30 to 70 miles off the Treasure Coast and Vero Beach
A run of that length drives fuel and range planning for a center console, so settle it before choosing a waypoint. Check the official marine forecast for wind, wave height and period before leaving the dock. The 1600 ft drop grounds at 35 to 45 miles sit inside this band. For how this port compares with the rest of the coast, see the wider Atlantic Southeast picture (see also the wider Atlantic Southeast guide).
