I have a 46' boat
with a 65' mast
(can't do the canal) and 5'3" draft
. I tried going close to the shore once going north up the Bay. Going between Eph and Prissiwick. Saw breakers on Prissiwick. Guess I got too close. I got nervous and reversed course, then standing off the shore and going around the Cape clear of Prissiwick. I guess I should have gotten closer to the shore and north of Eph, but finding that passageway would save some time.
I guess the trick here is to hug the shore so as to keep north of Eph. There are some 6' depths on Eph. That leads to a tight pucker factor. Do you run that channel in flat weather
