Hi Mike.
The reference was for you. I especially did this test to see for myself the effect of reversing a single prop boat. After a while when under power, it does veer off course, so I also tried gentle reversing and moved the tiller to gain more information. Once she goes off course, it's difficult to straighten her up again.
The secret seems to be a rapid acceleration to rear and stop the props when underway. She then cruises in a straight line and can actually be steered a bit.
Hope this helps you with your problem
Cheers

I'm thinking of selling her to fund the next one. If anyone is interested then I will do a full ad in the correct section.
