Okay, This topic came up ...again (but, elsewhere).
So, I just re-read all of the posts from the beginning. I think it helps to have left this alone for a while.... But, here's a thought...
Given that the Formula Jr. was already in existence... And further, that it was reluctantly sold. We know the Jr. gave rise to the Ski Sporter on paper. So, it follows that a short cut in the development of a similar boat for DONZI could have been a reworking of the Formula Jr. plug and / or a mould.
This plug could have still been in existence and if so, access would not have been an issue. To modify details of the Jr. to become the Ski Sporter would have taken much less time than starting from scratch to produce a similar boat. Especially if Walt/Don knew what they wanted to change.
The result would undoubtedly have been closer to a finished product without as much need for performance "adjustments" that also take time ...
If this is what happened it would have also been a cost saving procedure and might have let Don regain some inner satisfaction after selling the Jr.
Plausible?
