knotflying,
Your clarification of whether to keep the canvas or the kids, reminded me of an experience I had years ago on a Hunter 27 I owned...
It had a very open transom and when I had few in-laws aboard for a relaxing but crowded cockpit sail on an breezy day. My sister-in-law (always a very tighly twisted, never a thought un-said sort of gal) decided she should point out that "boats are for fools that have no sense of a dollars value, it's almost negligent to allow children on boats, does this thing always tip so dangerously (5 deg heel?), etc...etc..." She especially was concerned about falling over the side or especially being washed over the open transom and out to sea. I explained, "should that happen (while suppressing the urge to prove her right) her life jacket would save her from sinking and that the low transom and its folding ladder would allow for easy re-boarding (probably against the wishes of the rest of my "crew")". That didn't help much because I'm sure she saw the look in my eye and was certain that I'd just sail away without her. I decided to show her my daughter's harness and life line we used when she was small...that gave my sister-in-law the idea that a "tether" for her would be a good idea. I tied a length of 1/2" braid into a loop with a slipknot and handed it to her, mentioning that she should be careful not to allow it to become tangled. Then I turned and tied the other end to a handy cleat. When I turned back ...she had the loop around her neck!!...
As I began to tell her to put it around her waist my father-in-law tapped me on the arm, shook his head, grinned, and loudly said,...(I'll never forget his exact words)...
"Well, thats all well taken care of,...now, lets all see how fast this thing can go!!".
True story.
