Here ya go:
Built 2010 with aft mast and wishbone reverse vang for performance. Keshi has sailed around Australia
since then in some very challenging conditions on all points of sail. It sails beautifully as I can attest to personally, having test sailed her.
Big advantages in sail handling for shorthanded crew or singlehanded ( the owner is in his mid 70's and single hands usually), light air performance, and balance working to weather
designers VPLP saw a 52 foot FreeFlow sister ship being built in China
and closely examined the aft mast engineering. Just co-incidentally (ha ha ha) the Lagoon
52 & 39 appeared thereafter. You would not know this from reading their marketing
blabla, of course. It is all due to their "innovation".
But there are some aft mast implementations that have not considered the support engineering considerations well enough, let's put it that way.
You may also want to consider the performance aspects and look up how many performance sailing craft are using reverse vang configuration.
