No, you can go out at Angelfish at high tide. Controlling
depth there is a matter of dispute, I have been through there hundreds of times with a 5'
draft, including MLW, without ever touching, but I believe the controlling
depth to be no more than a few inches more than 5' at MLW. Nonetheless, that means you only need 1 additional foot, even with our marginal South
Florida tides you're going to get that on the average day. Very important note: you'll have plenty of
water all the way through Angelfish Ck, the controlling depth is a very short stretch (a few yards!) just inside #2.
As far as Hawk Chanel at night goes, there are very few lighted marks in that region, and as soon as you turn S coming out of Angelfish you will be in an area with a lot of
reefs (Basin Hill Shoals). You will need either
GPS to navigate, or a crack crew... If you follow the submerged cable you'll be fine. Prevailing winds USUALLY allow you to do this. pete
