The Shepherd/Donzis had both logos on the hull. So, technically not re-badged...
It is my understanding that several boats came up from FLA but, not at the same time. First a 16 SS for the 1965 TIBS, later (summer '65) another 16 and finally an 18. The 16 moulds came up in the spring of 1965 and they were used (possibly the original moulds).
The Canadian made Shepherd/Donzi 16's were always built according to the earliest layup schedule and to my knowledge not changed with the exception of some PVC stiffeners in the hatch that were perpendicular to the direction of the US made boats. Even when the US modified its procedures, Canadian production stayed the same. This consistent early build procedure may have been spelled out in the original license contract and not amended.
I have little information on hull colours however, I do know that Shepherd made yellow boats in 1965. (one sold in 2013 down London, Ontario way) I'm hoping the box-o-records will shed light on all of this.
