I've been onboard Kekoa a few months back, met the builders/owners (same people) you can find out more about their boat/project at
http://www.losttrades.com . Very cool people, worked very hard on this boat and seemed to be well constructed etc, it was their second such boat -- built the other one 5 years or so ago, chartered her extensively and then sold it for 500k. This looks like it falls on the delivery crew, why were they out in those conditions in the first place? That cat can cover a LOT of ground quickly and shouldn't have left in questionable weather, that being said Kekoa was built more for being a day trip kind of boat, certified to take 75+ passengers on day sails in the caribbean not exactly designed for blue water
I hope she's found and afloat.
