What to know before you launch
- Rinse your trailer and engine with fresh water after launching in salt — corrosion is the enemy on Florida's coast.
- Even with multiple lanes, prep in the staging area first so you're not tying up a lane while loading gear.
- Always check current tides, wind, and marine forecasts before you launch — Florida afternoons can turn stormy fast.
