STM: 829.2
Nav. Marker / Location: Ormand Beach Bridge
Vessel Reporting: Onward
Date: 14 Nov 2010
Report: Bridge height boards read: 64.0'. About 0.75' to 1.0' of Onward’s VHF antenna (~65.25’) touched the bridge beams (this would seem to confirm the height boards are reflecting the true bridge height. Note tide data reports minimal tidal swing in this area and the reported height at transit was 0.7'
Ormand Bridge N Height Board 14Nov10
Ormand Bridge S Height Board 14Nov10
STM: 829.2
Nav. Marker / Location: Seabreeze Bridge
Vessel Reporting: Onward
Date: 14 Nov 2010
Report: The erroneous height board problem reported in 2009 has not been fixed! Height boards read 63.0’. Following the centerline of the concrete arches, the tip of Onward’s VHF antenna (~65.25’) did not touch on either the N or S span. Noted tide data for transit time: Ormand Bridge T = 0.7'; Dayton (ocean) T = +2.6; Ponce de Leon Inlet T = +2.0'
Seabreeze N Bridge N Height Board 14Nov10
Seabreeze N Bridge S Height Board 14Nov10
Seabreeze S Bridge; S Height Board 14Nov10
Seabreeze S Bridge N Height Board 14Nov10 
Onward clearing the Seabreeze N Bridge 14Nov 10; tip of VHF at 65.25' is not touching at center of bridge arch.
STM: 829.2
Nav. Marker / Location: Seabreeze Bridge
Vessel Reporting: Onward
Date: 20 Nov 2009
Report: Height boards read 63.0’. Following the centerline of the concrete arch, the tip of Onward’s VHF antenna (~65.25’) did not touch the N bridge and just flicked the arch of the S bridge. The nearby bridge tender related that bridge height boards have apparently been changed to reflect the clearance over the fenders vs the center of the span.
STM: 830.2
Nav. Marker / Location: C Carlton Black Bridge
Vessel Reporting: Onward
Date: 14 Nov 2010
Report: Same experiences as last year: Height boards read 62.25’. Water level was at the bottom of the 5th fender board. Following the centerline of the concrete arch, the tip of Onward’s VHF antenna (~65.25’) did not touch either span. Noted tide data for transit time: Ormand Bridge T = 0.7'; Dayton (ocean) T = +2.6; Ponce de Leon Inlet T = +2.0'
Carlton Black Bridge N Height Board 14Nov10
Carlton Black S Height Board 14Nov10
STM: 830.2
Nav. Marker / Location: C Carlton Black Bridge
Vessel Reporting: Onward
Date: 20 Nov 2009
Report: Height boards read 62.25’. Water level was at the bottom of the 5th fender board. Following the centerline of the concrete arch, the tip of Onward’s VHF antenna (~65.25’) did not touch either span (Min. Height = >65.25'). The nearby bridge tender related that bridge height boards have apparently been changed to reflect the clearance over the fenders vs the center of the span.
STM: 835.5
Nav. Marker / Location: Port Orange Bridge
Vessel Reporting: Onward
Date: 20 Nov 2009
Report: Height boards read 63.25’. Water level was at the middle of the 5th fender board. The tip of Onward’s VHF antenna (~65.25’) interfered by ~6” with the bridge beams (Min. Height = ~64.75').
STM: 838.0 - 847.0
Nav. Marker / Location: Ponce de Leon Inlet
Vessel Reporting: Onward
Date: 20 Nov 09
Report: There are four buoys, 1-4 marking channel approach from the N. Saw a minimum of 14'. Dredging underway last year is complete.
STM: 842.3
Nav. Marker / Location: Rockhouse Ck Anchorage
Vessel Reporting: Onward
Date: 20 Nov 09
Report: Anchored at W mouth of cut in 10-15'. Due to current and wind interaction boats needed greater separation to account for uncoordinated movement of boats at anchor.
STM: 846.5
Nav. Marker / Location: Harris Saxon Bridge
Vessel Reporting: Onward
Date: 21 Nov 2009
Report: Time: ; Tide: 1.6' @ Ponce de Leon inlet. Height boards read 66.0’. Water level was at 4th fender board. The tip of Onward’s VHF antenna (~65.25’) cleared without touching (Min. Height = <65.25').
STM: 878.8
Nav. Marker / Location: Titusville Bridge
Vessel Reporting: Onward
Date: 21 Nov 2009
Report: Construction of a new fixed bridge is underway to be completed in 2011. Construction barges and work are affecting opening and channels available for passage. Monitor and contact bridge tender on VHF Ch-9.
STM: 894.0
Nav. Marker / Location: City Point Bridge
Vessel Reporting: Onward
Date: 21 Nov 2009
Report: Time: 1430; Tide: Non-tidal area. Height boards read slightly 64.25’. Water level was at the middle of the 4th fender board. VHF antenna (~65.25@tip) had ~10” of interference with the beams of the N bridge (Min. Height = ~64.5'); but did not touch any but S beam of S bridge.
STM: 894.0
Nav. Marker / Location: City Point Bridge
Vessel Reporting: SV Swell Horizon
Date: 22 Jan 2010
Report: Time: 2119. Construction has lowered the height of the City Point Bridge, sometimes called the 528 bridge to 58 feet. This bridge is near the Barge Canal, just north of Cocoa Beach (SM 894). We have been told that this is likely to be the case for six weeks.
Near disaster tonight. Approached the City Point (528) bridge, southbound on the Atlantic ICW just north of Cocoa Beach Fl just after sunset. It was getting dark and we were straining to see the height board. Realized that construction work had covered the normal height board, and just as we were passing the fenders at the approach to the bridge we were barely able to see a sign saying that the bridge clearance was now 58 feet. As we slammed into reverse we were able to see scaffolding stretched UNDER the bridge, with no lighting and no warning. We came very close to a very nasty accident.

STM: 897.6
Nav. Marker / Location: Cocoa Bridge
Vessel Reporting: Onward
Date: 21 Nov 2009
Report: Time: 0700; Tide: Non-tidal area. Height boards read 63.1’. Water level was at top to middle of 4th fender board. Time: 1500 Tide: Non-tidal area. Onward did not make passage but anchored to check local knowledge. On 22 Nov, High Priority, a sister ship reported that they had safely passed under the bridge about 12 Nov at a height board reading of 62’. On 24 Nov, Height board reading was 63.1’ . Water level was at the middle to bottom of the 4th fender board. Onward safely transited the bridge; the VHF antenna interfered with the bridge beams by ~ 10” (Min. Height = ~64.5').
