Slider--
While you may be technically correct, those passes do require local knowledge that is more than an infrequent visitor will have at his/her disposal, so I dismissed them out of hand.
In fact, the Sarasota Yacht Club maintains a plot of the supposed safe channel through Big Pass on their web sight, which is up-dated from time to time. We tried to follow that during a
cruise last April and, at mid-tide with no sea to speak of, hit the bottom pretty hard in several supposedly clear spots. Fortunately we were only creeping along and were able to back off, but, with that, we decided the effort wasn't worth it. (FWIW we draw 6.5'). Those passes are for the more adventuresome than we and those with (much) shallower draft.
Acadia--
The anchorage at Desoto Point is nominally at N27 31.326 W82 38.263. There is a shoal in the middle of the "bowl" with only 3-4 feet and another shoal building up in an easterly direction from the point by marker "12" that has only 2' of water so the best approach to the cove is heading in a southwesterly direction, toward the Cross, from a point on the northeast side.
While the cove looks inviting, it gets very crowded and several boats invariably end-up on the shoals. A much better location is on the north side of the River at (nominally) N27 31.664 W82 37.721, or anywhere along the north side. This also offers much better protection from easterlys and the northwesterlys that seem to prevail in the area. Further into the River, there's a designated "special anchorage" at about N27 31.392 W82 36.949, to the south of the Bradenton YC breakwater; and, further, an anchorage at about N27 30.966 W82 35.976 on the east side of Hooker Point (where there are no Hookers to my knowledge).
There is shoreside access at Desoto Point, where there is a Park and historical site; on the north side of the River, where there is another park at Emerson Point; and, along the shore of the River on the east side of Hooker Point. There is no convenient shoreside access from the special anchorage unless one is a
member of a yacht club with reciprocity with Bradenton YC and there there is only one small floating
dock, adjacent to the Pram shed on the west side of the Snead Island Cut, and they get very touchy if that dock gets blocked during sailing activities.
Further up-river there is a good anchorage near the Green Street Bridge with shoreside access at both
Regatta Point (and a great breakfast place--the Riverside Cafe) on the north side; and, at Twin
Dolphins (with a good waterfront bar/restaurant) on the south.
FWIW...
