I think if you buy into the theory that no retail boats were produced until after the Nov 15 Jax show, that 5-6 boats could be in the ballpark for the last 5 weeks of the year.
However, I still put stock into the theory that with completed moulds, they were popping hulls before the show. It makes no sense not to... and have the moulds idle.
If you wrap your head around this theory then, the big unknown is how long those moulds were available. If it is anywhere around 8 weeks +/- a week or so, then 10 or so boats is not out of the question even accounting for less than optimum staff working in the factory at a vastly reduced production rate of around one (1ish) Ski Sporter per week.
(I think we earlier established the peak averaged near 16 boats completed per month... = 4 per week)
