Re: Checking depth sounder calibration (Clipper Cove silting question too)
I have never bothered with that offset nonsense. I just drove my boat up to some thick mud bottom and when it touched I was aground, read the depthsounder: 4.4 So, if it nears 4.4 I'm going aground. No math involved.
Clipper Cove is NOT silting up. If you didn't run aground, it doesn't matter what your sounder read.
My 25 years of experience indicates that for a yacht with a nominal 6 foot draft, one needs zero water (in the tide table) or higher to get in or out. Simple.
