1572Re: Rescue Minor "Bingey" launched
- Jul 9, 2007Curtis,
Congratulations on the launch, and I like the choice of name. Photo #3
shows a lot of water that you are dragging around in that cavity. How
can you ever get it trimmed with such a large, changeable, weight in
the stern? Is there any way to seal around the temporary lower unit?
Any hogging is not evident in the low resolution photos. How severe is it?
Great job in a timely manner!
