Good morning
From your post I infer that you will be approaching Biscayne Bay from the Atlantic via Biscayne Channel. I am also assuming that you have a
dinghy.
With an 80’ mast you are limited by the Rickenbacker Causeway to the north and by the Card Sound Bridge to the south.
With a
shallow draft cat (less than 4 ft) you have a lot of options.
The most obvious and closest to approach is No Name Harbor. You can
anchor in the harbor (first come, first serve…..very crowded on weekend days…..good place to shelter from thunderstorms) or in the channel immediately outside. (Fairly steady and early
fishing boat traffic). It is easy to
dinghy in and you are in a state park.
Very dog friendly (leashed). Big park. About a mile to Ace
Hardware, Winn Dixie and a bunch of restaurants. If you get an Uber back you have to enter a state park entrance but they usually waive the entry fee if you explain what you’re doing)
You can also
anchor at (just off of) Dinner Key Marina on the mainland
Miami side and ther is a large dinghy
dock there as well. Take a lock to that one but there is a lot of dog friendly park there.
Much less urban is Boca Chita. It’s a 6’ channel at low tide, and a crowded little harbor, but it is easy to dinghy in. It’s a National Park and I’m pretty sure that
dogs are not allowed, but it’s
Miami and enforcement might not be 100%. I have seen
dogs there, loud
music, parties…..all kinds of things that are against the rules…..and a lot seems to depend on the presence of rangers.
Further south is Black Point Marina. Dinghy
dock, big park, dogs ok, and a cafe but not walking distance to anything else.
Way further south you could anchor near the Card Sound Bridge (pay attention to special
regulations regarding being in the park) and dingy around to
Alabama Jacks. I haven’t done this in a while, but it’s a motorcycle bar and I’m pretty sure you can take tigers in there…..so dogs probably ok.
