One-of-a-kind electric sailboat. If this were a car, it would be considered a vintage restomod. It is a 1975 ODay 27. If you are not familiar with this boat, learn about it here:

youtu.be/SPi_PS7j-Y8This sloop has been through a 5-year reconditioning and modernization. It started out with an Atomic 4 gas engine. The engine and fuel tank were replaced with a SolidNav electric motor and 4, 170 amp-hour batteries in series to create a 48-volt system. The result is a very reliable and quiet boat to operate. It charges plugged into the dock overnight. Its range depends on how fast the boat is going, but on average, one can expect 20-25 miles on a charge.
That may not seem like much, but this is a sailboat, so the inboard motor isnt needed much. And when the boat is under sail, the spinning prop regenerates the batteries.
There is a new prop and prop shaft.
It also has a new Mercury 9.9 electric-start outboard motor with 12 gallons of gas onboard. The outboard is a useful addition. Having directional thrust makes slow, close-quarter maneuvering easier than with any inboard. And the outboard has an alternator which charges the house batteries. When there isnt enough wind, the gas outboard extends the powered range to about 75 miles.
In addition to the propulsion batteries, it has two 232 amp-hour six-volt deep cycle house batteries in series, which powers all 12-volt systems onboard. These batteries are charged by shore power with a new marine-grade charger and with the outboard alternator.
There is a 48-volt 4,000-watt inverter that supplies 110-volt power when the boat is not connected to shore power. Shore power connects to two onboard 110-volt circuits, one 15-amp and one 30-amp.
There is new wiring for the 48-volt, 12-volt, and 110-volt systems.
