also I notice a lot of manufacturers don't seem to even have a board specifically for down winding in their ranges ?
Most manufacturers that you are referring to have prioritised racing over downwinding. Some of them actually seem to think it's the same thing.
A touring board is designed for mostly flat water and comfort. You will find most touring boards at least 30" wide. They tend to struggle to catch ocean swells as they don't have the speed .
There are many different types of race board so it is hard to pin down exactly what defines a race board. Some are 12'6", some are 14', some are 17' and beyond (aka - Unlimited). These Unlimited boards most often come with a steering system. Some race boards are designed for flat water, some for surf races, some are all rounders - they do everything fairly well but nothing perfectly. Some downwind well, others don't.
If your intention is just to downwind and catch the ocean swells, then there is no substitute for a board designed specifically for downwinding.
As for the width of boards, what you will find is that a 14' x 28" board is generally about as stable as your 9'5" x 32". Or at least, not that much less stable. The length of a 14' board aids stability significantly. Unlimited length boards are even more stable again and that makes up for the narrow width.
Again, if your intention is to downwind, then you should be looking at at least a 14' but if your storage and transport allows, then an Unlimited downwind board with steering is the duck's nuts.
