Sometimes we forget the existing relation between a sail and the mast it was designed for. Choosing between SDM or RDM is only the starting point for a very wide set of options. We will try to explain all of them.
The main aspect is the curve. Some time ago Unifiber started to publish a list of suitable masts for each sail, up to now I didn’t find anything better or more useful than this.
But this isn’t the end, there are other aspects like the carbon %, the IMCS, etc.
If you are patient we will be covering all the subjects!!
