We have travelled the ICW
twice from Newport
, Ri to the Bahamas
. Our mast
is not as tall...60' but we have 5'6" draft
. The northern bridges are pretty true to 65'. Once you head
south of Norfolk, VA it gets more difficult to judge. With your depth
you should be able to use half to low tide to pass through. The ICW
needs planning for each days passage
and tide and constant attention to markers. Always honor the floating markers since they change to mark shoaling. Any day trips you can do outside would help with bridges, especially in Florida
I did my first overnight from St Mary's River to Cape Canaveral. It was a straight shot offshore
with land lights always visible. My husband and I actually stayed awake most of the time with only cat naps in the cockpit
. It was an easy run.
Good luck. If doing the Bahamas
try to find the "Explorer" charts
for the areas your going to.
