H260 and tide goes far out grounding it, mud squirts up bottom hole into ballast tank?

Here in Houston when North wind blows the water drops at my marina to 1 foot from 5 foot normal, grounding boat. Water level in h260 ballast tank hole is 10 inches lower than normal. I wonder did designers test to see if mud squirts up the partly unsealed bottom round tank hole in this situation? As a positive with less water in tank the strain on dock lines is less. Just wondered. I will swim under later and poke finger in to feel for mud. AND SO FAR THE SWING KEEL SEEMS FINE. Hmmm. D

Why is your ballast tank valve partly unsealed? If you are losing water at low tide.... then you are also losing water when heeled over. Not good.

Next time on the trailer... crawl under and see if your gasket has left this earth. There should be a circular neoprene gasket around the lip of the valve cover plate. I had to rebuild mine on my H26. I used goop. I have a pic someplace but can't find it right now. With the tank valve open I took some masking tape and made a dam around the lip of the valve cover... then I poured a tupe of goop onto the valve cover and let it sit for a few days..... now I had a hard rubber coating about 1/4" deep on the valve plate. When I closed the plate tight, it made a water tight seal.
