A brutal cold snap has turned parts of the Cincinnati riverfront into an accidental boat graveyard, with at least seven recreational vessels ending up partially or fully submerged at area marinas, according to owners and dock crews. Mid-size powerboats and a large 56-foot vessel were discovered listing in their slips or sitting with their sterns in the mud after ice and freezing temperatures overwhelmed winter protection systems. Now, boat owners are staring down big repair bills and hustling to check pumps and electronics before the coming thaws reveal even more damage.
WKRC documented seven boats that either went under or had to be pulled to safety. One Carver 30 at Harbor Towne Marina was about 85% submerged, with its reportedly pricey electronics now soaked and likely ruined. At Four Seasons Marina, a 56-foot vessel ended up with its stern resting on the harbor bottom while the dock held its bow. Dock workers told the station that frozen bilge pumps and iced-over fittings were the main culprits. “So, with the historic cold we got this year, I mean, I haven’t seen it in 20 years,” JT Marine owner Tyler Shepherd told WKRC, which also reported that crews had to core-drill through as much as eight inches of ice just to reach damaged equipment.
Why ice does so much damage
When water freezes, it expands and can put enormous stress on engines, hoses and through-hull fittings, which can lead to damage that often stays hidden until spring, according to BoatUS. Marine guides and technicians also caution that float switches, bilge-pump wiring and batteries can fail in extreme cold or when discharge lines freeze, which leaves a boat quietly taking on water at the dock, Practical Sailor reports. That combination of cracked plumbing, failed pumps and plugged scuppers is what technicians say is behind this week’s sinkings.
River and marina conditions
Sections of the Ohio River developed thick, stubborn ice that slowed vessel traffic and required close monitoring by the U.S. Army Corps of Engineers, according to local coverage. Spectrum News reported that Corps crews were flushing ice through locks and watching for potential jams, while WDRB described how ice buildup has slowed lock operations. Marina staff told local reporters that in some cases ice may have temporarily plugged leaks. As those icy plugs melt during a thaw, they warned, additional boats could still be at risk of going under.
