Understanding NOAA bridge vertical height
Just wanted to bounce an understanding off others to see if I am correct.
If the local NOAA chart shows a bridge with 35' vertical clearance and 8' of water, does this mean that;
At high tide, there is 35' vertical clearance. We have a 6' tide here in Tybee Island, Ga so at low tide the bridge would have a 41' clearance.
At high tide, there should be 14' of water under the bridge and at low tide 8'.
Is this information true?
The reason I'm asking is that now I have a boat with a 29' height. The C-27 I am looking at has a 39' height. Thats cutting it really close but I don't want to give up the wonderful slip I have in the marina.
