[PSUBS-MAILIST] Hatch view port

[Jon Wallace via Personal_Submersibles]

 Ian, I think the weight of acrylic removed to form the conical shape would be overall insignificant (in totality) given that the hatch by itself is upwards of 70 pounds, but that's as good a guess as any.

Could it be that it's weighs less overall than a flat viewport? which in turn makes that hatch easier to lift.

One more thing...hey, am I the only one not working today...anyone know why George designed a conical viewport into the hatch rather than a flat one?
