I have paddled 3 of the 4 Kaku boats, all except the wahoo 10.5. They are all great boats and very stable and well made.
I rented them several times before buying both the voodoo and that wahoo 12.5 so that if my wife or one of the boys come with me, we each have something ride.
With all of the gear tracks, you can really outfit them any way you want, so their versatility is awesome.
On top of all that, the customer service from Levin and his dealers is unmatched.
