Sunset Bay in Stuart on the Okachobee waterway, just west of the Roosevelt Bridge is pretty nice, and have live a boards. I think they are a little fussy about
sanding and things that would possible mess up neighboring
boats, but you are close to Publix and to a couple of West Marines. St Lucie inlet isn't as bad as some make it out to be. A quick call to Sea Tow will give you
current conditions and if the buoys are accurate. Port St Lucie is about halfway between Ft Pierce and St Lucie inlets.
