Any where north of I-10 is too far north!! If I get wet I can dry off! Hurricane comes, cruise across the bay and get put on the yard (except another Katrina!) In that case you file your insurance...I guess not having sun and warm water has some advantages. ;-)
"hard to adjust dock lines under adverse conditions, wish we had floating!""
Some spots on the coast will have 10-15 ft of storm surge over high normal moon tide.
Few floating docks have the ability to stay on long enough pilings, so the entire marina floats off.
