Hi guys. I have a design I'm working on to prevent waves from washing into
the open hatch. The freeboard on my sub calculates out to about 20 inches or so
but, not being a math wizard, God only knows what it's really gonna be. So
here's what I came up with. I found a FAT innertube on Ebay and it will be
inflated just before I open the hatch, raising the shield.
I haven't shown it on the sketch but some little springs will be attached
to the hinged plates to pull the shield down when the air is released into
an MBT vent nipple.
OK.....some water is still gonna get in, but maybe not enough to cause a
problem. Got any thoughts ?
