The Dingo 6.5 is a production series Mini, and has been known to be somewhat competitive in the right hands, though that class is dominated by the Pogo 2, among series boats.
I take it that Yaka is just a more civilized, cruiser-friendly Dingo 6.5, with the twin keels giving it the ability to dry out with the tide.
It would be natural to want to make larger versions of each, I suppose, though it sure seems that space is getting a bit crowded.
As I was taking my midday walk, a short time ago, I came to the conclusion that I will need to schedule a trip to Europe next year to visit the various yards and get a first hand look at the boats that are tempting me, including the Malango 888 and 999, the SeaScape 27, the Archambault 31 (and the new 35 by then), the Dehler 32 and 38, and who knows what else, since in 12 months I expect to see even more new, enticing interesting boats.
Fortunately, this summer I'll get a first-hand look at the soon-to-be-launched J/88!
Now excuse me while I try to scrounge a ride for the 2013 Melges 24 Worlds, in San Francisco.
