We are trying to figure out if we can get under the Brooks Bridge in Fort Walton Beach FL. It is listed on the charts as 50' but the tidal markers show 47 - 48 ish. Locals tell us this is not a 50' bridge, but everybody has different opinions, no facts. We climbed the mast and measured and are at 49'6" to the top of the expensive stuff. If any IP 350's have information that could help us, please give us a shout. Thanks!
