I had Hoop Dancer (2006) in charter for its first 5 years and replaced the the belts when I took it out of that service in 2011. Last year 2016 the belts looked a little worn so I replaced them and was going to buy an extra set for spares but didn’t on the basis of that advice. They still look new. This year we were out about 60 days total, including one 30 day trip. We had pretty good wind this year so less than 100 hrs on the motor. Last year about 45 days total but over 100hrs as we had to motor much in Puget Sound. In other years I have averaged about 50hrs. Engine is a Yanmar 3YM30.
