Ono Island Bridge Clearance

The Ono Island bridge is a fixed span with an average clearance of about 24 feet at high tide. That clearance improves slightly at low tide, adding another foot or two, which means a vessel around 25–26 feet in height might pass under during a favorable tide. This is critical information when considering a boat with a flybridge, radar arch, or tall tower.

Most center consoles, cruisers, and pontoons fall well within this limit. Personally, I’ve found that even larger 30- to 38-foot boats, like a Grady-White Canyon or a Cruisers 38 GLS, comfortably pass under the bridge with room to spare. Homeowners with exceptionally tall vessels often choose lots on the north side of the island—along Bayou St. John—to avoid the bridge altogether and gain direct access to the Gulf.

Water Depth Around the Island

Bayou St. John typically offers 10 to 12 feet of water depth near many of the docks, making it ideal for deeper-draft boats and larger vessels. Old River, on the south side of the island, is slightly shallower with depths around 7 to 8 feet mid-channel, and some fringe areas may dip as low as 5 feet at low tide.

Within Ono’s private canals and harbors, depths vary, but many are naturally deep or have been dredged to accommodate boats with 3 to 5 feet of draft. If you're considering a home on a canal, I always recommend checking the depth at your dock at low tide—especially if you're planning to bring in a larger boat.

Beam and Width Considerations

Beam is almost never a concern when boating around Ono. The bridge spans a natural channel with plenty of horizontal clearance. Boats with beams of 10 to 13 feet are common and easily navigate the waters here. The only caveat is when docking at your own slip—make sure it’s wide enough to allow maneuvering room.
