Thank you Robin, indeed the easy way.  I happen to work with direct access to a multi roll chartplotter...so it was my first thought....  indeed full digital is better...... 

It does show also how much mother nature has chiseled away in 38, 55, and other major blows.  I spoke long years ago with '38 survivors and saw photos they had of the Napatree and Sandy point area.  The demolition was incredible. 

My mother and late grandmother barely escaped Carol in 55, as they were on the Ocean side of Venetian Harbor, and nearly trapped, with water through the first floor. 

In my own travels since a small child and later bird studies on flat hammock and other places, I see unrecorded yet constant subtle changes in some of these areas.  Shoals shift and change, depths change a bit..etc...   A reminder not to push ones luck with blind faith in charts, paper or otherwise.  Many areas have not been surveyed in many decades.

There is an "obstruction reported" 1983 a short distance from West Cove Noank.  I have stood on it less than 18" under extreme low tides. It was almost breaking water after one winter storm.  I did my own little survey as we used to trap it for lobsters at certain seasons.  It is actually several obstructions that are more extensive than you would ever expect from the mark, and a true threat to even shallow draft vessels.   I have somewhere a satellite shot midwinter, which clearly reveals the danger.
