I have been a happy member to C- Tow for 5 Years and needed their help twice.
One time my raw water pump failed while on a cruise, they told me if I could find the part locally in Sydney they would pick it up and deliver it to me on Saltspring Island, source the part and 2 hours later the captain handed me the part on the dock, no charge as I am a member.
Second time my fuel pump packed it in and had to be towed, I waited for 2 hours and they came and towed me back to home marina 2 hours away again no cost to me. I am a big supporter of their service and recommend it.
