an alternative - flat 
acrylic endcap. This would be a flat window about 59" (150cm) in 
diameter, 10" (25cm) thick. That kind of front side would be very 
inefective hydrodynamically. So there should be another acrylic layer, a 
thin dome with holes in it to allow flooding it while submerging. This 
would increase the hydrodynamic effectivness and would also help 
protecting the main window. I think this could be cheaper than 
purchasing 59" od, 3" thick dome for the main window. What are 
disadvantages of that solution?

Thanks
d.
