Tow

After 20 years of sailing, I experienced my first tow today. We had a beautiful sail in 10 knots of breeze, and then we started the motor to head home. We noticed the engine temperature running very high after a few minutes, so we slowed down to see if the engine temperature would drop. No luck, so we shut the engine down and called Tow Boat US. They arrived in about 20 minutes, and hauled us in, through the draw bridge and to our dock. We restarted the engine briefly to put the boat in the slip, and shut everything down, with the engine starting to overheat again. We think that this might be a bad thermostat, or maybe a fresh water coolant leak. I will spend some time in the engine room this week figuring out the problem.
