Frank,
An interesting device! I like the way you attacked raising the leafs
of the shield.
You probably already noticed that in one view of your drawing your hatch
cover is inside the shield and in the other it's outside. If your
concerned about splash as your hatch is being opened, you'll probably have to
hinge your hatch so it's more like your bottom view, or redesign
your shield so it's much larger then just the hatch opening.
Great design though!

Subject: Re: [PSUBS-MAILIST] Splash ShieldHi 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 ?Frank D.
