I can see your point re the Beneteau...and I like the sound of the Folk Boat too...
But, as I'm sure you are aware, the IOD is a bit apples v pears...good luck with finding a mooring for that, never mind an affordable one (because you won't be trailer sailing), and then there is the need for expensive parts/maintenace/sails to sail to its rating....there have been several attempts to do so hereabouts.
If you are in need of a REAL money pit, sorry I mean wealthy mans toy, there is a beautiful classic International 6m, in quite good condition (Doyle stratis sails, rod rigging etc etc) available locally for about the same price!
Trailer is 1.2 T empty...needs quite a tow vehicle!
BTW you will need a skilled crew of at least 3 even to take it to sea, 5 to race. No passengers!
Expect to spend about the same as purchase cost, annually, if you want to class race.
Great racing tho....
