In 2020 at our Ford Yacht Club there was an early morning fire onboard a boat that quickly spread and destroyed/damaged several boats next to it.
...To date, fire inspectors surmised it was due to below grade approved dockside electrical connections.
Lessons learned are that there are ABSOLUTELY NO SHORTCUTS in saving money by less than approved and properly installed dockside electrical connections! Especially when it effects your dockside boating neighbors!!!
